Japan: A new island appears in the Ogasawara Islands - November 2013
Active volcanoes (Sep 28, 2012)
"Of course all volcanoes will explode, as this is going to be a very severe pole shift. What about the months and years preceding the pole shift? It is no secret that Mammoth Lake and the caldera of Yellowstone are warming up, and the populace has been prepared for these occurrences by the movie Volcano where there, in the middle of LA, lava is bubbling up. In fact, there is a fault line running from the approximate San Diego/LA area, up into the Sierras, and this is liable to rupture rather violently during one of the quakes that precedes the pole shift by some months. Volcanic eruptions from that area in the Sierras can be expected. Will Mount St. Helen erupt? All volcanoes that have been active within the memory of man will begin spewing and burping and oozing, and many that were not expected to become active will reactive. " ZetaTalk - Feb 15, 2000

The eruption on La Palma in 1971 drove forty million cubic meters of magmatic material to the outside and lasted 24 days. The El Hierro could take up to a month and a half and fifty million cubic meters
GUERRA PEDRO Scientists working for weeks in El Hierro believe the volcano that rumbles beneath the soil of the smallest island of the Canary Islands can hide in the magma chamber more material than Teneguía expelled in La Palma, in 1971 . This conclusion was reached after complex mathematical calculations that lead them to have a real close approximation of what lies along the 12 km route they believe has made the magma over the past three months, after the last July, the first detected earthquakes of the crisis on alert scientists from around the world. Because there is more material magmatic eruption could also be longer than 40 years ago just occurred in the neighboring island.
On October 26, 1971 the Teneguía made an appearance in La Palma. The eruption lasted over 24 days, until 18 November and, according to studies, it is believed that drove about forty million cubic meters of magma. At that time, due to lack of technical means, nothing could be anticipated, but after the end of the eruption itself could be studied in detail the volcano and reach different conclusions. One was the amount of magma expelled.
Now, just 40 years later, scientists are based on the deformation suffered by the island in the last three months (about 5 centimeters) and in the path of the lava under the earth during that time (about 12 miles) to think that under El Hierro, are expecting their output near 50 million cubic meters of lava.
With these data on the table, the rash that breaks through at this time under the waters of the Sea Calm in La Restinga, could take between a month and a half months, according to estimates calculated by the scientific community moved to Meridian Island.
The notice
After scientific analysis is performed to detail the volcano El Hierro and compared with other parameters of eruptions produced elsewhere in the world, researchers are able now to predict certain things about the beast that awaits his exit under the Island for example, before the occurrence of the dangerous phase of the eruption (the explosions that eject magmatic material under pressure) it could take between seven and eight hours after what is considered an alert phase, when large columns begin to appear smoke with steam generated by the accumulation of gas in the seabed.
After Saturday scientists detect the presence of magmatic material steaming volcanic spot on since last Wednesday, affecting the Mar de Las Calmas, the next thing will be, as that will be building what scientists call the building volcano, which is nothing more than the accumulation of lava on the seafloor to be getting closer and closer to the surface, are columns of smoke generated by the steam from the gas eruption. These columns of smoke could reach, as the director of the National Geographic Institute (IGN), María José Blanco, "five hundred feet high," and besides being very dramatic, pose no risk to the public.
About seven-eight hours later, investigators believe, come the dangerous phase: a sequence of bursts generated by the contact of magmatic material to 1,200 degrees centigrade, with water as the depth decreases the growth of building volcano. White explained yesterday, these explosions can move magmatic material, mainly ash, up to four or five miles away, which fully reach the village of La Restinga and so far, is not believed to reach the town of El Pinar, located upslope of La Restinga.
Once that phase occurs, scientists believe very explosive, subaerial construction would begin, which could result, as explained in the day yesterday, the birth of an island in the area of the rash. Even scientists believe, this island could be attached to the island of El Hierro on the si

