Anatahan Volcano Update
Anatahan Volcano Update for April 15, 2004
Submitted Friday, April 16, 2004 at 0900 local Anatahan time
For the past day or so, the volcanic seismicity at Anatahan volcano has
been high, though somewhat lower than it was during its peak on April
6-7, the highest level since the eruptions of May-June 2003. The
presence of a new, rather flat dome within the crater, and fresh ejecta
around the crater rim, have now been confirmed. Steam and (or) ash
emissions are likely occurring several times per day to altitudes of
less than 3,000 ft (1,000 m), but eruptions to higher altitudes may
occur with little or no warning. Contact persons:
