AB: Bezymianny (55.9°N, 160.6°E, ~2900 m elevation) is an active, explosive volcano within the Central Kamchatka Depression (CKD), Kamchatka Peninsula, Russia. Based on information from the Kamchatka Volcanic Eruption Response Team (KVERT 2006), an explosive eruption occurred at Bezymianny Volcano, Kamchatka, Russia at 09:17 UTC on 24 December 2006. This produced an ash cloud up to ~10 km ASL. We investigate the 24 December 2006 eruption using rapid-response data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), combined with field photographs of the deposit. Furthermore we consider thermal and textural observations on the deposits. Satellite images agreed with aerial photographs taken on 27 December 2006 showing the warm deposit (relative to the snow) concentrated in the south-eastern channel. We present data from rapid response images collected in conjunction to the Alaska Volcano Observatory (AVO) and suggest inferences toward future activity.
