The summit eruption continues.  According to visual observations made
from a helicopter at 14:00 on July 25 (S. Zharinov and O. Braitseva),
the gas and ash plume rising from the summit is as high as 3 km above
the crater or 8 km ASL and extending to the northwest.  Lava flows
from the summit crater extend down the western slope of the volcano,
entering and melting the glacier at about 3 km ASL.  Seismic activity
including tremor is stable but at a high level.

According to additional helicopter observations made on July 26, the
height and direction of the plume was about the same.  Ashfall took
place in the city of Klyuchi.