Chile, Puyehue volcano - Argentina, Uruguay halt flights due to volcanic ash
Argentina and Uruguay both suspended flights at major airports Sunday due to dangerous ash from neighboring Chile's Puyehue volcano, which has disrupted global travel since it erupted earlier this year. Authorities suspended or canceled numerous international flights serving the United States, Peru and Brazil at the Ezeiza airport south of the capital, hours after shutting off Jorge Newbery airport in Buenos Aires. "We need the ash cloud to pass" before the airlines operating out of the airport, which serves domestic and regional flights, resume their operations, Transport Secretary Juan Pablo Schiavi told local television. Argentina's LAN airline said in a statement that international as well as domestic flights were affected, including routs to Mendoza on the steps of the Andes mountains toward the Chilean border, and Ushuaia in the far south. In Uruguay, 15 international flights were canceled at Montevideo's international Carrasco airport, largely affecting flights to Chile and neighboring Argentina and Brazil. Brazilian air carriers Gol and Tam both canceled their flights Sunday to Buenos Aires and Montevideo, company officials said.
Air traffic in the southern hemisphere has been hit hard in recent months. Airports in Buenos Aires and Montevideo and later those in Australia and New Zealand were paralyzed when the volcano high in the Andes roared back to life in June after sleeping dormant for half a century. Since June most airports in Argentina have been forced into shutdowns at some point due to dangerous ash threatening the safety of commercial airliners. The ash cloud also dampened hopes of a good tourist season at the Argentine ski resort of Bariloche, some 1,600 kilometers (1,000 miles) southwest of Buenos Aires and just 100 kilometers (60 miles) southeast of Puyehue, as flights were canceled and pristine snow was darkened by the spewing volcano. Ash poses a significant threat to aircraft because once sucked into engines, it can be transformed into molten glass by the high temperatures and potentially cause an engine to fail. The eruption of the Icelandic volcano Eyjafjoll last year caused the greatest shutdown of air space in peacetime Europe, with more than 100,000 flights canceled and eight million passengers affected.

Volcanic tremor signal continues to moderate. The latest earthquakes are mostly registered northwest of Frontera.
ACNPRESS The population of El Hierro has become to feel a tremor in this case of 2.6 magnitude on the Richter scale, which was preceded on Friday by four earthquakes, all of intensity less than 1.8 degrees .
The main quake occurred at 10:36 hours and about 24 miles deep, north-west Frontera, specifically in the area of small seismic swarm was detected in recent days in the center of Valle del Golfo, at its marine part.
The other occurred at similar depths in excess of 20 kilometers and in the same area except one, whose epicenter was located southwest of El Pinar, at a depth of 17 kilometers.
On the other hand, the Association Volcano Canarias Islands (Avcan) mentions on its Facebook page, ´Actualidad Volcánica de Canarias´the " impressive lineup "of eight of the nine earthquakes in the northwest and southeast axis (NNW-SSE), where práctically is located all volcanic seismic activity these days.
Besides, still detected a "significant" sign of tremor, which continues with little variation and events "long period", which experts generally attributed to an active role of fluids within the volcanic conduits, caused by resonance effects or flow instability.
Also, note that the latest data from the National Geographic Institute (IGN) show that seismic activity continues to "moderate, with some moderate earthquakes located in low magnitude," too deep.

Turkey fears volcano eruption
Turkish seismologists fear that the earthquakes that hit the province of Van on October 23 can cause eruption of Nemrut volcano located northwards of Lake Van.
Mt. Nemrut is near Tatvan, a small town in the eastern Anatolian province of Bitlis. The mountain rises from the southwestern shore of Lake Van, and enters the district of Ahlat to the north.
At least 217 were killed and more than 1,000 people injured when a powerful earthquake struck Turkey, collapsing dozens of buildings and pulling down phone and power lines in the southeast of the country, officials and witnesses said. More than 1,000 people are feared killed in the earthquake.
Another magnitude 6.1 earthquake, which was the second to rock the country in the past 24 hours, was registered about 20 km (12 miles) from the city of Van at the depth of some 10 km (6.2 miles).

