Introduction
The Asacha group is a complex massif of Pleistocene-to-Holocene volcanoes located within a distinctly fault-bounded crustal block WSW of Mutnovsky volcano. An ancestral Asacha shield volcano, Zheltyi stratovolcano to the east, a younger Asacha stratovolcano, and the small Tumanov lava cone (the best-preserved major cone of the Asacha volcano group) were constructed during the late Pleistocene. Ten lava domes dot the flanks of the Asacha volcanoes. Most of these were formed during the Pleistocene, but some may be early Holocene in age. Also during the Holocene, basaltic cinder cones and lava flows related to regional volcanism were erupted along the western and southern flanks of the Asacha complex. A major volcano-tectonic earthquake swarm occurred near Zheltyi volcano in 1983, suggesting that the complex remains volcanically active.---
