Volcano watch
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

Volcanic Eruptions Continue on Indonesia's Mt. Lokon (Dec 8) -
http://www.thejakartaglobe.com/news/north-sulawesis-mount-lokon-ent...
Mount Lokon, near the North Sulawesi town of Tomohon, entered its second day of eruption on Friday, belching heaps of ash and smoke into the atmosphere.
“People are asked to remain alert and not conduct any activities within a 2.5 kilometer radius around the Tompuluan crater of Mount Lokon,” said Farid Bima, who heads the volcano monitoring outpost near the mountain.
The 1,579-meter-high volcano first erupted at around 5:18 p.m. on Thursday, sending a column of ash and smoke that reached some 3,500 meters high.
The ash fell mostly on the southeastern slope of the volcano.
Farid said that so far there had been no report of casualties or damages, and reiterated that the alert status of the mountain was still at “ready,” or two rungs above normal and one below full eruption.
Mount Lokon has demonstrated rising volcanic activities since mid-year, he added, and has been undergoing a series of small and large eruptions.
Tomohon Mayor Jemmy Eman announced on Friday a 2.5 kilometer-radius danger-zone and also prepared areas to shelter people if any evacuations needed to take place.
However, he said there was no need for people on the upper slopes of the mountain to be evacuated, since the eruptions so far were not deemed major threats.
“Therefore, there will not be any evacuations yet,” said Arnold Poli, the city secretary.
An eruption of Mount Lokon last month prompted the evacuation of some 5,000 people from its upper slopes.
Hoyke Makarawung, the head of the North Sulawesi Disaster Mitigation Agency, said that his institution had already readied assistance should any evacuation take place in the areas affected by the discharge.

Earthquake swarms could indicate eruption near Nisyros, Greece (Dec 4)
A seismic swarm of 2000 microearthquakes near the island of Nisyros since 24 November could indicate a start of a or coming of a volcanic eruption near Nisyros.
The quakes are located between the area of Simi Island (Greece) and the Bozburun peninsula of SW Turkey: click here for a map and list of quakes.
Information is still scanty, but seismic signals from this possible eruption are very similar to those recorded from current volcanic eruptions.
If an eruption is taking place, it would form a new submarine volcano near Nisyros.
No proof has yet been found to prove that an eruption may be taking place. Some sources think the swarm may be tectonic (as the Aegean sea is very seismically active). The VolcanoDiscovery alert will be kept at Green until further evidence is found.

Santiaguito Volcano Erupts in Guatemala (Nov 29) -
The Santiaguito volcano, in western Guatemala, erupted today with “very strong,” with the release of smoke and ash at high altitudes, so the agency has recommended Meteorology restrict air traffic in the area.
So far there is no need for an evacuation of the villages closest to the volcano, which is located about 227 kilometers from Guatemala City.
The director of the National Institute of Seismology, Volcanology, Meteorology and Hydrology (Insivumeh), Eddy Sanchez, reported that the activity of the volcano at 2,550 meters, and located in the department of Quetzaltenango, started at about 5.30 local time (11.30 GMT ). Sanchez added that the sand and volcanic ash is dispersed within at least a 4 kilometers radius of the volcano. “There is a crater collapse, pyroclastic flows, and notice has already been given to Civil Aviation to restrict air operations in that region,” said the director of the local radio Insivumeh. He also reported they warned the National Coordinator for Disaster Reduction (Conrad) to take the necessary precautions.
Sanchez said the eruption of Santiaguito will last for several hours and urged people to stock up surrounding drinking water because the sand and volcanic ash can contaminate streams that may be harmful to health. The sand and ash has fallen in populations of the departments of Quetzaltenango and Retalhuleu, where they can be affected coffee plantations, according to Sanchez. The volunteer fire departments of these two departments have declared orange alert or prevention, while experts Conrad Insivumeh and keep a constant eye on the evolution of the eruption.

Kamchatka Volcano Eruption Destroys Science Camps (Nov 30) -
http://en.ria.ru/russia/20121130/177832742.html
Lava flows from the slope of erupting volcano Plosky Tolbachik in Russia's Far Eastern Kamchatka Peninsula have destroyed two nearby scientific camps, a local branch of the Russian Academy of Sciences said on Friday.
The 3,085-meter Plosky Tolbachik, which is part of a volcanic complex located 343 kilometers from the region's capital of Petropavlovsk-Kamchatsky, erupted on November 27 for the first time in 36 years.
The two camps were located 10 kilometers from the volcano.
The eruption has been already assigned a Red Code status as the volcano is throwing clouds of ash to the height of 3,000 meters with the potential for ash explosions up to 10 km.
Residents of nearby villages have been advised not to leave their homes as massive ash falls in the area are filled with toxic sulfur fumes.
The Plosky Tolbachik erupted 10 times since records began in 1740, with the most notable eruption in 1975, commonly known as The Great Tolbachik Fissure Eruption. Soviet scientists successfully predicted the eruption because it was preceded by a series of earthquakes.
The 1975 eruption dramatically changed the local landscape and became an ecological disaster as the volume of lava and ashes emitted by the Plosky Tolbachik was the largest in recorded history of Kamchatka.
There are more than 150 volcanoes on Kamchatka, 30 of them active.

New Zealand Volcano Mt Tongariro Erupts Again (Nov 21) - UPDATED
Nov 22 Update:
A New Zealand volcano that neighbors a mountain best known as Mount Doom of the Lord of the Rings films (Mount Ruapehu, also set to erupt) has rumbled back to life.
Mount Tongariro, situated in a remote part of the country's North Island, erupted for five minutes on November 21, spewing clouds of ash 2.5 miles (4 kilometers) high.
Mt Tongariro Erupts (Nov 21)
A massive plume of ash can be seen coming from the mountain and an operation is underway to get people off the Tongariro Crossing.
The official GNS Science monitoring service issued a potential threat alert after the eruption at the North Island volcano, which became active in August this year after lying dormant for more than a century.
GNS Science duty volcanologist Nico Fournier told APNZ the eruption happened about 1.20pm.
Wellington Airport spokesman Greg Thomas said no flights had been affected yet, however that could change and the situation was being monitored.
Up to 70 Napier School children were reported to be two hours into a tramp on the Tongariro track.
Two bus drivers from Nimon and Sons, who took the children up to the mountain, had reported back to their base that they could see a plume 2km high, a spokesman said.
Lake Rotoaira resident Robyn Bennett said there was a big, black ash cloud over her house, which was about a kilometre from the eruption site.
"It's just blew her stack," she said.
She said the air smelled of sulphur.
"It's hard to breathe if you go outside, it's pushing out quite heavily." Bennett said she didn't hear the eruption but it looked like a new vent had formed in front of a previous eruption crater. The ash cloud was moving east towards Napier and Taupo.
Ann Lambert, owner of the Rainbow Motel at Tokaanu, near Turangi, said she had not been aware of any noise, unlike the previous time Tongariro erupted when there had been a "huge loud noise".
"We weren't aware it had happened. We just looked up and saw it," she said.
HISTORY REPEATS
This is the second eruption this year. The Te Maari crater erupted on August 6, the first time in more than 100 years.The eruption, on August 6, widened and deepened the crater and reactivated vents which had been covered up in the 116 years since it last erupted in 1896.
Ruapehu has also been active recently but has not erupted. Pressure was building under the volcano and there was an increased likelihood of an eruption, GNS said last week.
A series of earthquakes rattled the ground beneath Tongariro in the weeks leading up to the August eruption and another series of quakes have shaken the ground beneath Ruapehu in the last few weeks.

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. AriasAccess 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.