Indonesia, Mt. Lokon - Mt.Lokon erupted again, now spewing incandescent materials up to a height of 1,200 meters (3,930 feet)
INDONESIA's Mount Lokon erupted again on Wednesday afternoon after showing increased volcanic activity since the day before, officials said on Thursday. Mount Lokon, which is located on the northern tip of the island of Sulawesi, is now spewing incandescent materials up to a height of 1,200 meters (3,930 feet), Farid Ruskanda Bina, head of the Mount Lokon observation post in Tomohon, told the Antara news agency. Farid said the eruption came shortly after increased seismic activity was recorded, while Volcanology and Geology Disaster Mitigation Center chief Surono noted that Mount Lokon is one of the two Indonesian volcanoes currently on Alert Level 3, which is also known as "Siaga" in the country. The other volcano on Siaga status is Mount Ibu in North Maluku. Both volcanoes are currently considered the most worrisome in the country since they have been consistently erupting ash clouds which reach up to 2.5 kilometers (1.5 mile) high. However, Surono said the eruptions have not placed local residents in danger. Nonetheless, Surono noted that unlike developed countries such as Japan, where each monitoring expert is assigned one volcano, in Indonesia, each expert has to monitor five volcanoes, making it more difficult to anticipate such natural disasters.
The center has adopted four levels of alert status: "Normal" (Level 1), "Waspada" (Level 2), "Siaga" (Level 3) and "Awas" (Level 4). On August 17, Mount Lokon began to spew volcanic ash which fell as far away as the Kinilow I village and the Tinoor areas in North Tomohon sub district, which is a short distance from Lokon's crater. And on August 28, Mount Lokon erupted as many as 12 times, followed by constant volcanic activity in the following weeks. Dozens of active volcanoes in Indonesia are part of the Pacific Ring of Fire, known for frequent earthquakes and volcanic eruptions. Next to Mount Lokon is its volcanic twin, Mount Empung, just 2.2 kilometers (1.3 miles) away. One of Indonesia's most active volcanoes is Mount Merapi, which is located on the island of Java near Jogjakarta, the country's second-most visited area after Bali. Last year, more than 300 people were killed in a series of eruptions between October and November which also displaced over 300,000 people.

Chile, Hudson volcano stirs up, Chile evacuates residents
Chile’s government said on Wednesday that it’s evacuating around 100 residents within 25 miles of the Hudson volcano after the volcano began to stir up. On Wednesday, the Hudson volcano began to show signs of a possible imminent eruption after it rocketed a jet of steam roughly half a mile into the air. Seismic activity related to the volcano also began to pick up on Wednesday, one of which caused an avalanche in the area. “We can’t rule out that this volcanic activity could increase in the coming hours and produce an eruption,” said Interior Minister Rodrigo Hinzpeter. If the Hudson volcano erupts, and officials believe it is possible that it will, it will be one of a string of volcanoes to erupt over the past several years in Chile, the government said. A volcano erupted in June of this year, which followed an eruption of the long-dormant Chaiten volcano in 2008. The Hudson volcano is part of one of about 2,000 volcanoes in Chile. The last time the Hudson volcano erupted was in August of 1991. It caused millions in damages, mostly to local farms.

The increased frequency and intensity of earthquakes could be an indication of a new eruption in the north
EFE authorities and scientists remain alert 24 hours before any scenario that may occur on the island of El Hierro, after the increased frequency and intensity of earthquakes in recent days to suggest the possibility of an eruption, this time in the north of the island and probably underwater.
The Director General of Security and Emergency of the Canary Islands, Juan Santana, told Efe that the two most likely scenarios are addressed by the decrease of intensity of seismic events or a fracture and a rise of magma giving rise to a new eruption .
The eruption of the October 10 still no news off the coast south of El Hierro, in the vicinity of La Restinga, which has reduced the pressure in the system since then, Santana said, but now the seismicity is increasing in the north, in front to Frontera. coast.
The largest of these earthquakes, recorded this Sunday morning, has reached the magnitude 3.9 on the Richter scale, but has not altered the seismic alert level on the island, which is generally yellow light and red for the area La Restinga.
Scientists are inclined to recent earthquakes are magmatic and not tectonic origin and are now trying to follow its progress.
"Do not rule out anything," but in case of eruption is likely to be underwater, the official said Security and Emergency.
Earthquakes are occurring at a distance of between four and twelve kilometers from the coast at a depth around 20 km.
Currently there are no new measures for the population, but it is possible that the tunnels Roquille critical in the communication on the island because it connects the capital, Valverde, with Frontera closed again if you keep increasing the intensity of the movements seismic.
People should remain calm and attentive to the events, said Juan Santana

There are new pieces of magma to the surface of the sea off the coast of La Restinga. The spot generated at sea by the volcanic process is enlarged
EFE submarine volcano has returned to El Hierro today eject pyroclasts (fragments of magma) steaming the sea surface off the coast of La Restinga, as confirmed to Efe Canary Islands Government.
Residents of the coastal town closest to the eruption have noticed this afternoon that the spot generated at sea by the volcanic process is enlarged and has taken a darker side.
That change is that the volcano has returned to expel pyroclastics that reach the surface of the sea still glowing and smoking, as occurred on October 15, according to the information handled by the scientific committee of the Civil Protection Plan for Risk volcanic Islands (Pevolca).
In addition, this time it has found that magma fragments emerging from the volcano are larger then and cause a darker color in the water.
A spokeswoman for the General Directorate of Security and Emergency Canary-the body that coordinates the Pevolca-has told Efe that, according to scientists, this expulsion of magma is part of the same process that began on October 10.
The first visual evidence of this eruption were precisely sulfur smelling spots that were detected two days later and final confirmation came with the smoldering pyroclastic that emerged on day 15.

The volcano launches smoking pyroclastics and a new eruption is expected in the north
The stain of the Calm Sea darkens and scientists are studying whether changes in the seismicity may be the prelude to another eruption. The Island records two types of movements, 25 and 15 km depth
C. M. M. - Las Palmas de Gran Canaria submarine volcano El Hierro relaunched yesterday smoldering pyroclastic, although this time, larger than the 12th of October. "This is part of the natural process," said Carmen Lopez, a scientist at the National Geographic Institute (IGN), an organization that continues monitoring the seismicity of the island and is evaluating whether changes in recent days, with earthquakes that reached 3.9 degrees [last night at 22. 06 in Frontera] and moves at 15 km depth, may be the prelude of another eruption, this time in the north. The residents of La Restinga could see that the stain of the Calm Sea darkened after a day of 120 earthquakes [at press time].
The working group of the Scientific Committee meeting yesterday, which included representatives of non-tip, the National Geographic Institute (IGN), the Centro Superior de Investigaciones Científicas (CSIC) and the Spanish Institute of Oceanography (IEO), explained that for a hand, we observe a seismicity occurs at 20-26 km depth and is associated with a possible feedback mechanism process magmatic eruption in progress. "It's the part that feeds the shallower seismicity and is similar to the one we had in July. This is the one with more ability to move and you are registering greater magnitudes," said Lopez, who recalled that the eruption tremor the south is "stable"
The other scenario is 10-15 km depth, and "it could be valued as a precursor to an eruption, although it is early to forecast, since the acceleration of seismicity at that depth, shallower, not producing a deformation increase ", stated the Pevolca.
The deformation would have to provide evidence in the coming days designed to ensure that there would be a new source of emission in the north. Carmen Lopez warned that "the shallower seismicity referred to the north there to watch her, but is smaller." "For now, we see no signs of it happening eruption is imminent, because there has been significant acceleration in the previous deformation and material output acceleration was very important and obvious," he said.
According to reports from scientists at the University of Cadiz, and specifically in reference to ground deformation, also shows two different scenarios. The south of the island shows a remission in increasing deformation, clearly marked by the eruption process and that is evident in the data recorded in the GPS station of La Restinga. In the north of the island, however, there was an increase of the deformation in the northern part and to a lesser extent in the East, led by an acceleration in GPS station located in the NW of the Gulf. As for gases, Involcan is studying helium , el helio,because a month before the eruption of La Restinga there was a significant increase in the gas.
But in addition to the depth and deformation must be other factors to talk of an imminent eruption. "That the seismicity is a little harder is not the only precursor. There is a seismic energy release faster, with higher magnitudes, but you can not give meaning to each particular event, but all the events globally." As for the guts of the phenomenon, "it is important to understand that everything is connected. The process has several points where magma feedback stays until he can go out and do it for the south, but the whole process of north is connected with this activity, "he described. In this event, "there is no magma chamber, but a deeper reservoirs are fed by magmatic material to the shallower parts. The process will end when the flow ceases, the magma comes out one end and do not really know more," concluded.

