"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

Thousands Flee as Mt. Sinabung Volcano Pelts Villages with Rocks (Sept 15)

A powerful eruption at Sumatra's Sinabung volcano forced more than 6,000 people to evacuate their homes.  The 2,600-metre (8,530ft) volcano in North Sumatra province erupted early on Sunday after being dormant for three years, sending thick ash into the sky with small rocks pelting nearby villages.

Thousands of residents living in 11 villages in Karo regency, North Sumatra, fled to traditional meeting halls or jambur and houses of worship after Mount Sinabung erupted early on Sunday.

As of 1 p.m. local time on Sept 15, waves of people continued to flock to several jambur and houses of worship. Some were evacuated by local authorities in military and police trucks, while the remainder fled on their own initiative.

On Sept 16, grey smoke still billowed from the peak of North Sumatra's tallest volcano, carrying ash eastwards. The authorities asked residents to remain alert for more potential eruptions.

Residents who live within a radius of 3 km from the volcano are not allowed to go home,

Around 6,000 people were staying in temporary shelters, including the Sempakata and Taras jambur, the Kabanjahe meeting hall, the Kabanjahe Mosque and the Kabanjahe Karo Batak Protestant Church.

Mt. Sinabung last erupted in August 2010, which was its first in 410 years. Thousands of residents fled, while several people died from smoke inhalation.

Peru Declares State of Emergency After 7 Volcanic Eruptions (Sept 12)

Peru declared a state of emergency Thursday in nine districts threatened by the Ubinas volcano, which has erupted seven times since September 1, spewing harmful gas and ash.

Authorities are distributing masks and have given themselves a 60-day period to relocate villagers from areas where ash is damaging crops and polluting water sources.

The explosions have sent a plume of smoke rising to 2,500 meters (1.5 miles) above the crater, according to volcanologists at the Geophysical Institute of Peru.

The first explosion on the night of September 1 was strong and followed by a series of lesser blasts, seismologist Victor Aguilar of the Geophysical Institute of the University of San Agustin de Arequipa told AFP.

The volcano, in the Moquegua department 1,250 kilometers (776 miles) south of Lima, is the most active in the country.

Since 1550, 25 eruptions have been recorded at Ubinas.

Indonesia's Mt. Lokon Volcano Erupts (Sept 9)

The Mount Lokon volcano spews giant column of ash clouds more than 8,000 feet into the air during a series of eruptions seen from Tomohon, Indonesia. Officials imposed a 1.5-mile danger zone around the volcano and warned residents to remain alert. The eruptions are part of high volcanic activity of Mount Lokon that have been taking place since July 2011.

Mount Lokon in Tomohon, North Sulawesi, erupted again at 6:30 a.m. local time on Monday, spewing volcanic material from the Tompaluan Lokon crater over 1.5 miles high in the air.

“The lava flow reached several northern area villages, namely Pineleng, Tanawangko and Tateli,” said National Disaster Mitigation Agency (BNPB) spokesperson Sutopo Purwo Nugroho in Jakarta on Monday, as quoted by Antara news agency.

Sutopo said the explosion was heard as far away as Minahasa, which is 10 kilometers away from the volcano.

The status of the volcanic activity remains at Siaga or “alert” (level 3), Sutopo explained.

He said Mt. Lokon had erupted tens of times since the alert status was announced on July 24, 2011.

“The Volcanology and Geological Disaster Mitigation Center [PVMBG] has warned local residents and visitors to stay outside and to not go within a 2.5-kilometer radius of the Tompaluan crater,” said Sutopo.

Ecuador's Reventador Volcano Erupts (Sept 6)
Ash emissions and explosions from Reventador are occurring more frequently and have gained in strength, following a phase of less intense activity.

At least one of the recent explosions generated a pyroclastic flow on 5 September on the south side of the volcano.

Karangetang volcano (Siau Island, Indonesia): incandescent lava at summit, alert raised (Sep 5)

A new eruption could be underway at the volcano. VSI raised the alert to 3 (Siaga, alert) on a scale of 1-4, following the observation of incandescent lava at the summit and glowing rockfalls on the eastern side into the Batuawang ravine. Strong degassing generates a plume rising up to 500 m. Satellite images show a hotspot at the summit as well. These observations suggest that new magma has been arriving at the summit where mild strombolian activity is taking place. If this activity increases, the occurrence of dangerous pyroclastic flows is a likely scenario, similar to what happened at Fuego volcano in Guatemala a few days ago.

Large Explosion at Japan's Sakurajima Volcano Damages Cars 4Km Away (Sept 4)
A moderately large vulcanian explosion occurred this morning, producing significant fallout of lapilli and small bombs in several kilometers distance.

