Shiveluch, Russia

KVERT reported that seismic activity at Shiveluch was above background levels during 20-27 March. Based on interpretations of seismic data, ash plumes likely rose to an altitude of 6 km (19,700 ft) a.s.l. According to observers, fumaroles were active during 23-26 March and explosions produced ash plumes that rose to an altitude of 8 km [...]

Ashfall from Shiveluch Volcano, Kamchatka

NASA’s Earth Observatory recently posted this amazing image of ashfall from Shiveluch.
The Shiveluch (sometimes spelled Sheveluch) Volcano is the most active of the arc of volcanoes that dot northeast Russia’s Kamchatka Peninsula. Lava domes build and collapse fairly regularly in the caldera, sending cascades of ash and debris down the slopes. In the first week [...]
