International Space Station Imagery
Avachinsky Volcano, Kamchatka Peninsula, Russia
high res (0.8 M) low res (57 K)
ISS027-E-020395 (2 May 2011) --- Avachinsky Volcano, Kamchatka Peninsula, Russia is featured in this image photographed by an Expedition 27 crew member on the International Space Station. The Kamchatka Peninsula, located along the Pacific "ring of fire", includes more than 100 identified volcanoes. While most of these volcanoes are not actively erupting, many are considered to be dangerous due to their past eruptive history and proximity to population centers and air travel corridors. This detailed photograph highlights the summit crater and snow-covered upper slopes of the Avachinsky stratovolcano exposed above a surrounding cloud deck. The 2,741-meter-high Avachinsky volcano has an extensive historical and geological record of eruptions with the latest activity observed in 2008. The large city of Petropavlovsk, Kamchatka is located approximately 25 kilometers to the southwest and, according to scientists, is built over approximately 30,000 -- 40,000 year old debris avalanche deposits that originated from Avachinsky -- suggesting that the city may be at risk from a similar hazard in the future. To the southeast (right), the large breached crater of Kozelsky Volcano is also visible above the clouds. Kozelsky is a parasitic cone, formed by the eruption of material from vents along the flank of Avachinsky volcano. The topography of the volcanoes is accentuated by shadows produced by the relatively low sun angle, and by the oblique viewing angle. Oblique images are taken looking outwards at an angle from the International Space Station, rather than the "straight down" (or nadir) view typical of most orbital Earth-observing sensor systems.