Cars parked at the Arimura Lava observatory observation point to the south of the volcano were damaged and windshields broken, at a distance of about 4 km. There are no reports of injuries to people.

The ash plume from the eruption rose to approx. 12,000 ft (3.6 km) elevation, i.e. about 2.5 km km height. In itself, today's explosion is not even among the largest that have occurred in the past months, but the volcano clearly continues to be in a state of elevated activity when seen on a long-term average.

The following webcam time-lapse video shows frequent ash emission and explosions from the volcano today:

In a recent interview with Radio New Zealand, volcanologist Masato Iguchi mentions that the volcano might be heading for a larger eruption comparable to that of 1914:

“The magma level deep within the volcano is back to about 90% of what it was before the 1914 eruption. So we do have to worry about a big eruption in the long term”.

Small ash emission Etna yesterday morning

The emission of ash yesterday, view the Webcam of Milo. Image: INGV

Small ash emission was observed yesterday morning on the NCSE (New East Cone)
http://www.volcanodiscovery.com/etna/news.html

This would likely be the first eruptive activity since the spectacular series of paroxysms in the first months of the year.
It could indicate that Etna is about to wake up again with more activity in the near future.

Ubinas Volcano in Peru Erupts 5 Times in 2 Days (Sept 3)

Ubinas Volcano in Moquegua registered two small eruptions on Sep 1.

A third eruption occurred the following day, and now the volcano has erupted twice more, bringing the total to five eruptions in less than 48 hours.

A number of news outlets have reported that the volcano’s sudden burst of activity has caused alarm in the area, which has been intensified by the appearance of a column of volcanic gases and ash that has reached a height of two kilometers.

The column of ash has deposited residue up to 10 kilometers away from Ubinas. However, Mariño Salazar stated that the ash column does not pose a danger to people or livestock at this time, as the wind is blowing it towards a mostly uninhabited area. Still, Salazar may meet with local authorities on Sept. 4 in order to discuss any necessary actions.

Scientists are investigating the cause of the eruptions.

Lava Flows Increasing at Fuego Volcano in Guatemala (Sep 2)

A phase of increased lava flow activity occurred this morning from about 6 am local time, generating a series of pyroclastic flows that descended several ravines on different, but mostly the southwestern side of the volcano.

The volcano has been in moderate effusive activity for at least the past two weeks, feeding relatively small lava flows on the upper steep slope. A sudden increase in effusion rate seems to have caused the destabilization of the lava flows, generating rockfalls that turned into pyroclastic flows.

The lava flows have quickly increased from previously 200 m to about 2 km length. The surge of magma supply is also suggested by the appearance of strong tremor pulses the previous night.

An ash plume rising as a by-product of the pyroclastic flows was reported to about 12,000 ft (3.6 km) altitude.

Seismic activity close to Mount St Helens- September 2, 2013

USGS geologists have been tracking an unusual sequence of earthquakes in recent weeks near Mount St. Helens. The swarm, which included M 3.7, M 3.4 and M 3.1 events on August 23rd, started on August 2nd with an M 3.1. They are occurring at about 20 km northwest of Mount St. Helens at a depth of about 16 km.

About 120 earthquakes in total have been recorded since the swarm began. People in Battle Ground, Clark County, reported feeling the M 3.7 event on August 23rd, but since then things have tapered off. The last measurable quake was a 0.6 magnitude on August 27th .

Similar activity has been recorded on the south side of Mount Hood, with 16 small earthquakes the largest of which reached M 2.0 on August 26th.

Eruptive activity Suwanose Jima - JAPAN Ryukyu

Since August 26 the number of balletins VAAC Tokyo soared
Of course, this is a signal that something is happening. But we still had to wait for suffisemment of bits of information in order to make a post.

The images of MTSAT-2 and MODIS finally today clearly show the presence of a plume that stretches up to a hundred kilometers away northeast.

Tokyo VAAC indicated in its latest reports that the ashes are walking at an altitude, all modest sum of 1600 m. With a building which rises to 799m, we can already conclude that the height reached by the plume is about 800 m. This estimate of the Tokyo VAAC is confirmed by the images produced by the Japan Meteorological Agency webcam installed on the volcano island close to Nakano-Jima.

The activity had begun on 26 August, but thermal signals, possible precursors, had been captured on 13 August.

Momotombo volcano (Nicaragua): earthquake swarm intensifies

The earthquake crisis has intensified today and developed into a swarm of shallow (around 5 km depth) earthquakes SE of the volcano. INETER reported already more than 30 quakes between magnitude 1-3 today.
There is no official statement available so far, although this might well be a precursor for a possible eruption in the near future. [less]
