Anatahan Volcano Update
Anatahan Volcano Update for April 24, 2004
Submitted Saturday, April 24, 2004 at 1700 local Anatahan time
Anatahan's seismic activity increased abruptly at 00:52 4/24 UTC, 10:52
4/24 CNMI, to high levels unseen since summer 2003, marking 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 now appears to be as energetic as the eruptions of mid-June
2003. Seismic activity is continuing or slowly increasing at the time of
this report. A second-hand pilot report estimates plume height at
3000-3500 feet, extending west-northwest from Anatahan. The next seismic
update will be at 11:00 4/24 UTC, 21:00 4/24 CNMI.
