Gorely

Kaldera · Russia · 1799 m

Part of the summit complex of Gorely is seen in this view from the S. It was constructed within a large caldera and contains 11 summit and 30 flank craters. Historical eruptions, largely consisting of moderate Vulcanian and phreatic explosions, have commonly produced ash plumes that are visible from Petropavlovsk, Kamchatka's largest city.

Ringkasan geologi

Gorely volcano consists of five small overlapping stratovolcanoes constructed along a WNW-ESE line within a large 9 x 13 km caldera. The caldera formed about 38,000-40,000 years ago accompanied by the eruption of about 100 km3 of tephra. The massive complex includes about 40 cinder cones, some of which contain acid or freshwater crater lakes; three major rift zones cut the complex. Another Holocene stratovolcano is located on the SW flank. Activity during the Holocene was characterized by frequent mild-to-moderate explosive eruptions along with a half dozen episodes of major lava extrusion. Early Holocene explosive activity, along with lava flows filled in much of the caldera. Quiescent periods became longer between 6,000 and 2,000 years ago, after which the activity was mainly explosive. About 600-650 years ago intermittent strong explosions and lava flow effusion accompanied frequent eruptions. Historical eruptions have consisted of moderate Vulcanian and phreatic explosions.

Gorely is a volcano located in the southern part of the Kamchatka Peninsula, Russia. It consists of five overlapping stratovolcanoes and is one of the most active in southern Kamchatka. Gorely is a large, long-lived shield-type volcano that is currently in an eruptive phase. Prior eruptions occurred in 1980-81 and 1984–86.Several complexes compose the overall volcanic structure:ancient Pra-Gorely volcano which measures 20–25 km in diameter; a 12 km diameter caldera; thick stratum of ignimbrites totaling a volume of 100 km3; post-caldera eruption cinder cones; modern edifice – “Young Gorely” composed of three large superimposed cones and 11 associated craters forming a NW-SE trending intra-caldera ridgeline; a complex of 40 modern subsidiary cones on the slopes of “Young Gorely”.
