All times are local (unless otherwise noted)

The last major eruption at Kambalny volcano was around 1350, although younger undated tephra layers have been found; there are also five Holocene cinder cones on the W and SE flanks. According to the Kamchatkan Volcanic Eruption Response Team (KVERT), a new eruption began began at about 2120 UTC on 24 March 2017. Satellite data showed an initial ash plume at about 5-6 km altitude drifting about 35 km SW from the volcano.

Explosive activity was strong during 24-27 March, generating ash plumes up to 7 km high that drifted downwind as far as 2,000 km (table 1). Activity then decreased, with only minor ash emissions through 6 April, followed by ash plumes that drifted 50 and 170 km on 9 and 10 April, respectively. Only gas-and-steam plumes were reported after that time.

On 25 March satellite imagery showed an ash plume stretching about 100 km SW of the Kamchatka Peninsula (figure 1). A dark stain is visible to the W of the plume, where ash has covered the snow. By 26 March ashfall had covered the ground on both sides of the volcano. The eruption was also observed on the ground by staff at the South Kamchatka Federal Wildlife Sanctuary (figure 2). The Ozone Monitoring Instrument on the Aura satellite observed an airborne plume of sulfur dioxide (SO2) trailing S of Kamchatka on 26 March 2017 (figure 3).

On 28 March 2017, the Operational Land Imager (OLI) on the Landsat 8 satellite acquired a natural-color image of an ash plume from Kambalny (figure 4), including a large area of ash-covered snow. When photographed by scientists on 12 April (figure 5), the entire edifice was covered by ash and there was a gas-and-steam plume rising from a crater fumarole.

Geologic Background. The southernmost major stratovolcano on the Kamchatka peninsula, Kambalny has a summit crater that is breached to the SE. Five Holocene cinder cones on the W and SE flanks have produced fresh-looking lava flows. Beginning about 6,300 radiocarbon years ago, a series of major collapses of the edifice produced at least three debris-avalanche deposits. The last major eruption took place about 600 years ago, although younger tephra layers have been found, and an eruption was reported in 1767. Active fumarolic areas are found on the flanks of the volcano, which is located south of the massive Pauzhetka volcano-tectonic depression.
