"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

27th August 2014 20:50 - info from a surveillance flight

Scientists from IES and IMO on a flight to Vatnajökull tonight discovered a row of 10-15 m deep cauldrons south of the Bárðarbunga caldera. They form a 6-4 km long line. The cauldrons have been formed as a result of melting, possibly a sub-glacial eruption, uncertain when. Heightened tremor level/volcanic tremor has not been observed on IMO's seismometers at the moment. The new data are being examined.

New fractures in Holuhraun next to Dyngjujökull caused by recent earthquakes

“Hard to Explain what Happened if not Caused by an Eruption”

August 27, 2014 23:14

Rifts, about four to six kilometers long, have formed in Vatnajökull outlet glacier Dyngjujökull northeast of Bárðarbunga, as reported by RÚV, visir.is and the Icelandic Met Office. Small calderas have formed in the glacier and it cannot be ruled out that an eruption has started.

According to the Civil Protection Department, there is no indication of a flood yet, but the department's director Víðir Reynisson told RÚV television just now (at 10.20 pm) that it would be hard to explain what has occurred if not caused by an eruption.

Everyone concerned is very cautious in light of the false alarm on Saturday, but the new calderas are thought to have been formed by heat from below.

We will try to update the news as soon as reports arrive from the Icelandic Met Office and others.

According to the Icelandic Met Office, approx. 50 million cubic meters of magma have been added to the current intrusion. This corresponds to an average of approx. 500-600 cubic meters a second!
Seismic activity remains high with no signs of weakening. If the intrusion breaches the surface, the most likely scenario seems to be a fissure eruption at the present location of the northern end of the dyke, i.e. immediately north of the Dyngjujökull glacier.

http://www.volcanodiscovery.com/bardarbunga/seismic-crisis-2014/upd...

The earthquake this morning at the north/northwestern part of the caldera at 6 km depth at 01:26 UTC could have been the biggest in the current swarm. Estimated magnitudes range from 4.1 (IMO) to 5.7 (USGS).
The magma intrusion (dyke) north of Dyngjujokull is still migrating and stretches now approx. 10 km outside of the glacier.
It will be interesting to see what happens when it reaches the area of the Asjka fissure swarm. A possibility could be that older dykes from that one stop the propagation of the Bardarbunga intrusion, another that it activates Askja as well.

26th August 2014 17:53 - from geoscientist on duty

Just under 900 earthquakes have been detected by the network since midnight, somewhat fewer than at the same time yesterday. The intrusive dike is now about 40 km long. Most of the activity has been near the edge of the glacier. An earthquake M4.6 (EMSC M4.4) occurred at 11:56. Reports were received from Akureyri (a town in northern Iceland) that the earthquake was found there. The earthquakes are mostly on similar depth as before, i.e. 8-12 km. A few were larger than M3. Few earthquakes were located in the Bárðarbunga caldera today.

Breaking News: Eruption Started in Dyngjujökull Glacier
August 23, 2014

An eruption has occurred at the site of the volcano Bárðarbunga. At the moment, it is still a sub-glacial eruption, meaning that there is no visible evidence of it, such as a plume or smoke. For now it is beneath the surface of the Dyngjujökull​ icecap in the northern part of the Vatnajokull glacier, scientists at the Iceland Met Office say.

There has not been any need to evacuate nearby towns as the eruption is not above the surface, however the area has been blocked off for tourists and the air space in the surrounding region has been restricted.

It remains to be seen what will happen as a result of this preliminary eruption. The area is being closely monitored and the National Commissioner of the Icelandic Police has determined that the level of emergency is now in the red phase. Locals living in nearby towns have been advised to pay close attention to updates. At this moment this is considered a small-scale eruption.

-A small lava-eruption has been detected under the Dyngjujökull glacier.

-The Icelandic Coast Guard airplane TF-SIF is flying over the area with representatives from the Civil Protection and experts from the Icelandic Met Office and the Institute of Earth Sciences. Data from the equipment on board is expected later today.

-Data from radars and web-cameras is being received, showing no signs of changes at the surface.
-The estimate is that 150-400 meters of ice is above the area.

-The aviation color code for the Bárðarbunga volcano has been changed from orange to red.

-Some minutes ago (14:04), an earthquake occurred, estimated 4.5 in magnitude.

ntense earthquake activity continues at the Bárðarbunga volcano – a situation that has persisted since 16 August.

