Anatahan Volcano Update
Anatahan Volcano Update for April 24, 2004
Submitted Saturday, April 24, 2004 at 1325 local Anatahan time
Anatahan seismic activity increased abruptly at 00:52 4/24 UTC, 10:52
4/24 local time to high levels unseen since summer 2003. These levels
are 3 to 4 times as high as those of the past 6 days. This seismicity
signals a significant increase in Anatahan's eruptive activity from
quiet effusion of a small amount of lava to a more energetic eruption.
The eruptive activity does not appear to be as energetic as the
eruptions of May and June 2003. Vigorous activity at this level is
continuing at the time of this report. The next seismic update will be
at 07:00 4/24 UTC,17:00 4/24 local CNMI time. Contact persons:
