Scientists say seismic activity suggests Alaska volcano getting ready to erupt again

October 8th, 2009 WASHINGTON - A new study has revealed that some of the world's most dangerous volcanoes can erupt much more quickly than scientists had suspected. According to a report in National Geographic News, the study took into account the massive 2008 eruption of Chile's Chaiten volcano.

October 5th, 2009 Montserrat volcano shoots plume of ash into skySAN JUAN, Puerto Rico — The volcano on the Caribbean island of Montserrat shot a plume of ash more than two miles (three kilometers) into the sky Monday, lightly dusting the small Caribbean island. The venting by the Soufriere Hills volcano has been accompanied by more than 30 tiny earthquakes since Sunday night, according to Paul Cole, director of the Montserrat Volcano Observatory.

September 6th, 2009 Nicaragua's San Cristobal volcano spews ashes, gasMANAGUA, Nicaragua — Nicaragua's San Cristobal volcano has let off a series of explosions, spewing gases and showering ash on nearby towns. There are no reports of injuries or damage.

September 3rd, 2009 WASHINGTON - Scientists have developed a new technique that uses data collected from earthquakes, potentially allowing the Earth's seismic activity to be mapped more comprehensively. Scientists from the University of Edinburgh, Scotland, developed the new method.

August 15th, 2009 WASHINGTON - NASA scientists have placed about a dozen monitoring 'spiderbots' inside the volcanic crater in Mount St Helens in the US, which are high-tech devices that can detect an impending eruption. Mount St. Helens is one of the most active volcanoes in the US.

August 11th, 2009 LONDON - NASA scientists have developed a network of volcano sensors known as 'spiderbots' that can automatically communicate with each other, and placed them inside Mount St Helens in the US. Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States.

July 14th, 2009 Alaska terminal near volcano to resume moving oilANCHORAGE, Alaska — An oil pipeline company plans to resume shipments from its terminal near the base of an Alaskan volcano that has sent hot boulders, huge ice chunks and mud flowing toward the terminal on several occasions since becoming active again in March. Delaware-based Cook Inlet Pipeline Co.

July 10th, 2009 Philippines' most active volcano restive againMANILA, Philippines — Scientists say the Philippines' most active volcano is rumbling again while emitting steam and a strong glow at the summit crater that can be seen with the naked eye. State volcanologists say the frequency of volcanic earthquakes has increased on Mayon signifying the possible movement of magma below the surface that could lead to ash explosions and eventually eruption.

July 4th, 2009 WASHINGTON - A new study has determined that glaciers are the reason behind seismic activity and earthquakes in Iceland. The study was carried out by Kristin Jonsdottir, Roland Roberts, Veijo Pohjola, Bjorn Lund, Zaher Hossein Shomali, Ari Tryggvason, and Reynir Boovarsson from the Department of Earth Science, Uppsala University, Uppsala, Sweden.

July 2nd, 2009 Hawaii volcano glow snuffed out by falling rocksVOLCANO, Hawaii — The bright glow at the summit of Hawaii's Kilauea (KILL'-uh-WAY'-uh) volcano has been snuffed out by a series of large rock falls within its crater. The Hawaiian Volcano Observatory says the rock falls on Tuesday produced a seismic signal equivalent to a magnitude-2.4 earthquake.

June 30th, 2009 Scientists lower Alaska volcano threat levelANCHORAGE, Alaska — Alaskans can put away their dust masks and spare air filters, for now, because Mount Redoubt seems to have cooled off since its last major eruption nearly three months ago. The Alaska Volcano Observatory said Tuesday that seismic activity has slowed under the volcano and it's possible that eruptions have stopped.

June 9th, 2009 BOGOTA - Thousands of people have been evacuated after a volcano erupted in southwestern Colombia. The Galeras Volcano erupted twice in the past two days.

June 7th, 2009 Scientists eye glowing volcano crater in HawaiiVOLCANO, Hawaii — The summit of Hawaii's Kilauea volcano is glowing brightly as molten lava swirls 300 feet below its crater's floor, bubbling near the surface after years of spewing from the volcano's side. The expanding vent of Halemaumau crater helps confirm scientists' belief that the lava is close to the surface of the summit, said Janet Babb, a geologist and spokeswoman for the U.S.

May 4th, 2009 Alaska volcano shows increased unrestANCHORAGE, Alaska — Mount Redoubt showed increased unrest Sunday as the volcano continued to rumble and grumble and produced a substantial ash and steam plume. On Sunday, scientists said there was a marked increase of seismicity at the volcano about 100 miles southwest of Anchorage.

April 24th, 2009 Indonesian volcano spews lava and ash into the skyJAKARTA, Indonesia — Officials say a volcano in central Indonesia is spewing ash and lava hundreds of meters (yards) into the air. But villagers living near Mount Slamet do not appear to be in immediate danger.
