Two volcanoes in Eastern Russia , Kamchatka and one other in Indonesia, have erupted around the same time as the Japan 8.9-magnitude Earthquake on Friday.

Meteorologist Kevin Martin is the lead scientist here at TheWeatherSpace.com and explains in his own way what may actually be happening.

"Waves from the Earthquake have been ringing the planet like bell, causing stress in all sections of the planet", Martin said. "Imagine a calm magma chamber that just needs one push, even if a few feet. This would be enough to cause instability in the chambers, causing volcanic eruptions in various locations. These three eruptions will not be the only mountains to go and other quakes worldwide will follow as the worldwide faults get disturbed.

Mount Karangetang spews out smoke during its last eruption in July 2006.
Manado - One of Indonesia's most active volcanos has erupted, sending lava and searing gas clouds tumbling down its slopes.

Volcanology official Agus Budianto said Friday that authorities were still trying to evacuate residents living along the slopes of Mount Karangetang.

There were no immediate reports of injuries or serious damage.

The 5,853-foot (1,784-meter) mountain is located on Siau, part of the Sulawesi island chain. It last erupted in August, killing four people.

Indonesia, the world's largest archipelago, is located on the so-called Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin.

The eruption happened hours after a massive earthquake in Japan that triggered a Pacific-wide tsunami.

Lava flows on the Pu'u O'o crater on Kilauea Volcano on Sunday, March 6, 2011 in Hawaii. Scientists say the Pu'u O'o crater floor has collapsed and an eruption occurred along the middle of Kilauea Volcano's east rift zone. Scientists at the Hawaiian Volcano Observatory say after a fissure broke out around 5 p.m. Saturday, lava was seen erupting up to 65 feet high.
A new vent has opened at one of the world's most active volcanoes, sending lava shooting up to 65 feet high, scientists at Kilauea volcano said Sunday.

The Hawaiian Volcano Observatory said the fissure eruption was spotted shortly after the floor at the Pu'u O'o crater collapsed around 5 p.m. Saturday. It occurred along the middle of Kilauea's east rift zone, about 2 miles west of Pu'u O'o.

"As a volcanogist, this is what we do. These are the moments we wait for," volcanogist Janet Babb told KHON2. "It is exciting to see an eruption begin particularly if you can see it from the very start."

Iceland: Earthquake Activity Increases Again in Krýsuvík Volcano

It appears that Krýsuvík volcano earthquake activity is increasing again. This time around it appears that the earthquake activity in Krýsuvík volcano has moved more to the west then last weeks earthquake activity.

The biggest earthquake so far is a ML2.1 earthquake with the depth of 6.9 according to automatic data on Icelandic Met Office web page.

The geologists with the USGS Hawaiian Volcano Observatory have released a first look at the new fissure eruption that just started today between Pu'u 'O'o and Napau Crater.

According to geologists, the first portion of the video was shot from the air looking southwest at the fissure eruption between Pu'u 'O'o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can't be picked out at this distance.

The second part of the video was shot from the ground in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.

Hawaii Volcano Sudden Change: Pu'u O'o Collapse, New Eruption Site

Pu‘u ‘O‘o
At 1:42 p.m. HST this afternoon, USGS Hawaiian Volcano Observatory (HVO) monitoring network detected the onset of rapid deflation at Pu'u 'O'o and increased tremor along Kilauea Volcano's middle east rift zone. At 2:00 p.m., Kilauea's summit also began to deflate.

Between 2:16 and 2:21 p.m., the floor of the Pu'u 'O'o crater began to collapse, and within 10 minutes, incandescent ring fractures opened on the crater floor a few tens of meters away from the crater wall. As the floor continued to drop, lava appeared in the center of the crater floor, the northeast spatter cone within Pu'u 'O'o collapsed, and an obvious scarp developed on the west side of the crater floor, with lava cascading over the scarp toward the center of the crater.

