No fumarolic activity

During an aerial survey on 2 November 1986 the summit crater [of Krenitzyn] was covered with snow. There was no indication of fumarolic activity in the summit area or in the area of the 1952 E-flank eruption.

Information Contacts: G. Steinberg and B. Piskunov, Yuzhno-Sakhalinsk.

A large symmetrical post-caldera cone, 1325-m-high Krenitzyn Peak, forms a 4-km wide island that towers above the rim of 7.5-km-wide Tao-Rusyr caldera. A 350-m-wide crater caps the peak, and a large shallow lateral crater (left center) is located on the upper NE flank. The small dark mass along the eastern shoreline (right-center) is a lava dome that was emplaced in 1952 during the only historical eruption of the volcano. Kal'tsevoe lake fills a caldera that was formed about 7500 years ago during one of the largest Holocene eruptions in the Kuril Islands.

Summer snow remnants highlight dendritic drainages cutting pyroclastic-flow deposits on the flanks of Tao-Rusyr caldera on Onekotan Island in this NASA Space Shuttle image (with north to the left). The 7.5-km-wide caldera was formed about 7500 years ago accompanied by the eruption of 30-35 cu km of tephra during one of the largest Holocene eruptions of the Kuril Islands. Subsequently Krenitzyn Peak stratovolcano was constructed in the NW part of the caldera, reaching a height well above the caldera rim.
