KVERT reported that seismic activity in the area of Gorely and Mutnovsky volcanoes decreased during 15-18 June. Moderate fumarolic activity was observed on 17 June; no activity was noted or cloud cover obscured views the other days during 14-20 June. The level of Concern Color Code was lowered to Green on 20 June.

KVERT reported that seismic activity in the area of Gorely and Mutnovsky volcanoes increased on 13 June. There is only one seismic station in the area of the two volcanoes, so the source of the seismicity could not be determined. Activity was not visually noted and satellite imagery was not available at the time of the seismicity increase. The level of Concern Color Code was raised to Yellow on 14 June.

KVERT reported on 11 January that seismic activity in the area of Mutnovsky and Gorely volcanoes was slightly elevated above background levels during the previous three weeks, but increasing activity was not confirmed. There is only one seismic station in the area of the two volcanoes so the source of the seismicity cannot be determined. Activity was not observed on satellite imagery. The level of Concern Color Code was lowered to Green.

The Concern Color Code at Mutnovsky was reduced from Yellow to Green during 3-10 June. There were no significant changes in volcanic activity during the week. A thermal anomaly was observed at the volcano on satellite imagery, possibly due to the heat from a thermal field.

Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

Massive Mutnovsky, one of the most active volcanoes of southern Kamchatka, is formed of four coalescing stratovolcanoes of predominately basaltic composition. Multiple summit craters cap the volcanic complex. Growth of Mutnovsky IV, the youngest cone, began during the early Holocene. An intracrater cone was constructed along the northern wall of the 1.3-km-wide summit crater. Abundant flank cinder cones were concentrated on the SW side. Holocene activity was characterized by mild-to-moderate phreatic and phreatomagmatic eruptions from the summit crater. Historical eruptions have been explosive, with lava flows produced only during the 1904 eruption. Geothermal development is planned at Mutnovsky, which has the highest heat capacity of any volcano in the Kuril-Kamchatka arc.