The movement recorded by the IGN has been felt by the inhabitants at 7.54 hours
LAPROVINCIA.ES / Reuters The islanders have woken up on Wednesday with a new movement that has shaken the whole island. The National Geographic Institute (IGN) has been in El Hierro, an earthquake of magnitude 4 Frontera northwest at 20 kilometers deep. The tremors were felt throughout the island, as some point to Canary islanders told Radio La Autonomic, and took place at 07.56 hours.
This earthquake is one of the 40 that now has seen the National Geographic Institute and was held to twenty feet deep northwest of the town of Frontera, in the north of the Canary island of El Hierro. Most earthquakes in recent days are recorded in the north of the island, while some are produced in the area of the municipality of El Pinar, in the south, where there has been an underwater volcanic eruption.
Since the beginning of the seismic-volcanic crisis in El Hierro, on 19 July, the National Geographic Institute instrumental recorded a whopping 10 832 earthquakes, although none so far has exceeded the barrier of 4 on the Richter scale , although there has been close.
Scientists do not rule out that there is a new eruption is imminent, but the Emergency Military Unit (UME) has moved to El Hierro campaign shelter can accommodate 2,000 people at the request of Civil Protection Plan for Volcanic Risk Canary Islands (Pevolca), if necessary to face a new evacuation.
The National Geographic Institute scientists have detected an increase in CO2 levels higher than usual on the island of El Hierro. A situation that commonly occurs in the moments preceding a new eruptive phase, which together with the magnitude of recent earthquakes recorded may be an indicator of a new eruption could take place again in the sea, by all indications and data analyzed so far.

For now, the Canaries Government dismisses the need to evacuate again La Restinga, El Hierro population closer to the underwater eruption that began on October 10 in the Sea of Calm,
Civil Protection Managers met this morning with representatives of the scientific team traveled to the island to analyze the changes that have occurred in recent days in the eruption, which has again thrown to the surface steaming remains of magma (pyroclastic ) and caused vibrations felt in La Restinga.
Experts believe that vibration is associated with a discontinuous pulse dynamics in the tremor signal, which is the indicator of the volcanic eruption.

Bolivia, Uturuncu volcano - Magma said rising in ancient volcano
Magma is rising in a Bolivian volcano that last erupted 300,000 years ago, a U.S. research team monitoring the mountain says.
Researchers from Cornell University, part of an international team studying the Uturuncu volcano, say the magma is uplifting rapidly.
"Uturuncu -- a volcano in the Bolivian Andes Mountains -- was thought to be inactive," Cornell geologist Matt Pritchard said in a university release Tuesday. "The region is populated by 'supervolcanoes' that erupted between 1 (million) and 10 million years ago.
"Now the Uturuncu magma is accumulating in the crust and we're observing whether it is moving upward toward the surface," said Pritchard, who is accompanied in the research by Cornell graduate students Jennifer Jay and Scott Henderson.
"Right now, we have no reason to think that an eruption is imminent," he said.
"The area at Uturuncu has had hundreds of shallow earthquakes per year, but the rate of earthquakes increased briefly due to last year's tremors in Chile," Pritchard said. "These characteristics are unusual for a volcano that has not erupted in 300,000 years."

