Anatahan Volcano Update

Anatahan Volcano Update for April 7, 2004
Submitted Thursday, April 8, 2004 at 1100 local Anatahan time


For the past day Anatahan volcanic seismicity has again been a fairly high level, though slightly less intense than it was yesterday, the most intense day since the eruption of May-June 2003. We believe the style of seismicity indicates steam and (or) ash emissions are occurring to low altitudes of less than 3,000 ft (1,000 m).
