Anatahan Volcano Update
Anatahan Volcano Update for April 19, 2004
Submitted Tuesday, April 20, 2004 at 1037 local Anatahan time
Seismicity during the past day was relatively high but steady, unchanged
from the day before. The seismicity suggests continuing quiet, effusive
eruption of a relatively small volume of new lava 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). Eruptions to higher altitudes
could, however, occur with little or no warning.
