Mount St. Helens continues to rest after its eruption was declared over in January, according to today's weekly update from the Cascade Volcanoes Observatory in Vancouver.
Here is the text of the update:
Activity Update: All volcanoes in the Cascade Range are at normal levels of background seismicity. These include Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams in Washington State; Mount Hood, Mount Jefferson, Three Sisters, Newberry Volcano, and Crater Lake, in Oregon; and Medicine Lake, Mount Shasta, and Lassen Peak in northern California.
Mount St. Helens has been at Volcano Alert Level NORMAL (Color Code GREEN) since July 10, 2008, a change assigned 5-6 months after the late January cessation of its 2004-2008 eruption.
Fieldwork at Mount St. Helens comprised a test installation of a self-healing, self-forming mesh network for monitoring instruments. The goal is to have a robust network of instruments that are interconnected for their radio communications, so that the loss of one or even a few installations does not compromise the ability to transmit data.
At the Three Sisters, GPS and seismic stations were winterized.
At Crater Lake, four broadband receivers were recovered, following their summer 2008 deployment for a seismic-monitoring experiment.
The U.S. Geological Survey and University of Washington continue to monitor these volcanoes closely and will issue additional updates and changes in alert level as warranted.

A volcanic eruption on the Kamchatka Peninsula sent clouds of smoke and ash into the air above Russia's Far East on Thursday, a scientist said, warning of dangers to local inhabitants and passing airplanes. The 4,750 m Klyuchevskoy volcano is spewing out rocks, ash and gases, said Alexei Ozerov, a scientist with the Institute of Volcanology and Seismology of the Far Eastern branch of the Russian Academy of Sciences. "The luminescence in the volcano's crater is becoming more intensive, which testifies to the appearance of new lava," Ozerov said, adding that the eruption would probably last from two or three weeks to six months. Continuous flows of lava running down Klyuchevskoy's slopes could trigger mudslides as the molten rock melts the snow and ice, endangering people living in nearby villages, the scientist said. The volcano eruption is also a threat to aircraft flying overhead as volcanic ash could cause planes considerable damage, he added. The last powerful eruption of the Klyuchevskoy volcano took place in 2005.) |

JAKARTA (Reuters) - Indonesia has raised the alert level for a volcano on Sulawesi island after it began spewing hot clouds and lava, a vulcanology official said on Tuesday.
Lava from Soputan volcano flowed up to 1 km (over half a mile) from the crater while white clouds and fiery sparks shot up about 150 meters from the peak, said Surono, the head of the vulcanology center.
The official said the status was raised to the second highest level on Monday and campers had been told to stay away from the volcano, but people living on the slopes are not being evacuated as the lava will not reach that far.
Indonesia has the highest number of active volcanoes of any country, sitting on a belt of intense volcanic and seismic activity known as the "Pacific Ring of Fire."
People often live and farm on the slopes of volcanoes because of the rich volcanic soil.
In the past two years, at least three major volcanoes, including Anak Krakatau, have showed signs of increased activity, but there has been no serious eruption.