Chile, Hudson volcano - Two Chilean volcanoes were under alert status as Hudson volcano’s rumblings combined with those of Cordón Caulle
Hudson spewed a column of steam and ash that soared more than 3 miles into the sky about 1,000 miles south of Chile’s capital, Santiago.
Officials evacuated 119 people from the immediate area around Hudson as snow melted by the volcano’s fresh internal warmth caused the Aysen River to overflow its banks.
Hudson has erupted twice in the last 60 years. Its explosions in August 1991 dumped ash 18 inches deep downwind, killing an estimated 1.5 million sheep in adjacent areas of Argentina.

The graphics offered by IGN show the difference between the tremor that records of El Hierro and Gran Canaria
LAPROVINCIA.ES The National Geographic Institute (IGN) detected in the late hours of Friday that volcanic tremor signal on the island of El Hierro maintains significant levels of intensity. This phenomenon has been accompanied by about 25 earthquakes, the largest one with a magnitude of 3.8 degrees on the Richter scale.
According to the Association presents Volcano Islands (Avcan) on his Facebook page, "Current Volcanic Islands'," the most remarkable increase in tremor imply an increased flow of magma, which by cavitation induce and produce the vibration observed both in seismographs, and by the population of the Restinga "
As shown in the picture accompanying this information is recorded tremor in El Hierro shows a much higher intensity than the tremor that registers Gran Canaria throughout the day on Friday.

IGN this morning recorded two earthquakes of 3.5 and 3.9 degrees - Eleven families evicted - The Pevolca meets at 12.00 to assess the situation after the 4.4 earthquake yesterday - The Roquille remains open under surveillance
EFE Residents of the Canary island of El Hierro have felt two earthquakes today, with magnitude of 3.5 and 3.9 degrees on the Richter scale were recorded at 09.05 and 09.44 hours reported by the National Geographic Institute (IGN) in its website.
These two earthquakes have occurred northwest of the town of Frontera El Hierro in the north of the island, and both have been found to twenty kilometers deep, said the National Geographic Institute.
Of the fourteen earthquakes have been recorded today by the National Geographic Institute thirteen have been found in waters near the town of Frontera and one in El Pinar, this town in the south of El Hierro.
The registered southwest of El Pinar occurred at 00.16 with intensity 3.6 on the Richter scale and seven miles deep.
These earthquakes have been recorded after yesterday one of 4.4 magnitude on the Richter scale would lead to close again Roquille The tunnel, which connects the town of Frontera, Valverde.
The landslides that occurred during this earthquake also led authorities to evacuate homes in the neighborhood eleven stitches, in the town of Frontera.

In the south, at La Restinga, where last October 10 a mouth opened in a fissure eruption by magma found, the material began to precipitate out more to the point where it opened, at least two eruptive new mouths .
In the north, in Frontera, The shock arrived at 20.36 hours with an earthquake that could be felt even in La Gomera and Tenerife.
earthquakes form two distinct groups in terms of the depth of those concerns. On the one hand, one group would be between 20 and 25 km depth while the closest to the surface would be between 10 and 15 kilometers. According to scientists, still too far to think of an impending eruption, even though an earthquake like last night can startle people.

The bubble of La Restinga is reactivated and magmatic material ejected Monday November 7, 2011
The bubbling back with force to the volcanic spot of the Sea of calms. The sea water on the volcano is 11 degrees warmer
LPROVINCIA.ES / Reuters The spot is in the process of boiling. About 10.50 am on Monday, the bubbling began intensively in the Sea of Calm. As reported by Pedro Guerra, Special Envoy of the Province / DLP to El Hierro, the diameter of the spot off the coast of La Restinga is higher than yesterday and this more active.
In addition, the bubble in the spot has begun to expel material bubbling magma and has gained strength.
Abnormal temperatures. Scientists at the Institute of Technology and Renewable Energies (ITER) in Tenerife have detected a difference of more than 11 degrees Celsius from the temperature of water in the Sea of Calm and south of La Restinga, which shows the underwater volcanic eruption El Hierro.
As indicated in a statement today Cabildo de Tenerife, which owns the ITER, the observations yield the greatest temperature anomalies associated with the most obvious surface manifestation of the underwater eruption was recorded south of La Restinga, El Hierro
Specifically, the difference in temperature at the surface marine environment south of La Restinga using thermal imaging cameras in position is the largest air mobile detected so far: more than 11 degrees Celsius.
Water temperature in the surface environment of the Sea Calm, which is not affected strongly by the eruptive activity, has been 23.9 degrees Celsius, while recording the water temperature in the area where the event is observed most obvious shallow submarine eruption reaches the 35.3 degrees Celsius.
This temperature difference in the surface environment of the Calm Sea clearly reflects a major heat flow as a result of submarine eruption, he adds.
Measurements were made yesterday with the help of Helicopter Service of the Guardia Civil in the framework of a collaboration between the Institute of the Canary Islands and volcanological Air Sector Civil Guard on the islands to strengthen the geophysical program (thermometry and thermography ) for volcanic surveillance.

