Shiveluch (3,307m), one of two Kamchatka’s most active and most continuously erupting volcanoes is awake again. Tourists are warned to stay clear from the area as it is extremely dangerous. The volcano’s activity grew after 29 July Alaska’s earthquake, local volcanologists said. Video via Kamchatka1
Shiveluch Smokes Once Again
The Shiveluch volcano is erupting once again. It is one of the largest and most active volcanoes in Kamchatka Krai, a territory in northeast Russia. At least 60 large eruptions have occurred at Shiveluch in the past 10,000 years. The Operational Land Imager on Landsat 8 acquired an image of the latest eruption on February 23, 2019.
The Kamchatkan Volcanic Eruption Response Team (KVERT) reported growth in the lava dome (a mound formed by viscous magma piling up around the volcano’s vent) from February 8-15, 2019. Additionally, satellite images detected thermal anomalies daily. News outlets reported ash plumes reaching as high as 6 kilometers (4 miles) on February 21. In the image above, the plume is traveling northeast, throwing a shadow to the north of the volcano.
As of February 25, explosive activity continues. The Volcanic Ash Advisory Center (VAAC) Tokyo warned of additional volcanic ash plumes at altitudes approaching 4 kilometers. KVERT reports ongoing activity could affect low-flying and international flights.

KVERT reported that the growth of the lava dome at Sheveluch continued during 14-24 August, accompanied by strong fumarolic activity, dome incandescence, and hot avalanches. A thermal anomaly was identified in satellite imagery all week. Gas-and-steam plumes containing some ash drifted 370 km SW, E, and SE. On 21 and 24 August ash plumes rose to 4 km (13,100 ft) a.s.l. and drifted 86 km SE and 3.5 km (11,500 ft) a.s.l. and drifted as far as 100 km SE, respectively. The Tokyo VAAC reported ash plumes during 17-25 August that rose to 3.7-5.5 km (12,000-18,000 ft) a.s.l. and drifted E, S, SE. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).