During the last 6 hours the dyke has propagated ~5 km to the north. The rate of earthquakes has increased such that they are happening so quickly that it is difficult for the seismologist to discern individual events. Observed high frequency tremor is interpreted to be caused by the propagation of the dyke.

The land below Vatnajökull glacier has drifted apart by 20 centimeters (8 inches) since the seismic activity and magma flow began in Bárðarbunga volcano, which lies underneath the northwestern part of the glacier, one week ago.

“The continental drift is two centimeters per year, so this is ten times the [natural] continental drift,”

in the one week since the activity began, approximately 5,000 earthquakes have been picked up by sensors, the largest of which was of a 4.7 magnitude and hit shortly before midnight on Thursday. A 3.5 earthquake hit at 6 pm yesterday.

The large quakes are believed to be caused by the magma chamber depressurizing, by the strain from the channel the magma has formed—or both. The caldera appears to be sinking.

According to a model made by the Earth Science Institute, approximately 200 million cubic meters (7.1 billion cubic feet) of magma has been flowing underneath the glacier in the past week. “The volume has doubled in just the last two days,” stated Þóra.

http://www.ruv.is/frett/met-office-25-km-long-dike-formed

A 25 kilometer long dike intrusion has formed, north and east of the Bardarbunga caldera. Intense seismic activity continues there. Strong earthquakes have been detected in the caldera itself, but they are associated with decompression of the magma chamber beneath the caldera.

According to the Icelandic Met office (www.en.vedur.is) there are no signs that seismicity is decreasing. A 25 kilometer long dike has formed in the crust under the Dyngjujokull outlet glacier at 5 - 10 km. depth. Magma is thought to countinue to move along the dyke, possibly branching out at the NE end of the dike.

Several strong earthquakes have been detected in the Bardarbunga itself; the last one, magnitude 3,5, at around 11 GMT this morning, These events are thought to reflect an adjustment of the caldera rim, related to decompression in the caldera since the beginning of the unrest six days ago.

Land displacement measurement with GPS around the volcano show up to 14 centimeter drift since the unrest began, on August 16. Annual drift in Iceland, due to crustal plate movements, is about 2 cm.

„A new GPS station in Kverkfjöll is now running and sending data. Similar seismic instruments were installed by Kverkfjöll yesterday, as well as close to the GPS station at Hamarinn, which was set up two days ago. In addition, two seismic stations set up in Dyngjujökull yesterday are collecting data on site. This work is done in collaboration between IMO, the Institute of Earth Sciences and collaborators in the European FutureVolc research project.“ (Icelandic Met Office).

The evacuation order for the area north of Vatnajokull is still in effect. The area north of Route 1 (including Dettifoss, Hljodaklettar, Asbyrgi) is still open to the general public.

Alert volcano Bardarbunga: 3,500 shocks in a few days [3D VIDEO]
Friday, August 22, 2014

The seismic activity of the volcano Bardarbunga can be explored through a 3D video

showing the series of earthquakes that have affected the area 16 to 20 August 2014. images clearly show location, depth and date of shocks, ranging from the latest in red, then orange, yellow, light green and green (not given magnitude).

The area has been affected by more than 3,500 shocks and the volcano Bardabunga, buried under the largest glacier in Europe, does that send signals such as earthquakes and explosions threatening.'s More intense shock (magnitude 4.5) in the last 20 years has been recorded on Monday last year, and it is for this reason that Iceland's Civil Aviation Authority has issued the orange alert, the second level of danger.

"The magma is moving," said volcanologist Dave McGarvie who is very focused on the study of the volcano. No one knows exactly what will happen, but according to volcanologist there are various possibilities, including localized flooding (if the emission of lava would melt the glacier), or eruptions more or less relevant. Much depends on the thickness of the glacier and the depth of earthquakes.

Sudden Strong Explosion at Peru's Ubinas Volcano (Aug 21)

A powerful explosion occurred suddenly at the Ubinas volcano yesterday afternoon at 15:36 local time.

The explosion ejected blocks to up to 2 km distance and produced an ash plume that rose to approx. 7-8 km altitude.

The eruption was likely a vulcanian-type event, i.e. caused by the sudden release of pressure as viscous and gas-rich magma had accumulated beneath a solid plug in the vent.

It shows that the eruptive phase at the volcano continues and is capable of producing extremely dangerous explosions.