The CO2 emission rate in El Hierro is 3.5 times the normal average Sunday November 6, 2011
The INVOLCAN confirmed that the rate is the highest recorded since the beginning of the volcanic crisis. The diffuse emission of carbon dioxide is one of the parameters of a volcanic eruption precursor
The registration of the diffuse emission of carbon dioxide (CO2) by the volcano island of El Hierro from July 21 to date ranges from 331 to 1218 ± 16 ± 46 tonnes per day. Following the work of diffuse emission of carbon dioxide (CO2) made by the group El Hierro volcanological ITER since 1997, now within the non-tip, has been established that the average value of the diffuse emission dioxide (CO2) by the volcano island of El Hierro is 345 tons per day. On October 6, 2011 and prior to the submarine eruption occurred southwest of La Restinga diffuse emission rate of carbon dioxide (CO2) reached 990 ± 49 tons per day, an emission rate 2.8 times higher than average normal. Recent results show that the emission rate is about 3.5 times the normal average.

Soar CO2 levels in El Hierro - CANARIAS Thursday November 10, 2011
The maps made by scientists at the Ramon Margalef show rapid growth of the submarine volcano of El Hierro. Only in the last four days, the volcano has issued nearly 5.5 million cubic meters of material
CO2 levels have skyrocketed in El Hierro in the last hours. If last week's rate of emission of carbon dioxide and was 3.5 times higher than normal, with more than 1,200 tons per day around the island building, yesterday the figures identified by scientists at the Institute of the Canary Islands Volcano (non-tip) already exceeded the 1,400 tons per day in a place where the emission is normal average of 340 tonnes. Over 900 tonnes of CO2 per day is considered an abnormal emission of carbon dioxide.
CO2 is the first gas that emerges from the depths in a volcanic eruption and could mean that the magma moves with intensity in search of an exit. Normally, the release of CO2 is a warning of a possible eruption.
RAMÓN MARGALEF. The team of the Spanish Institute of Oceanography (IEO) on board the ship Ramon Margalef, has observed the rapid growth of underwater volcano of El Hierro by maps made on different days.
In the first image on the left shows the morphology of the area on October 24, 14 days after the eruption began and the second represents the same area four days later and it can be seen considerable growth both cone and the volcanic casting.
By overlaying the two maps, the researchers were able to estimate that only in these four days the volcano issued nearly 5.5 million cubic meters of material

Despite being classified as a “minor” (menor, in Spanish) eruption, Chile’s Puyehue Cordon-Caulle Volcano continues to pump out large amounts of ash. This natural-color satellite image shows the pale plume blowing to the northeast of the active vent. According to SERNAGEOMIN, the Chilean National Service of Geology and Mining, ash rose to a height of 5 kilometers (3 miles), and blew as far as 300 km (190 miles) from the volcano. Wide-area satellite images show the full length of the plume, and ash covering the Argentinian plains to the east of Puyehue Cordón-Caulle.
This image was acquired by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite on November 4, 2011.

