Anatahan Volcano Update for April 26, 2004
Submitted Monday, April 26, 2004 at 0500 local Anatahan time

Anatahan seismic activity increased abruptly at 0052 4/24 UTC (1052 4/24 CNMI) to a high level unseen since summer 2003, marking a significant increase in Anatahan's eruptive activity from quiet effusion of small amounts of lava to a more energetic eruption. The eruptive activity now appears to be as energetic as some of the eruptions of mid-June 2003. Seismic activity  continues to increase slowly at the time of this report.

The next update will be at 0000 4/26 UTC (1000 4/26 CNMI).
