Dear colleagues!
Volcanological experience of Bezymianny volcano study to allow KVERT staff to predict this eruption.
On May 20, 2010 I sent you my letter:
"According to satellite data by AVO and KVERT staff, a temperature of
the thermal anomaly over the lava dome of Bezymianny volcano began
increasing from May 19 (from -1 (9:49 UTC) to +18 (15:52 UTC) degrees of C).
the thermal anomaly over the lava dome of Bezymianny volcano began
increasing from May 19 (from -1 (9:49 UTC) to +18 (15:52 UTC) degrees of C).
Possibly a new lava block extrudes at the lava dome of Bezymianny.
And this stand for a preparation of new strong explosive eruption of Bezymianny volcano.
Possibly this explosive eruption of Bezymianny volcano can occurs during May 21 - May 30 or May 21 - June 10."
