Akutan Volcano, Aleutian Islands, Alaska

Update 012

Alaska Volcano Observatory Update
Monday, March 25, 1996 4:00 pm AST (0100 UTC)

Level Of Concern Color Code: YELLOW

The number of earthquakes recorded in the vicinity of Akutan volcano continues at a rate of about 60-80 per day. Although the threat of an imminent eruption has decreased, the volcano remains restless. Data from five seismic stations near Akutan are transmitted in real-time to AVO, which is staffed around the clock to provide analysis and interpretation of seismicity.

The following scenarios are considered possible:

  1. Earthquake activity continues to decrease, with some fluctuations, and no eruption occurs.
  2. Earthquake activity intensifies leading to an eruption of a lava flow from the flank or within the summit caldera, accompanied by ash plumes and explosions.
  3. Earthquake activity intensifies leading to an explosive eruption accompanied by ash plumes.

The next update will be issued on wednesday unless the level of seismicity changes significantly

AVO is closely monitoring the situation. Recordings of current information are available by calling 907-786-7478. Information on the Akutan situation is also available on the Internet: http://www.avo.alaska.edu/