At 2:41 p.m., the scarp on the west side of the crater floor appeared to disintegrate, exposing incandescent rubble. Five minutes later, the collapse of a large block along the east crater wall produced a dust plume.

Webcam images showed that the Pu'u 'O'o crater floor continued to drop through 4:26 p.m., when fume obscured the camera view. HVO Webcam images can be accessed here.

Mount Bulusan volcano spews ash in Sorsogon province, eastern Philippines, Nov 2010.
One volcanic earthquake and at least three rockfall incidents were recorded near restive Bulusan Volcano in Sorsogon in the last 24 hours, the Philippine Institute of Volcanology and Seismology said Friday.

In its 8 a.m. update, Phivolcs also noted weak steaming activity at the southeast thermal vent.

"Bulusan Volcano's status remains at Alert Level 1. This means that the source of activity is hydrothermal and shallow. Entry to the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited, since the area is at risk to sudden steam and ash explosions," it said.

Citing the prevailing wind direction, Phivolcs reminded residents in the northwest and southwest sectors of the volcano to take precautions against ash falls.

It also said civil aviation authorities must warn pilots to avoid flying close to the volcano's summit as ejected ash and volcanic fragments from sudden explosions may be hazardous to aircraft.

Mud volcano in Indonesia to erupt until 2037

Image
A mud volcano in Indonesia is expected to continue erupting over the next 26 years according to international reports.

"Lusi," a mud volcano in Sidoarjo of East Java, Indonesia, first erupted on May 29, 2006. The 40 Olympic-sized pools of mud the volcano spewed a day during its peak buried homes and land in a 7-square kilometer radius, displacing over 13,000 families.

Based on the flow of mud, which has now slowed to 4 pools a day, researchers estimate that Lusi will continue to erupt until 2037.

"Our estimate is that it will take 26 years for the eruption to drop to a manageable level and for Lusi to turn into a slow bubbling volcano," Richard Davies, professor of Earth sciences at Durham University in England, said.

Philippines: 13 lahar-related 'quakes' rock Mount Bulusan area

Image
At least 13 volcanic quakes were recorded around restive Bulusan Volcano in Sorsogon in the last 24 hours, state volcanologists said Monday morning.

The Philippine Institute of Volcanology and Seismology said the quakes were "lahar-related" - a day after lahar flows affected water supply in parts of Sorsogon.

"Bulusan Volcano's seismic network recorded 13 lahar-related seismic signals during the past 24 hours. Steaming activity was not observed due to thick clouds covering the active vents and summit crater. Continuous heavy rain over Bulusan Volcano yesterday saturated loosely deposited ash and rock fragments and generated small lahar flows to roll down the slopes of the volcano then flowed along river channels," Phivolcs said on its website.

It said channel-confined lahar flows were observed along Cogon and Monbon river channels.

Other than that, it said no other significant volcanic activity was observed since the last ash explosion on Feb. 21.

Pakistan: New island forms off Balochistan coast


Hingol, Balochistan - A soft muddy island appeared a few kilometers offshore in Hingol on the Makran coast, Balochistan on November 16, 2010. The Director General, Geological Survey of Pakistan (GSP) dispatched a team of earth scientists to investigate the sudden appearance of this white mud dome, about three kilometres offshore near the Kund Malir beach.

The island is 90 metres high with a span of approximately three kilometers.

Before the upsurge of sludge, local fishermen reported high tides near the coast and several boats were trapped due to the emergence of this mud volcano from nowhere. Another island of similar nature was also reported to have appeared 12 years ago. That island disappeared into the sea after four months. It is inferred that this mud dome which is given the name of Khizr, will also disappear with passage of time when methane and other gases are released from this structure.

The pictures taken by GSP earth scientists during their field investigations shows the eruption of white hot muddy sludge on top of the island. The ejected material is a sludge of fine solids, hydrate-bearing sediments suspended in acidic water and hydrocarbon fluids.
