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

JUN 8, HAWAII, KILAUEA VOLCANO
LAVA FLOWS ACCROSS COASTAL PLAIN
Over the past week, lava flows on Kīlauea's coastal plain have been persistently advancing towards the ocean, though at a slower pace during a mid-week pressure decrease, increasing over the past day with renewed pressure. The flow front is estimated to be about 2km/1mi from the ocean still, so we await the effects of this renewed pressure at the coast! A series of webcam captures from the USGS-HVO shows the progression of these flows over the past week.
Meanwhile, pressure is still high across other parts of the volcano, with small lava flows and a lava pond increasingly present within Pu‘u ‘Ō‘ō crater (not directly accessible, but glow can be seen from a distance with clear weather), and the summit lava lake within Halema‘uma‘u still at high levels and producing strong glow visible from the Jaggar Overlook after dark. Within this newest crater but still out of sight, there have been spillovers of the lava lake as it continues to overtop its previous high-level banks!
There have been many earthquakes on the south flank of the volcano, seeming to indicate continuing movement and adjustment of this huge landmass in response to this increased pressure -- first manifested as a slow-slip event last week! Source

JUN 8, CHILE, TATARA SAN PEDRO VOLCANO
VOLCANIC UNREST: EQ SWARM REPORTED AT CHILE'S TATARA-SAN PEDRO VOLCANO
This hasn’t entirely been settled, but the latest report in 24Horas.cl has the SERNAGEOMIN ruling out any volcanic origin to the spate of earthquakes near San Pedro-Tatara (San Pedro-Pellado). This report, however, implicates Laguna del Maule as the potential location of volcanic unrest.
Quick report tonight brought to my attention by Eruptions reader GuillermoChile. Apparently, the SERNAGEOMIN has been monitoring an earthquake swarm at Chile’s Tatara-San Pedro (also known as San Pedro-Pellado), possibly numbering in the hundreds of small earthquakes over the last few days. The reports are a little scant and the information coming from different parts of the Chilean government are contradictory: the regional governor of the area was quoted as saying that “it is of volcanic earthquakes, so we are on alert” while the regional director from ONEMI said “at first thought that we were facing a volcanic earthquakes, but known reports of the analysis has led to the conclusion that we were facing tectonic type earthquakes“. The article in La Tercera also mentions that the volcano hasn’t erupted in “decades” while the Global Volcanism Program’s entry for San Pedro says that the last eruption is “unknown”, likely in the Holocene (last 10,000 years). So, there seems to be lots of confusion (not to mention La Tercera calling the volcano “Catinao”). If this is renewed activity at the volcano, it is potentially the first in recorded history. Source

JUN 1, MEXICO, POPOCATEPETL VOLCANO
POPOCATEPETL VOLCANO HAS BLASTED A TOWER OF ASH, THREATENS MILLIONS IN MEXICO
Mexico's Popocatepetl Volcano has blasted a tower of ash over nearby towns and villages prompting authorities to consider the possibility of evacuations.
Popocatepetl sits roughly halfway between Mexico City and the city of Puebla, meaning some 25 million people live within a 90-km (60-mile) radius of the volcano.
Over a month ago, the volcanic eruptions started growing larger.

Sirung volcano back to life and on alert level 3
The Sirung stratovolcano on the remote Pantar island in Indonesia has come back to life with a series of probably phreatic explosions and strong degassing.
On May 8, 2012 a 3-hour long eruption took place. The eruption was accompanied by loud sounds and incandescent tephra observed rising 10 m above the crater. The explosion created an ash plume that reached 3.5 km altitude and drifted to the north, producing ashfall up to 4 mm thick near the crater.
During May 9-12 white plumes rose 30-50 m above the crater. A sulfur odor was reported in areas up to 3 km away on 12 May. That same day CVGHM raised the Alert Level to 3 (on a scale of 1-4) and recommended that visitors not approach the volcano within a 2.5 km radius.

MAY 19, MEXICO, POPOCATEPETL VOLCANO
Blasts Continue to Menace People Near Mexican Volcano
Fresh blasts from Mexico’s Popocatepetl volcano spewed fiery rock and caustic ash over residents around the Mexico City suburb of Puebla, already on edge after weeks of ongoing eruption.
Ash soared 2.5 miles into the sky during early Saturday’s explosion, forcing a local airport to close.
Residents of the nearby village of Santiago Xalitzintla rushed into the town square during the middle of the night as terrifying rumblings and blasts caused buildings to shudder.
Last week residents in eastern parts of Mexico City were provided with face masks to protect them against ash raining over the region from Popocatepetl’s blasts.
Prevailing winds have so far spared the capital district from significant ash falls.... SourceLatest webcam image & Live Webcam Links:

La Soufrière (volcano)
http://en.wikipedia.org/wiki/La_Soufrière_(volcano)
La Soufrière (“The Sulfurer”) or Soufrière Saint Vincent is an active volcano on the island of Saint Vincent in the Windward Islands of the Caribbean.

Increased Seismic Activity in Leewards
By the Caribbean Journal staff
There is increased seismic activity around the Leeward Islands, according to the Seismic Research Centre in Trinidad. The Eastern Caribbean is a seismically active area, and the Unit said there was no need to panic — as there are hundred of earthquakes in the seismically active area in and around the region each year.

Increase in Seismic Activity at Montserrat Volcano Forces Zone Closure
By the Caribbean Journal staff
An “noticeable” increase in seismic activity at the Soufirere Hills Volcano has resulted in the closure of the Zone C area near the volcano, which had been reopened for daytime entry in December.
Dr Paul Cole, director of the Montserrat Volcano Observatory, told a radio station Friday that it was a precautionary measure as authorities continue to monitor the volcano.
“Following two volcano-tectonic swarms on the March 22 and 23, 2012 involving 49 and 54 events respectively, mild ash venting began at Soufriere Hills Volcano at around 8:00am local time on March 23,” the MVO said in a statement. “The venting was sourced from the floor of the Feb. 11, 2010 collapse scar, immediately south of the old English’s crater wall and to the west of the long-lived hottest fumarole previously identified.”
The Zone C area, which is comprised of Cork Hill, Weekes, Foxes Bay, Richmond Hill, Delvins and extends 500 metres out to sea is part of the island’s exclusion zone.
It reopened in December 2011, after the hazard level in the area was lowered. The level will likely not be lowered, however, despite the area’s closure.
According to the statement, the ash venting was “clearly pulsatory,” and sent ash 6,000 feet above sea level. It sent black jets of ash rising a few hundred metres above the floor of the collapse scar.
The activity was described as “phreatic,” meaning activity formed when superheated rock meets groundwater, causing the rocks to fragment and generate ash.
“[Volcano-tectonic] earthquakes are related to fracturing rocks probably as a result of increases in pressure,” the statement said. “It is likely that these increases and the resulting earthquakes are related to uprising magma below the volcano.”
Similar types of activity have apparently occurred at the volcano up to several months prior to magma extrusion, both in 2005 and 2008.

Montserrat’s Zone C, Closed Due to Activity at Soufriere Hills, Reo...
By the Caribbean Journal staff
Montserrat’s Zone C on the volcanic risk map has reopened for daytime entry after being closed due to activity at the Soufriere Hills volcano.
The zone reopened last week, according to Governor Adrian Davis.
The area, which comprises Cork Hill, Weekes, Foxes Bay, Richmond Hill, Delvins and extending out 500 metres to sea, is part of the Exclusion Zone.
It was closed in March after a “noticeable” increase in seismic activity. The Zone had reopened for daytime entry in December 2011 after the area’s hazard level was lowered.
Similar seismic activity had occurred at the volcano up to several months prior to reported magma extrusion in 2005 and 2008.
Access is now permitted from 8:00 AM to 4:00PM; boats are permitted to travel through the zone but must not stop.
“The public are asked to note that no entrance is allowed under any circumstances to Zone V on the volcanic risk map,” the Governor said in a release. “Anyone found in this zone is liable to be arrested and charged.”

UK to Conduct Montserrat Seabed Survey
By the Caribbean Journal staff
The United Kingdom’s HMF Protector will be in Montserrat next week to conduct surveys of the island’s seabed.
The role of the ship is to conduct surveys as present charts are out of date — and given changes caused by volcanic activity, there is a need to have more accurate images of the conditions in the waters around the island, according to Richard Aspin, communications officer for the office of Governor Adrian Davis.
The information will both help ships needing to come into the harbour and provide better information for general shipping purposes.
The ship will also be aping the Carrs Bay seabed area to prepare for the proposed construction of its new port.
The HMS Protector is one of the newest additions to the British Navy Fleet — it includes a flight deck and an echo sounder.

St Vincent Volcano “Not More Active”
By the Caribbean Journal staff
St Vincent and the Grenadines’ National Emergency Management Organization received a number of calls Thursday from citizens asking if the country’s La Soufriere volcano was erupting, with some accounts indicating odors of sulphur and smoke billowing from the volcano.
But there is no unusual activity or increase in seismic activity at the volcano, according to the Seismic Research Centre in Trinidad, which informed Howie Prince, Director of NEMO.
NEMO, which said the county continued to be affected by a trough system producing dense clouds and fogs, said rumors that the La Soufriere volcano had become more active were “not true.”
The organization attributed the “illusion of smoke” to lightning flashes combined with low clouds and fog.
La Soufriere, which is also known as Soufriere St Vincent, is the highest peak in the country. Its most recenty violent eruption was in 1979.

Volcanic Activity on Pagan Island - Mariana Islands (May 10) -
http://www.upi.com/Science_News/2012/05/10/Satellite-spots-Pacific-...
Steam and gas plumes from a volcano in the Mariana Islands in the Pacific Ocean.
The image shows the activity on Pagan Island, the largest and one of the most active of the Marianas volcanoes, a NASA release reported Thursday.
Fires and smoke on the island was imaged on Tuesday by the Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Terra satellite.
Pagan Island consists of two volcanoes connected by a narrow isthmus, and almost all of the historical eruptions of Pagan dating back to the 17th century have originated from North Pagan volcano.
The largest eruption of Pagan during historical time took place in 1981 and prompted the evacuation of the sparsely populated island, NASA aid.
The Marianas are an arc-shaped archipelago consisting of the summits of fifteen volcanic mountains, anchored at its south end by the island of Guam.
