                      INFORMATION RELEASE No. 54
                November 23, 1994, 1300 KST (0100 UTC)

An explosive eruption of unknown but probably moderate intensity
occurred beginning about 04:00 (1600 UTC) based on interpretation of
seismic activity.  The volcano was completely obscured by clouds but
as much as 0.5 mm of ash fell in the town of Klyuchi 30 km NNE of the
volcano.  Thirteen strong shallow earthquakes were recorded beneath
the volcano between 04:00 and 12:00.  These earthquakes had a maximum
amplitude of 14.25 microns at a seismic station 14 km from the volcano
and were recorded at stations as much as 70 km away.  Persistent
volcanic tremor with a maximum amplitude of about 0.33 microns was
recorded 14 km from the volcano.  Comparing the seismicity of this
event with that of the observed September 30-October 1 event suggests
that the ash plume may have reached an altitude of about 7 km (23,000
ft above MSL).  The possibility of more steam and ash explosions of
similar character remains high for the near future.