Blanco has said "winning in an eruption probability in the Gulf in the Sea" and does not exclude the possibility of an eruption on land, although this argument seems even more remote.
IGN director said scientists displaced in the zone do not rule out earthquakes of magnitudes greater than 4,5 degrees. Blanco also notes that during the day today have not been observed in surface phenomena but stresses that "the volcano is still emitting material in La Restinga".

There is plenty of magma deep in El Hierro as to think that the volcano looking for a way out in a place other than La Restinga. If at first it was thought that under the crust would be about fifty million cubic meters of magma, new calculations suggest that low iron can be up to a cubic kilometer of magma, that is, one billion cubic meters, that feed two different processes placed horizontally, one at a depth of between 20 and 25 km and another at a height of 10 to 15 kilometers. The most likely theory is now that they are independent, but may join at some point. Even recharging magmatic material from the depths could generate an eruption last considerably over time, can that for over a year.
The surface water pH has also changed, and has gone from a rate of 7.97 to 5.45 surface to five feet deep. "This decrease of three units of PH is that the media is supporting an acid concentration of a hundred thousand times higher than normal."

According to NASA, which imaged the volcano using its Terra satellite, Nyamuragira last erupted in January of 2010. Even though lava flowed more than 21 miles during the eruption, the flow stayed within the park. The ash from the volcano, however, contaminated drinking water in area springs.
In 2002, the nearby Nyiragongo volcano destroyed a large portion of Goma, a city in the eastern part of the country.

A new earthquake on the Canary Island of El Hierro at 8,36pm on Friday evening, resulted in evacuating 11 homes in the Las Puntas area, and once again closing the Los Roquillos road tunnel. Some rockfalls were caused by the tremor, which was located off the coast of Frontera at a depth of 22 kms. It’s the biggest quake of more than 11,000 tremors to have hit the island since July. As a precaution, the Canary Island Government, closed the road tunnel overnight. It’s the main road between Frontera and Valverde, and was reopened on Saturday morning. Experts say the volcanic fissure is moving slowly towards the island, now at a distance of 1,800m, although they insist this was expected and the situation remains safe. Even so it is reported that half the population of La Restinga have now left their homes.

These enrichments are stressed about 100 meters deep in vertical geochemical profiles closer to the bubble located south of the Restinga as a result of the depth of the submarine eruptive mouth, the magnitude of volcanic-download-magmatic hydrothermal and ocean current predominant, according to a statement of the Cabildo of Tenerife.

El Hierro volcano - The volcanic tremor measured at El Hierro remains at very high levels, beaches from Puerto Naos until La Restinga will be closed to the public because of an accumulation of toxic gases
The volcanic tremor measured at El Hierro remains at very high levels and in sharp contrast to visible activity, feeding speculations and fear about new volcanic vents opening up somewhere on or near the island. Some fear such a new vent could be located in the El Golfo Bay, near Frontera, since most of the (deep) earthquakes in recent days are concentrated beneath the northern sector of the island. However, so far, these earthquakes are very deep (ca. 20 km) and do not point towards an immediate eruption in this area, rather are intrusions of dykes in the upper mantle beneath the island. At La Restinga at the southern tip of the island, we could observe a slight increase in activity from the submarine vent ca. 1 km off the coast today: every 15-30 minutes, brownish plumes of water could be seen upwelling, flattening the ocean surface and somtimes producing dark stretches of floating mud(?) and foam (not steam!) in a circular area around the vents. The Instituto Volcanológico de Canarias (INVOLCAN) has been recording highly elevated levels of Helium and CO2 gas dissolved in the water around La Restinga, another sign that the submarine eruption is still in progress.
PEVOLCA, the committee of Emergency services, Scientists and Authorities has decided that the beaches from Puerto Naos until La Restinga will be closed to the public because of an accumulation of toxic gases. La Restinga has no problem as it is more an open space according to the scientists. We regularly display the La Restinga air quality, which was indeed good this morning.
PEVOLCA also said that the 4 km radius in the Las Calmas see remains closed to navigation. Only the Guardia Civil and both Oceanographic ships are allowed in the eruption waters.
