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

Italy, Etna volcano - 14th paroxysm of SE crater in progress
Osservatorio Etneo reported that the fourteenth eruption from Etna's New SE Crater in 2011 occurred during poor weather conditions on 19 September. Lava fountains rose from multiple vents within the crater and lava flows descended the W slope of the Valle del Bove. An ash plume drifted NE; ash and lapilli fell in an area to the N of Giarre (16 km E). The main phase of the event lasted from about 1020 until just after 1300. During the evening the lava flows were active and weak spattering continued from a vent at the SE base of the SE Crater cone....

Usa, Cleveland volcano - Volcano on Alaska's remote Aleutians oozes lava
A volcano in Alaska's remote Aleutian Islands has begun oozing lava, a signal that the mountain could explode and send up an ash cloud that could threaten aircraft. Satellite images show lava is building in the crater at the summit of 5,675-foot Cleveland Mountain on an uninhabited island about 940 miles southwest of Anchorage, according to the Alaska Volcano Observatory. "It's forming a dome-shaped accumulation in the crater," said Chris Waythomas of the U.S. Geological Survey, the observatory's acting scientist in charge. "We call these things 'lava domes.' It looks like a muffin top." Lava domes form a lid on a volcano's "plumbing," including the chamber holding the magma. When they grow big enough, lava domes become unstable and will sometimes collapse, decompressing the magma chamber and leading to an explosion, Waythomas said. "They can seal up the conduit and prevent gasses from escaping and lead to an explosive event," he said. Such an explosion from of the volcano on Chuginadak Island could send an ash cloud 20,000 feet or more into the air, the observatory said. The nearest village, Nikolski, is on another island about 50 miles east and has 18 permanent residents. In previous eruptions of Cleveland Volcano, the village was not considered to be in harm's way.
"The plume would have to head directly to Nikolski to cause any problems," such as ash that could cause respiratory problems or damage engines, Waythomas said. If the village uses surface water for drinking, ash could temporarily foul it. The larger threat from ash clouds is to aircraft. Alaska's Redoubt Volcano blew on Dec. 15, 1989, and sent ash 150 miles away into the path of a KLM jet carrying 231 passengers. Its four engines flamed out. The jet dropped more than 2 miles, from 27,900 feet to 13,300 feet, before the crew was able to restart all engines and land the plane safely at Anchorage. The Federal Aviation Administration and the airline industry get concerned for trans-Pacific flights when an ash cloud has the potential to exceed the 20,000-foot threshold, as Cleveland Volcano has done in the past. "Generally anything above that altitude can be hazardous to overflying aircraft," he said. Cleveland Volcano's last major eruption was in 2001. It has had bursts of activity nearly every year since then, Waythomas said. The lava dome now measures 540 feet in diameter, up from 490 feet Sept. 9. Waythomas said a satellite image indicated the lava dome was about 65 feet below the low point on the crater rim.
"The crater is starting to fill up," he said. "This could take another week or two and it will be there. And then we're not sure what will happen." The lava flow may stop, or lava could spill over and descend the mountain's flank. "It may not do anything explosive. It may just ooze over," Waythomas said. "Or it could cause the dome itself to collapse just because it becomes unstable at that point. It's on a steep slope and there's nothing holding it up there." The observatory, a joint program between the U.S. Geological Survey, the University of Alaska Geophysical Institute and the state Division of Geological and Geophysical Surveys, was formed in response to the 1986 eruption of Mount Augustine. In announcements about Cleveland Volcano, the observatory warns that it does not have a real-time seismic network on the remote volcano and cannot track its earthquake activity, forecast imminent eruptions or even confirm explosive, ash-producing events.

Indonesia, Mt. Marapi - W.Sumatra volcano continues to expel smoke, dust
Mount Marapi in Tanah Datar, West Sumatra, has been spewing black smoke and volcanic dust since Wednesday morning.
Residents living near the mountain said the smoke coming out of the volcano on Wednesday was much thicker than usual.
"When the mountain spew thick black smoke, it is usually not followed by volcanic ash. The dust can be seen on clothes being dried and on leaves," resident Sinaro said Wednesday as reported by kompas.com.
A Mt. Marapi observer at the Vulcanology and Geological Mitigation Center, Warseno, said the mountain had been spewing volcanic dust mixed with sulphur from its peak.
As of Tuesday, the volcanic dust had reached heights of up to 200 meters into the atmosphere as of Tuesday and had spread across several districts and municipalities in West Sumatra.

Russia, Karymsky (Kamchatka) volcano spews ash again
The Karymsky volcano on Russia’s Kamchatka Peninsula is spewing ash 6 kilometers high into the sky, seismologists said on Monday.
The eruption has already received the orange volcanic alert status warning aircraft about the presence of ash particles in the air.
The 1,536-meter Karymsky is the most active volcano of Kamchatka’s eastern volcanic zone.

Indonesia, Mt.Tambora - History’s deadliest volcano comes back to life in Indonesia, sparking panic among villagers
Bold farmers in Indonesia routinely ignore orders to evacuate the slopes of live volcanoes. But those living on Tambora have taken no chances since history’s deadliest mountain rumbled ominously to life this month.
Authorities raised a volcano alert at Tambora about two weeks ago, but even when they announced the all-clear, many villagers have refused to return home until days later.
Many of the villagers have been told since their childhood about how the mountain they call home once blew apart in the largest eruption ever recorded — an event that has been widely forgotten outside their region.
The 1815 blast killed 90,000 people, blackened the skies around the globe and was 10 times stronger than the Krakatoa eruption of 1883.

Usa, Cleveland volcano - Continued growth of the lava dome
A thermal anomaly was observed in satellite data over the past day, which is consistent with continued growth of the lava dome. No ash emissions have been observed during this current eruptive episode that began in mid-July 2011. No other new reports have been received regarding the volcano.....

Usa, Long valley caldera - Twenty-seven earthquakes in the past week
Twenty-seven earthquakes between magnitude 1.0 and 2.8 occurred in the Mammoth Lakes-Long Valley region in the past week. All the events, with the exception of one earthquake in the caldera and two in Round Valley, were located in the Sierra Nevada.
