"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

JULY 1, COLOMBIA, NEVADO DEL RUIZ VOLCANO

Colombia volcano erupts, prompts evacuations

Colombia evacuated people from communities close to the Nevado del Ruiz volcano after an eruption on Saturday that spewed smoke and ash from its crater, bringing back memories of avalanches that in 1985 buried tens of thousands under rocks.

President Juan Manuel Santos said on his Twitter account that the area around the Nevado del Ruiz, in the central spine of Colombia's Andean mountain range, had been put on red alert and people should leave the area.

Even as volcanic activity began to subside, emergency services urged 4,800 residents in Caldas and nearby Tolima province to get to safety, according to Carlos Ivan Marquez, who heads the security effort. The volcano is about 110 miles west of the capital Bogota.

Jun 28 : El Hierro Volcano : Green and Yellow alert – 77 earthquakes since midnight UTC

 

Update 28/06 – 08:45 UTC
- New Rapid and Ultra-Rapid GPS deformation data from Prof. Sagiya from the University of Nagoya, Japan show a further increase in deformations at the FRON and PINA stations. Other stations like JULA, REST and SABI remain  unchanged. VALV station shows only a horizontal deformation. IGN does also follow these deformations but has decided to stop publishing them (in 2011, these data were part of the El Hierro public site and refreshed with a delay of 1 to 2 days).  Deformations are one of the many parameters volcanologists are following to predict eruptions and possible changes in the volcanic process.

Update 28/06 – 07:55 UTC
- At least the people of El Hierro must have had a good night sleep as the strength of the earthquakes decreased seriously the last 7 hours. But … only the strong earthquakes were more or less silent at night.
- So far today IGN has listed 39 earthquakes since midnight,  a little less than the preceding days, but still a high number.
- Harmonic Tremor has restarted strongly since 05:35 this morning, showing us that the volcanic process is still continuing strongly. As we have experienced the last couple of days, the current HT may refer to a new migration of the epicenters
- The strongest earthquake since midnight was a M2.8 earthquake. NO earthquakes since midnight have been marked as felt by the people. At ER we think that Felt or no felt indications are far from reality as most people do not indicate slight tremors anymore after having experienced stronger ones. Aftershocks in general are less documented. Only nations like Japan, USA and New Zealand are drilled to report whatever they have felt.
- The depth did not show a lot of difference since midnight with values in between 17.6 and 22.9 km
- The epicenter of the earthquakes since midnight remains the El Julan – La Dehesa area of the island
- We certainly expect more earthquakes to come today as the process continues in full strength.
- What can change the process fundamentally ? Our readers should watch the following elements in the current process with more focus than the rest : Depth of the earthquakes (changes towards a depth of 15 km or less can be triggers of new events, sudden change in the strength of the earthquakes,  the locations of the epicenters (these locations are important in relation to the conduits of the recent eruption)

- Another very active day with a lot of earthquakes which have been felt by the people. The strongest so far this year was a M4 at 18:55 UTC.

Colombia Closes Another Airport Due to Volcanic Ash (June 20) -

http://online.wsj.com/article/BT-CO-20120620-710884.html

Colombia's government has closed a second airport after the Volcanic Ash Advisory Center in Washington issued an ash cloud advisory for the Nevado Del Ruiz Volcano, which Colombian authorities have been saying for weeks is probably getting ready to erupt.

An official with the civil aviation authority Aerocivil said the Matecana Airport in the city of Pereira was closed Wednesday "as a precaution" due to continued ash clouds in Colombia's central, coffee-growing region, located just west of the volcano. The nearby Nubia airport in Manizales has been closed since the beginning of June after the Ruiz Volcano began rumbling and spewing gas and ash.

Hundreds of flights have already been canceled, suspended or diverted due to closing of the airport in Manizales.

Airlines affected by the airport closures include Avianca, the main carrier in the airline group AviancaTaca Holding SA (PFAVTA.BO), Lan Colombia, part of the Chilean flagship carrier LAN Airlines SA (LFL, LAN.SN), and Copa Colombia, part of the Panamanian airline group Copa Holdings (CPA).

For the past few weeks, Avianca and Lan Colombia had been flying their Manizales-bound passengers to Pereira, then shutting them by bus to their final destination. A representative at Avianca reservations department said the new plan is to send all Manizales and Pereira passengers to an airport in the town of Armenia, and then put them on buses.

Last week, Avianca's press office said the costs to the airline stemming from the volcanic ash have been "significant," but declined to disclose a dollar-figure estimate. Representatives at the press office were unavailable for comment Wednesday.

JUNE 23, JAPAN, MT.FUJI VOLCANO

2.8M EQ UNDER MT.FUJI VOLCANO

A 2.8 magnitude earthquake was reported under the Mt. Fuji volcano on the 24th of June. Mt. Fuji last erupted in 1707, but the volcano began showing signs of growing unrest this year - indication it is waking up from its long slumber as we reported. On June 20, 2012, a rare anvil or hat-shaped cloud appeared near Mount Fuji after a strong typhoon swept through Japan. The cloud, called “tsurushi-gumo,” or hanging cloud, was seen on Wednesday morning. The phenomenon occurs when winds around Mount Fuji become strong, or after tropical storms. But experts say such clouds rarely appear at this time of the year. The cloud disappeared after about 30 minutes when the sky became overcast. Source1, Source2

Increased Seismic Activity in Iceland’s Katla Volcano ICELAND
21.06.2012

Increased seismic activity was detected in Mýrdalsjökull glacier in south Iceland, under which the volcano Katla lies, last night. Twenty-six minor earthquakes were picked up by sensors, all of which had their epicenter within the Katla crater.

A seismic activity expert on watch at the Icelandic Meteorological Office informed ruv.is that the earthquake swarm had started at 1 am and continued through 5 am.

However, there is no reason to be concerned about an imminent volcanic eruption or glacial outburst in Katla. The earthquakes were all shallow and originated in seismic activity in the geothermal system.

Nevado del Ruiz Volcano in Columbia Spews Ash and Gas (June 16) -

http://www.bbc.co.uk/news/world-latin-america-18481694

People living on its slopes said they had heard "strong, strange noises" coming from the summit of the 5,346m-high mountain on Friday and Saturday.

Officials say an orange alert first declared three weeks ago is still in place for areas near the summit.

Officials have distributed 30,000 face masks to residents living in areas affected by ash from the volcano.

The airport in the nearby town of Manizales, in central Colombia, has been closed since the end of May, and will remain so until the volcano ceases to emit ash, officials said.

The Volcanic Observatory in Manizales said the plume of ash and gas had risen to a height of 2,000m (6,500ft) on Sunday.

Scientists at the observatory warned there was a risk of an eruption "within days or weeks".

Some 150 families have been evacuated from the banks of the rivers which flow down the volcano, as they were deemed to be most at risk.

INDONESIA'S MOUNT GAMKONORA UNLEASHES 3000 METER HIGH ASH CLOUD

Hundreds of residents in northeastern Indonesia fled their homes on Wednesday after a brief eruption at Mount Gamkonora, spewing towering columns of ash and smoke and prompting officials to raise the volcano’s alert level to the second-highest state. The 1,635-meter (5,364 feet) tall volcano, which is located on the west coast of Halmahera island in the Maluku Islands and is part of North Maluku province, began to erupt on Wednesday afternoon and sent thick ash clouds up to 3,000 meters (9,842 feet) high, although no lava flows were seen. The Antara news agency reported that hundreds of residents living on the volcano’s slope evacuated the area following the eruption......Source
