Shiveluch erupts, sends ash up to 5 km, Kamchatka

Shiveluch erupts, sends ash up to 5 km, Kamchatka

Local Emergencies Ministry department confirmed that Shiveluch volcano, Kamchatka, spewed ash to a height of up to 5 km (3 miles) on Monday, August 5, 2013. The cloud of ash moved in the eastern direction from the volcano bypassing residential areas at the distance of some 50 km. 

VD reported that an explosion and/or dome collapse event occurred on August 2 at 19:36 UTC, with a likely ash plume rising to possibly up to 20,000 ft (estimated from seismic signals).

Although the current eruption poses no immediate threat to nearby settlements, ash fallouts could be dangerous to health, environment and air traffic.

Based on visual observations and analyses of satellite data, KVERT reported that during July 19 - 26 a viscous lava flow effused on the N flank of Shiveluch's lava dome, accompanied by hot avalanches, incandescence, and fumarolic activity. Satellite images detected a daily thermal anomaly. Based on analyses of satellite images, the Tokyo VAAC reported a possible eruption on July 27. Ash was detected in images the next day. The VAAC also noted that, according to the Kamchatka Branch of Geophysical Services (KBGS; Russian Academy of Sciences), ash plumes rose to altitudes of 6.1 - 6.4 km on July 27 and 29 (GVP).

Ash eruptions had begun at Shiveluch in 1999 and were accompanied by long-term growth of a lava dome with occasional block-and-ash flows.
