Based on satellite data, KVERT reported that Kambalny was quiet on 1 April. Explosions on 2 April generated ash plumes that rose to an altitude of 7 km (23,000 ft) a.s.l., and then minor ash emissions occurred at least through 6 April. Ash plumes drifted 200 km E and SE during 2-4 April, and a thermal anomaly was identified in satellite images during 3-4 April. The Aviation Color Code remained at Orange.
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.
