MT. KLYUCHEVSKOY and MT. BEZYMIANNY VOLCANOES 56o11' N, 160o47' E January 3, 1994, 18:00 KST (0600) Spasmodic volcanic tremor was registered on December 30 (11:30 UT) and December 31 (00:31 UT) at seismic station "Zelyonaya" (11 km from Klyuchevskoy and 16 km from Bezymianny) with maximum amplitude of 0.7 micron. The weak shallow earthquakes occurred at the same time. This seismic activity was also recorded at stations "Podkova", "Krestovskaya" and in Klyuchi town. The source of the seismic events is uncertain because of the lack of seismic stations. The pattern of seismic activity is more characteristic of Klyuchevskoy volcano. A large steam and gas plume was visible at Bezymianny volcano extending for 40 km to the northeast. The usual fumarolic emission was observed from the central crater of Klyuchevskoy volcano.
