and western sides of the crater
lake is a wall of ice. On the northern side a tephra wall rises
20 meters
above the water. The ice walls at the southwestern corner of the crater
are melting, i.e. at the site of the vent that was active 4 – 6 June. The
rate of melting is assumed to be about one cuber
meter per second.
