KLYUCHEVSKOY VOLCANO, Kamchatka, Russia 56o11'N, 160o47'E Thursday, July 15, 1993, 23:30 KDT The summit eruption continues to occur. Lava fountaining is characteristic for this volcano and is currently occurring to heights up to 1 km above the crater rim. Gas and steam bursts are producing a dark, ash-laden plume that, based on seismicity, may be rising to a height of several km above the crater rim. However, the summit is obscured by clouds and plume height is unconfirmed. Volcanic tremor with amplitude of 2.5 mkm (5.6 mkm maximum) is being registered by Krestovskii seismic station located as far as 19 km from the volcano. Zelyonaya station (11 km from the volcano) is recording signals with an average amplitude of 13.5 mkm (25 mkm maximum).
