Anatahan Volcano Update
Anatahan Volcano Update for April 13, 2004
Submitted Wednesday, April 14, 2004 at 1000 local Anatahan time
For the past day or so, Anatahan volcanic seismicity has been quite
high, though not quite as high as 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 has now been confirmed. Fresh
ejecta
has been observed near the crater rim. Steam and (or) ash emissions are
likely occurring several times per day to altitudes of less than 3,000
ft (1,000 m), but emissions or eruptions to higher altitudes could occur
without much warning. Contact persons:
