Anatahan Volcano Update
Anatahan Volcano Update for April 16, 2004
Submitted Saturday, April 17, 2004 at 0900 local Anatahan time
For the past day or so, the volcanic seismicity at Anatahan has been
high, though somewhat lower than 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 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:
