Kamchatka Peninsula, Russia - August 17th, 2009

The Kamchatka Peninsula in eastern Russia has a high density of volcanoes and associated volcanic phenomena, with 19 active volcanoes being included in the six UNESCO World Heritage List sites in the Volcanoes of Kamchatka group. Many of these volcanoes can be seen in detail in this orthorectified image.

Kronotsky, a major stratovolcano with a particularly symmetrical conical shape, comparable to Mount Fuji in Japan, can be observed at the edge in the upper right corner, east of Lake Kronotsky. The summit crater is plugged by a volcanic neck.

Moving southwest, one comes to Krasheninnikov, two overlapping stratovolcanoes inside a large caldera. To their west is another volcanic caldera, 9 by 12 km, called Uzon, which hosts a large geothermal field.

Nearer to the coast, below these calderas, are several other volcanoes and the Valley of Geysers, the second largest concentration of geysers in the world. This valley is a 6 km long basin containing approximately ninety geysers.

Moving southwest into the lower left quadrant, Karymsky Lake appears as a dark black circular area. This lake is actually a water-filled volcanic caldera that is part of the Akademia Nauk Volcano.

To the northeast of the lake is Maly Semiachik, a compound stratovolcano located in a 10-km-wide caldera within the 15 by 20 km Stena-Soboliny caldera. Three overlapping stratovolcanoes were constructed sequentially along a NE-SW line, with the youngest cone, Ceno-Semiachik, at the southwest end. A hot, acidic crater lake fills the historically active Troitsky Crater, which formed during a large explosive eruption of Ceno-Semiachik about 400 years ago

Directly north of Karymsky Lake is the Karymsky Volcano, the most active volcano of Kamchatka’s eastern volcanic zone. It is a symmetrical stratovolcano constructed within a 5-km-wide caldera that formed during the early Holocene. Much of the cone is mantled by lava flows less than 200 years old.
