"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

RUAPEHU ERUPTION WARNING FOR NZ CLIMBERS (NEW ZEALAND, NOV 16)

 

New Zealand authorities are urging climbers and hikers to stay away from the summit of Mt Ruapehu after warnings the volcano could erupt.

A summit hazard zone - the area within two kilometres of the centre of Crater Lake - should be avoided, the Department of Conservation's Ruapehu area manager Jonathon Maxwell said on Friday.

The warning did not affect nearby Mt Tongariro or the popular Tongariro Alpine Crossing, but people should be aware of an increased possibility of lahars (mudflows containing volcanic matter) in streams on the Round the Ruapehu Mountain track.

On Friday morning, GNS Science said pressure was building under Mt Ruapehu and there was an increased chance it will erupt.

The aviation alert level around the central North Island has been raised to yellow - suggesting unrest above background levels - but the volcanic alert level remains unchanged at "signs of unrest".

GNS Science vulcanologist Steven Sherburn says the changes make scientists believe eruptions are more likely in the coming weeks to months.

Volcanic Activity November 1 - 2:

1.  An increased number of earthquakes can be noted beneath Askja volcano in Iceland during the recent days, and the tremor signal is elevated as well, although far from alarming levels. The volcano is certainly one to watch out for.

2.  A strong SO2 plume is visible from Nyiragongo. The Goma Volcano Observatory has reported continuous ash emissions. This could suggest a new eruptive phase at the volcano has begun.

3. The seismic swarm in the Tjörnes Fracture Zone north off Iceland that had started nearly 2 weeks ago continues as well although at somewhat reduced pace. Quakes are contentrated in 2 main areas at the western and eastern sides of the fault system.

4.  Elevated seismic activity including a swarm of quakes in mid October and ongoing slight deflation continued at Yellowstone caldera volcano during October. There are no signs of a possible reawakening in a near future.

5. Popocatépetl's activity has been showing a weak increasing trend with more than 2 exhalations per hour during 30 Oct - 1 Nov. Some emissions probably contained small amounts of ash. Glow from the crater remains visible at night, indicating that the lava dome continues to grow slowly there.

6. Fuego volcano in Guatemala has mild infrequent strombolian explosions and continues to feed its lava flow, which however has decreased to 200 m length.

7. The lava flows from Santiaguito lava dome were reported calm this morning. Few weak explosions are sometimes observed from the dome.

8. Pacaya volcano is steaming only, but continues to show some elevated seismic activity.

9.  Seismic swarms of low energy continue to occur at Cumbal volcano in Colombia. Nevado del Ruiz volcano continues to emit significant amounts of steam and gas, and sometimes small amounts of ash. Galeras volcano has had small intermittent ash explosions recently. The country's other volcanoes currently on yellow alert have not shown significant variations in their activity during the past week.

10.  MODVOLC detected a hot spot at Pagan volcano in the Marianas on 31 Oct, the first time since August 2012. According to USGS, the volcano continues to show only steaming, but it cannot ruled out that the new thermal anomaly might be caused by near-surface lava.

11. Alaid volcano (Northern Kuriles, Russia) continues to show a thermal hot spot as well. The volcano is not monitored on ground.

12. Raung volcano in East Java might have been erupting on a small scale already since 19 Oct. A video from a visit at the local volcano observatory shows strong seismic activity, but no visible plumes rising from the volcano's summit.

13.  An explosion from Kizimen volcano in Kamchatka today produced an ash plume rising to 17,000 ft (5.2 km) altitude, VAAC Tokyo reported.

Poás Volcano rumbles, spits ashes

Posted: Monday, October 29, 2012 - By L. Arias

Access to one of Costa Rica's most popular national parks remains open to tourists.

Experts from the National Seismological Network are keeping the volcano under surveillance.Courtesy of RSN

The Poas Volcano early Sunday awoke residents of the province of Alajuela with a strong rumble.

At about 1 a.m., the volcano’s crater ejected mud and ash more than 500 meters into the air. Ashes traveled hundreds of meters around the national park, rangers reported.

Although the volcano is frequently active, this kind of strong explosion has not been recorded since 2006. Experts said the activity was normal, but they will continue monitoring the volcano.

Poás Volcano National Park will remain open to tourists while experts determine if there is any risk to visitors.

Kuril Islands Alaid Volcano Awakens (Oct 25) -

http://english.ruvr.ru/2012_10_25/Kurils-Alaid-volcano-wakes-up/

A volcano in Russia's Far East has begun spewing ash with the giant ash cloud rising to an altitude of up to 700 meters.

