Anatahan Volcano Update
Anatahan Volcano Update for April 20, 2004
Submitted Wednesday, April 21, 2004 at 0928 local Anatahan time
Seismicity during the past day was relatively high but steady, unchanged
from the 2 days before. The seismicity suggests continuing quiet,
effusive eruption of a relatively small volume of new material onto the
crater floor. Any steam and ash emissions associated with today's
activity are not likely to exceed 3,000 ft (1,000 m) in height.
Eruptions to higher altitudes, however, could occur with little or no
warning.
