During September 15-19, gas and ash bursts were rising up to 500-700 m
above the crater.  The eruption column reached a height of 1.5-2.0 km
above the crater (~20,000 ft asl) and extended downwind to the
southeast for more than 50 km.  The lava flows on the northwest and
southwest flanks that are extruding from the two vents 200 m below the
crater rim have now moved down to 2800 m asl.  Phreatic explosions are
occurring at the contact of the northwest lava flow and the glacier.
Lava fountains were observed in the central crater reaching a height
of 300-500 m.

Volcanic tremor is continuous with a maximum amplitude of 6.1 microns
and is recorded at distances of 11 km from the volcano.
