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

New Zealand Volcano Erupts for First Time Since 1897 ( Aug 6) -
http://www.dailymail.co.uk/news/article-2179847/New-Zealand-volcano...
- Mount Tongariro takes scientists by surprise by suddenly erupting for the first time since 1897
- People evacuated, roads closed and flights cancelled as thick ash spreads over several miles
- Witnesses describe flashes and explosions followed by ash cloud reaching more than four miles high
The 1,968-metre Mount Tongariro erupted late Monday shortly before midnight, throwing rocks into the air that landed up to a half-mile away, but there were no reports of casualties or damage.
Winds carried a cloud of volcanic ash across the centre of the North Island to the east coast city of Napier, more than 201 kilometres away.
Police lifted a warning for people to stay indoors, saying there was no health risk except to people with respiratory illnesses. Civil defence officials cancelled a potential threat advisory.
But the New Zealand Post cancelled deliveries in Napier and nearby Hastings for their carriers’ safety.
The state Institute of Geological and Nuclear Sciences said the eruption, accompanied by a series of small earthquakes, comprised steam from the mountain’s hydrothermal system rather than molten lava ejected from the core.
It said a helicopter flight over the mountain, which last blew in 1897, confirmed that activity had subsided, but it posted a volcanic alert of two on a scale of five and said it could not predict what would happen next.
“As with any volcano, an eruption could occur at Tongariro at any time with little or no warning, and there is an elevated level of risk,” it said.
Scientists admitted they were surprised by the eruption and said heightened seismic activity could continue for several weeks.
Some people left their homes, but there was no official evacuation. Police closed the island’s main highway, linking the capital, Wellington, with the biggest city, Auckland, because of poor visibility during the night, but it was reopened after daylight.
Tongariro is the smallest of three volcanoes in a national park on the central North Island’s plateau. Ski fields on 2,797-metre Mount Ruapehu, an active volcano that last erupted in 2007, continued to operate. Authorities closed Tongariro Alpine Crossing, a popular hiking track, until further notice.
Air New Zealand cancelled flights to and from North Island cities, and off-duty air traffic controllers were called in to help pilots fly clear of the ash cloud.

This image is updated every minute, shows the northern flank of the volcano including the glacier. Intense cloudy or transmission problems, can sometimes prevent the visibility of the volcano

Aug 6, White Island volcano, New Zealand
WHITE ISLAND VOLCANO STATUS CHANGED TO 'ERUPTION', VISITORS WARNED TO STAY CLEAR OF ISLAND
White Island volcano has erupted, prompting GNS Science to advise visitors to take extra care.
The island, located about 50 kilometres off the coast of Whakatane, is an active volcano and a popular tourist spot.
Its web camera captured the small eruption from Crater Lake, GNS Science volcanologist Michael Ronsenberg said.
"These phenomena are not unknown for While Island, but this is the first substantial confirmation that small scale eruptions are now occurring on the island and confirms the risk to visitors has increased," he said.
"Eruptions can occur at any time with little or no warning. We advise extra caution should be taken, if visiting the island."
GNS has changed the volcano's code from "experiencing signs of elevated unrest above known background levels" to "volcanic eruption is underway with no or minor ash emissions".
The alert level has also changed from one to two due to "minor eruptive activity".
It follows a code change last week when scientists discovered water levels in Crater Lake rose by about 3m to 5m overnight and the number of tremors had increased.
There was a particularly stronger seismic episode recorded Sunday morning, ending in a volcanic earthquake at 4.54am that day.
Rosenberg said: "[The earthquake] had a sound signal, which meant something happened on the surface. So we went back and looked at the camera images." ...

Alaska's Cleveland Volcano Has An Explosion, Aug 4
A small explosive event at Cleveland volcano occurred yesterday, August 4, at 8:38 AM ADT (16:38 UTC) based on retrospective analysis of infrasound data. Satellite images show a brief, faint steam plume about 4 hours after the event. Satellite data also detect elevated surface temperatures in several clear views of the volcano last night. AVO has received no reports of activity from mariners or pilots in the vicinity of the volcano.

I folded the Volcanic Explosivity Index (VEI) for each eruption and got the overall rate for each year. The graph shows, that over the past 20 years volcanic activity is growing.
All the data according for Global Volcanism Program:
1991 1992 1993 1994 1995
69 40 43 60 471996 1997 1998 1999 2000

Japan, Sakurajima volcano:600th Eruption this year with Massive Explosion
Volcano blast showers ash on Japanese city
THE Sakurajima volcano in southern Japan has erupted, spewing volcanic ash onto Kagoshima City.
The eruption at one of Japan's most active volcanoes showered ash on the streets of Kagoshima, which lies just 2km across a bay from the volcano.
Residents of Kagoshima donned face masks to protect themselves while sweeping away the ash.
The volcano has erupted more than 600 times this year and is expected to continue its intermittent eruptions.
Currently, the volcano warning there is at level three out of a possible five levels.
A level five would mean that the residents living near the crater would have to be evacuated, while level three warns people not to approach the volcano. Source

JULY 17, INDONESIA, MT.MERAPI
Mount Merapi, located in Yogyakarta, emitted high-pressure gas on Sunday afternoon that caused its crater wall to collapse and volcanic ash to fall on its western slope, as smoke billowed up to 1 kilometer into the sky.
As the gas discharge was not followed by other dangerous volcanic activity, the phenomenon was regarded as a small-scale volcanic eruption and the volcano’s alert status remained normal. ...

* Vigorous Plume from Nyiragongo Volcano [July 5, 2012; Earth Observatory]
Africa’s Mount Nyiragongo—one of the few volcanoes with a permanent lava lake—recently experienced a surge in activity. Since July 3rd, the Toulouse Volcanic Ash Advisory Center (VAAC) reported a series of ash plumes up to an altitude of 18,000 feet (5,500 meters), which is about 6,500 feet (2,000 m) above the volcano’s 11,384-foot (3,470 m) summit. Nyiragongo frequently emits sulfur dioxide, but ash emissions are unusual. This natural-color satellite image shows emissions streaming southwest from Nyiragongo, with an additional plume from nearby Nyamuragira. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite on July 5, 2012.