Iceland Begins Evacuations Around Bardarbunga Volcano (Aug 20)

Iceland's authorities have evacuated an area close to the country's Bardarbunga volcano over fears it could erupt.

The area, which is more than 300km (190 miles) from the capital Reykjavik, has no permanent residents but sits within a national park popular with tourists.

The move came as geologists said about 300 earthquakes had been detected in the area since midnight on Tuesday.

Iceland's Eyjafjallajokull volcano erupted in 2010, producing an ash cloud that severely disrupted air travel.

The national civil protection agency said the decision to evacuate more than 300 people close to Bardarbunga was a "precautionary" safety measure.

"It cannot be ruled out that the seismic activity in Bardarbunga could lead to a volcanic eruption," it added.

On Monday, Iceland's meteorological office raised its assessment of the risk level to the aviation industry from yellow to orange.

The orange alert, the fourth level on a five-grade scale, indicates that a volcano is showing "escalating unrest with increased potential of eruption".

The Bardarbunga volcanic system is located under the north-west region of Iceland's Vatnajokull glacier.

Authorities say any eruption in the volcano, which sits under an ice cap, could result in flooding of the area north of the glacier.

The volcano was said to be stable on Wednesday but scientists warned that it is big enough to disrupt air traffic over the Atlantic if an eruption does occur.

The Eyjafjallajokull eruption in April 2010 caused the largest closure of European airspace since World War Two, with losses estimated at between 1.5bn and 2.5bn euros (£1.3-2.2bn).

Criticism following the strictly enforced shutdown resulted in the UK's Civil Aviation Authority relaxing its rules to allow planes to fly in areas with a low density of volcanic ash.

Mayon Volcano alert raised

LEGAZPI CITY, Philippines—The alert level over Mayon Volcano has been raised to 2 from 1, the Philippine Institute of Volcanology and Seismology said Friday.

Volcanologist Alex Baloloy, who is based in Lignon Hill Observatory here, confirmed, in a text message, that the alert level has been raised to 2 as of 1 p.m.

Alert level 2 means the volcano is in a state of “moderate unrest” compared to alert level 1 which means a state of “abnormal condition.”

The new alert level has yet to be posted on Phivolcs’ website but its 8 a.m. bulletin when the volcano was still at alert level 1 showed no crater glow was observed over the volcano last night.

Sulfur dioxide (SO₂) flux was measured at an average of 850 tons per day on Monday.

Papua New Guinea's Bagana Volcano Erupting (Aug 12)

Intense activity has been taking place at the volcano during the past days.

A significant ash plume reaching approx. 25,000 ft (7-8 km) altitude has been observed on satellite imagery drifting 100-150 km southwest.

A thermal anomaly is visible on satellite imagery, suggesting that the volcano has entered a phase of significant lava dome growth that produces explosions and/or collapse events that result in ash plumes.

During 6-12 August, DMPGM reported increasing volcanic activity at Bagana volcano. Thin to thick white vapor plumes from Bagana were accompanied on 6, 8 August by reports of rockfalls. On 10 August an ash plume rose to an estimated several hundred meters above the crater drifting SW and W. Moderate ash was reported in Wakovi (6 km W).

Residents were advised to evacuate to Gotana (9 km SW) if ashfall continued. On 11 August the Darwin VAAC reported ash plumes rose to 3 km (10,000 ft) a.s.l. and drifted up to 55 km SW. On 12 August Darwin VAAC raised the Aviation Color Code to Red as ash plumes rose to 7.6 km (25,000 ft) a.s.l. and drifted up to 167 km SW.

Indonesia's Slamet Volcano Spewing Magma 300 Meters High (Aug 10)

Mount Slamet has erupted on ten occasions since August 10.

Local authorities have banned all climbing activities on Mount Slamet in Central Java due to the radical increase in volcanic activity.

Between August 6 and 7, Mt. Slamet emitted fireballs from its crater to a height of between 50 and 300 meters.

Tremors were recorded 21 times on August 6 and it emitted volcanic ash 419 times.

The volcano also produced strong thundering sounds.

Due to this current situation, officials are prohibited from conducting any activity within a 2-kilometer radius of Mt. Slamet.

Mount Slamet straddles the five districts of Banyumas, Purbalingga, Pemalang, Tegal, and Brebes in Central Java, noted the Volcanology and Geological Disaster Mitigation Center (PVMBG).
