Volcanos

Roundup of Global Volcanic Activity:

Kizimen (Kamchatka): The lava dome remains active and produces hot avalanches on the western and eastern flanks. KVERT reports moderate seismic activity, incandescence of the volcano summit and medium to strong degassing.

Shiveluch (Kamchatka): The activity of the growing lava dome continues with little changes. KVERT reports moderate seismic activity, moderate gas-steam activity and incandescence.

Tolbachik (Kamchatka): According to the latest KVERT report, the eruption has gained again in strength. Tremor levels have risen and lava continues to effuse from the southern fissure vent, feeding a broad lava flow field.

Pavlov (Alaska Peninsula, USA): The eruption continues with lava fountaining, an active lava flow and ash emissions, accompanied by continuous seismic tremor. Aerial observations suggest that the interaction of lava and ice on the upper slope of the volcano create mud flows and pyroclastic flows. A narrow plume of steam, ash, and gas, occasionally up to 20,000 ft. above sea level, and extending southeast from the volcano over the North Pacific Ocean was visible in satellite images yesterday. Minor to trace ash fallout could be occurring on the north, east and southeast flanks of the volcano and possibly on parts of Pavlov Bay and adjacent waters southeast of the volcano. Nearby communities have not reported any ash fall over the past 24 hours. (AVO)

Popocatépetl (Central Mexico): Activity remains elevated, but the number and size of explosions have decreased during the past 2 days. CENAPRED made an overflight and found that the series of recent explosions since 14 May, in particular the two that occurred on the night of the 16th to 17th, have excavated a crater of approx. 200 m diameter and 40 m depth in the lava dome. The rest of the dome's surface is covered by fragments from the explosions.
