Koshelev, Kamchatka, Russia
Location: 51.357N, 156.75E
Elevation: 5,943 ft. (1,812m)
Koshelev, also known as Chaokhch, is a compound stratovolcano with a
very large caldera that was formed in Pre-glacial time. The cone
continued to erupt into the Post-glacial era. On the badly eroded western
slope are very active solfataras, on the eastern side are
cinder cones with basaltic flows, and to the west is the
Sea of Okhotsk. At Koshelev's summit there are two craters. The eastern
crater is fresh and active, the northwestern has apparently not erupted
for a long time and is becoming an erosion caldera. Scientists believe
that at the end of the 17th century Koshelev erupted with large
explosive eruptions. Some other volcanoes in this area are:
