MOUNT ST. HELENS, WASH. – Mount St. Helens in Washington state has erupted, sending a plume of steam and ash 7,600 metres into the air. The volcano has been active in previous months. A minor eruption lasted 24 minutes last October, sending up 3,000 metres of steam and ash. The U.S. Geological Survey detected magma moving below the surface, along with the increased presence of gases such as carbon dioxide, indicating a violent explosion, but nothing happened. It grew a dome top 80 stories high in December, which began expanding at a rate never seen before by scientists studying the volcano. Infrared images showed fresh lava was rising at temperatures of almost 800 C. At the time, scientists said it would take 11 years before erupting the way it did back 1980, when it killed 57 people and covered towns more than 400 kilometres away with ash.

But the eruption of the volcano, which exploded into life in 1980, killing 57 people, did not appear to pose an immediate danger to people as the area is sparsely inhabited, they said. "There was an eruption at 5:30 pm local time (0130 GMT) and the cloud of ash is estimated at 36,000 feet," Rob Harper told Agence France-Presse. "We are monitoring the situation." KOMO television in the Oregon city of Portland showed the giant plume hanging over the crater of the volcano which rumbled back to life last October after years of silence. The huge plume of smoke and ash prompted the Federal Aviation Administration to order air traffic to avoid the area.

ping! Those Oregon earthquake swarms and that 5.2 yesterday...
Damn it, I'd love to see Bernard Chouet's outbound email about now. If that guy says it's time to haul ass, you better have your keys in your hand already.
LOL! Thanks for a new name. He certainly is into volcanoes: Bernard Chouet interviewed by NOVA And the BBC in 2003:
Yikes! I'm not so flippant about the "mere 5.2" now!!!
Well.......damn! Hope it doesn't do anything like it did back in 80. That ash fallout was a bitch to deal with. Ash can get into places beach sand can only dream of! Shee-it!
Damn! I didn't learn about it until after dark; I live in Seattle.
The guy is my God. Ever since the Nova special, I've followed his work. It is the quintessence of science to look at the same pile of data everyone else has looked at and extract the correct answer. After Stanley Williams gas emission theory for predicting eruptions got about 10 of the world's other pre-eminent volcanologists parboiled or reduced to reddish pink pulp by rocks the size of a hall closet in Galeras, people started listening more closely to Chouet, whose eulogies at their funerals SHOULD have consisted mostly of "I told you so..."
Scientists seek source of Mount St. Helens blast VANCOUVER, Washington (CNN) -- Scientists want to peer inside the crater of Mount St. Helens on Wednesday to locate the origins of a plume of ash and steam that spewed nearly seven miles high into the air Tuesday night. Geologists cautioned the explosion wasn't necessarily a harbinger of a larger or more destructive eruption. The U.S. Geological Survey in Vancouver began a 24-hour volcano watch after the eruption at 5:20 p.m. (8:20 p.m. ET). Nearly five hours later, the plume remained visible in satellite photos. Glowing tendrils of lava were spotted inside the mountain's crater following the explosion. Although the plume rose nearly twice as high as one produced by the last eruption in October, the geological agency classified the event as "small," according to an advisory on the Web site of its Cascades Volcano Observatory. No damage or injuries were reported. Some air traffic had to be routed around the plume as it rose to 36,000 feet. The ash remained in the air over Montana on Wednesday and was visible for more than 50 miles (80 kilometers), prompting some motorists to stop their cars and watch. Scientists waited for daylight Wednesday to use a surveillance helicopter to fly over the mountain's crater and determine the plume's origins. Although the geological agency has instruments in place to measure volcanic activity, five of the seven monitoring stations in the crater stopped transmitting after the blast. They were likely damaged. Mount St. Helens, about 45 miles (72 kilometers) east of Vancouver, has been rumbling and spewing steam since September. Scientists said Tuesday's event was to be expected, given the volcano's eruption cycle. Geologists said activity points to an explosive eruption, though none said they believe it will reach the intensity of the 1980 blast that killed 57 people and knocked more than 1,000 feet off the top of the mountain. The 1980 eruption created the mountain's current crater. A new lava dome has been forming inside that crater for several months, and the geological agency reported Tuesday that the growth will be accompanied by low-level tremors and emissions of steam, volcanic gases and ash. "This is clearly part of the ongoing activity which we said can occur and can occur without warning," said a Dan Dzurisin, a spokesman for the geological agency. Penelope Cassidy, a spokeswoman for the Washington State Emergency Operations Center at Camp Murray, said only essential staff was on duty there. The center is outside Tacoma, more than 80 miles (129 kilometers) north of Mount St. Helens. "We're monitoring the situation as we have since late September," Cassidy said. "It's just part of the ongoing shifting of the mountain." CNN's Katherine Barrett contributed to this report.
