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

Hawaii, Kilauea volcano - Lava flow resumes to southeast and northeast
The Hawaiian Volcano Observatory has released new pictures of the eruption on Puu Oo crater.
An overflight of the flow on Friday showed lava advancing about 1.6 miles to the southeast from the fissure and .3 miles to the northeast from another flow, scientists said.
The observatory also released a thermal image of the lava flow showing active flows near the fissure spreading out. The image shows a pahoehoe flow (smooth, swirling lava) moving southeast and the small flow to the northeast. An aa (rough, broken lava) field is seen below the active flows.
The volcano is going through a series of what scientists call deflation/inflation events as the volcano apparently fills with magma, which is then released. The deflation/inflation often coincides with lava pulses and pauses in the eruption.
Within Puu Oo crater, scientists said lava has filled a pond on the east side of the crater and a glow could be seen on the west.

El Hierro update - Eruption is growing in size
Ramon Ortiz, a vulcanologist specialized in Canary Island volcanoes and currently advising the authorities, says in ElMundo that today’s eruption will be probably at a depth greater than 600 meter below sea level and about 5 km to the southeast of El Hierro.
Ortiz also said that the the Harmonic Tremors which started this morning showed that the eruption had started......From what I can tell, based on the harmonic tremor plots. It seems that the eruption has been growing in size since it started well over 12 hours ago. This suggests that the eruption is growing in size. That also brings up the issue that new fissures might open, both into deeper ocean and on shallower depth and even on land without any warning at all...

Indonesia, Six volcanoes on high alert, but no evacuations for now
Despite increasing activity at six volcanoes across the country, the National Disaster Management Agency (BNPB) says there is no need to evacuate residents for now.
BNPB spokesperson Sutopo Purwo Nugroho said on Sunday that the volcanoes on high alert were Mount Tambora in West Nusa Tenggara, Anak Ranakan in East Nusa Tenggara, Papandayan in West Java, Karangetang and Lokon in North Sulawesi, and Anak Krakatau in the Sunda Strait.
“These volcanoes are on alert level III, which means all volcanic parameters show that activities could develop into an eruption or disaster,” he told The Jakarta Post via text message.
He said that Anak Krakatau was producing five thousand tremors per day. A 2-kilometer exclusion zone has been set up around the volcano.
Sutopo said the volcanoes were being monitored 24 hours a day.

Canary islands, El Hierro volcano - Nearly 9,000 seismic movements on the island since July 17 + rising ball of lava
Intense swarms of tremors beneath one of the volcanic Canary Islands has placed residents of El Hierro on alert for a possible eruption.
Spain’s Instituto Geografico Nacional (IGN) reported the nearly 9,000 seismic movements on the island since July 17 have caused measurable changes in the terrain.
El Hierro’s only eruption during recorded history was in 1793, when the Volcano de Lomo Negro vent rumbled for a month and produced lava flows.
Seismologists say they don’t know if the rising ball of lava causing the latest rumblings will break through the surface, but they have issued a “yellow” alert as a precaution.
IGN Director Maria Jose Blanco told reporters that any eruption would most likely have a “low explosive value.”
Tremors about 50,000 years ago produced an enormous landslide that cascaded into the ocean, creating a large tsunami that probably reached the North American coast.

Indonesia, Warning status for Anak Krakatau
The drastic increase in volcanic earthquake activities at Anak Krakatau has forced authorities to warn of a possible eruption.
All quarters have been asked not to approach within a two-kilometre radius of the volcano, located in the Sunda Strait. Normal activities are still allowed outside the radius.
Anak Krakatau is 40km from the coast of Lampong, Sumatera, and the coast of Anyer-Carita coast, Jawa.
Local media quoted Head of Volcanology and Geology Disaster Mitigation Centre, Surono, yesterday that the seismograph recorded between 6,000 and 7,000 volcanic earthquakes a day.
Prior to this, the seismograph only recorded between 100 and 300 volcanic events a day, said Surono to Indopos, as quoted by news portal Jawa Post National Network.
Antara news agency quoted Andi Arief, Special Presidential Staff Disaster Areas Social Disaster Assistant, that, in theory, anything more than 1,000 earthquake activities could cause Anak Krakatau to erupt.
He said the type of eruption has yet to be ascertained because developments are still at the intensive monitoring level.
Since Anak Krakatau appeared on the surface of the sea on June 11, 1927, the volcano has erupted more than 100 times, with a dormant period of between one to six years.
The explosive eruption of Anak Krakatau last July 10 hurled hot ash into the sky to a radius of 700 to 1,000 metres from the centre of the eruption, causing damage to seismic equipment placed at the volcano.
The explosive eruptions which took place in the last four years were the magmatic type, throwing volcanic material and dust for 1,000 to 1,500 metres around Anak Krakatau.
How wide the volcanic dust was spread, however, depended on the strength and direction of the wind.

Iceland, Intense swarm of earthquakes in Katla volcano
Measuring devices this morning have picked up a large earthquake swarm, usually a tell-tale sign of a potential volcanic eruption.
In the early hours of today, 05 October 2011, an intense swarm of earthquakes was registered in the Katla caldera; the largest of these earthquake had a local magnitude of ~3.7. Most of the ongoing seismicity is sourced at shallow (< 5 km) depths.Evidence gathered by geophysicists showed the magma had risen to the height of the glacier ice above the volcano causing it to melt.
They said the high seismic tremors recorded on July 8 and 9 confirmed Katla had become active and started small eruptions.
Today's intense swarm of earthquakes started at midnight and dozens of tremors have been recorded - the strongest with a magnitude of 4 at around 3am.http://www.clickgreen.org.uk/news/international-news/122604-earthqu...

Alaskas Cleveland Volcano Closer to Erupting
If the lava dome continues to grow in the summit crater, the possibility of an explosive event increases. With continued lava dome growth, lava may eventually overflow the crater rim to produce a lava flow and/or collapse to produce pyroclastic flows. Sudden collapse of the effusing lava could result in the generation of a volcanic ash cloud....

New Zealand, alert level at Ruapehu remains at 1, despite the temperature of the crater lake rising towards conditions typical for an eruption.
GNS Science says the volcanic alert level at Ruapehu remains at 1, despite the temperature of the crater lake rising towards conditions typical for an eruption. Skiers on the Whakapapa ski field in the central North Island have reported smelling hydrogen sulphide gas in recent weeks. Volcanologist Brad Scott says this is because the temperature of the crater lake is cooler, which tends to produce more gas. The latest Volcanic Alert Bulletin says the lake's temperature on 29 September was 17.6 degrees Celsius. In March, the temperature peaked at 41 degrees Celsius. Mr Scott says the lake is heading towards a temperature where volcanic activity typically occurs, but doesn't always. Ruapehu is an active volcano and future eruptions may occur with little or no warning. The eruption detection system on the mountain functioned well during a test last week, he says.