The Alaid Volcano is the tallest and northernmost volcano in the islands, with a crater which is approximately 1.5-km-wide.

The first signs of activity were recorded on October 7th when thermal anomalies were observed a cloud of steam appeared.

Volcanologists are issuing warnings regarding the likelihood of an eruption of ash emissions which may reach a height of 10-15 kilometers above sea level.

UNDERWATER VOLCANO ERUPTS CLOSE TO MINAMI ISLAND, JAPAN, COULD CREATE A NEW ISLAND (OCT 16)

An underwater volcanic eruption was detected Wednesday morning close to Minami-Iwoto island in the Pacific Ocean and an expert speculated that the eruption could form a permanent island. A coast guard vessel spotted a white plume of smoke rising from the sea about three miles north-northeast of the island. It was the first time since July 2005 that volcanic smoke had been detected in the area, which is located about 745 miles south of central Tokyo. According to an announcement by the 3rd Regional Coast Guard Headquarters of the Japan Coast Guard, based in Yokohama, the volcano spewed ash and smoke about 100 meters into the air, and the surrounding sea area changed to a yellowish-green color while other parts became a cloudy gray. According to the Meteorological Agency, the volcano, known as Fukutokuokanoba, has erupted seven times since 1904, when its activities were first recorded. On three occasions, land masses were formed, but all later sank below the waterline. Tokyo Institute of Technology Prof. Kenji Nogami, an expert in geoscience, said: "In the 1986 eruption, a new island appeared after lava accumulated. The island was washed away by waves, but seabed upheaval reduced the water depth to 22 meters in 1999. It's possible that this (recent) volcanic activity could form a permanent island."

HIGHEST VOLCANO IN EURASIA STARTS ERUPTING (RUSSIA, OCT 15)

The highest active volcano in Eurasia, Klyuchevskaya Sopka has started to erupt, officials with the Institute of Volcanology and Seismology said.

On the night of October 15, there was light seen over the summit of the volcano indicating a blowout of lava in its crater, Vesti.ru reports. Experts believe the release of ash to the height of 6 feet above sea level may start any moment. Lava flows on the slopes of the volcano are also expected.

Yellow aviation color code has been assigned to the volcano to warn about the potential danger that the volcanic ash and gases may pose to aircraft engines. Nothing has been said about the possible threat to human settlements. The nearest settlement is 30 kilometers far from Klyuchevskaya Sopka.

The last eruption of Klyuchevskaya Sopka took place from September 2009 to December 2010. In June this year, the giant began to wake up again. Klyuchevskaya Sopka is located 360 km north-north-east off Petropavlovsk-Kamchatsky. The height of the mount is 4,750 meters above sea level.

Mount Lokon in Indonesia Erupts Again (Oct 7) -

http://www.vancouversun.com/news/Volatile+volcano+erupts+again+nort...

Mount Lokon in North Sulawesi province erupted Sunday, spewing smoke and ash that caused muddy rain to fall in nearby villages, an official said.

The volatile volcano rumbled as heavy rain fell around its cloud-covered crater, local monitoring official Farid Ruskanda Bina said.

He said the sound was heard 5 kilometres (3 miles) away but the height of the eruption was not visible.

The ash made the rain thick and muddy in six villages, Bina said.

"Soldiers are distributing masks to the villagers," he said.

There was no plan for evacuations because the nearest villages are beyond the danger area, he said.

More than 33,000 people live along the fertile slopes of the 5,741-foot (1,750-meter) mountain.

Loud, Thumping Noises Heard

http://www.cnn.com/2012/10/07/world/asia/indonesia-volcano/index.ht...

Loud, thumping noises were heard at a monitoring post 6 kilometers (3.8 miles) from where Mount Lokon erupted around 2:05 p.m. (2:05 a.m. ET) Sunday, said Sutupo Purwo Nugroho of Indonesia's National Disaster Mitigation Board, as reported by the official Antara news agency.

The volatile activity continued after that, though authorities could not immediately ascertain how many additional, separate eruptions had occurred.

"Right now, there are still eruptions, but they could not be observed as the volcano is covered by haze," said Nugroho.

Those living within 2.5 kilometers of the volcano, which is in the Pacific island nation's North Sulawesi province, are being told not to carry out any activity, according to Nugroho, who heads the mitigation board's data and information center.

The volcano has been active since last Friday, with some eruptions spewing ashes 1,500 meters into the air. One day earlier, officials issued an early warning to residents -- yet Mount Lokon was still categorized as idle until Sunday, as it is now on alert status.
