Earthquake swarm associated with geothermal production
A summit earthquake swarm with focal depths of <10 km was recorded 4-5 May 1987 (table 9-1). Epicenters were <15 km from Yuzhno-Kurilsk seismic station (12 km from the volcano). Repeated measurements 25-28 September in a borehole 10 km from the summit registered temperatures 4°C higher than in 1986 at a depth of 74 m. Temperatures increased 4-5°C in some hot springs on the E and S flanks. Fumaroles in the same area showed essentially no variation from 1986; vapor emitted under pressure had temperatures of 97-107°C. . . . the earthquakes seemed to be caused by exploitation of geothermal wells, used for heat production.

Raususan, also known as Mendeleev, is a low compound stratovolcano located in the southern part of Kunashir Island. The dominantly andesitic-dacitic volcano is cut by two nested calderas, the larger 6-7 km in diameter and the smaller 3-3.5 km. A central cone that formed inside the younger caldera was breached to the west by a large debris avalanche about 4200 years ago. A lava dome that grew inside the avalanche scarp forms the 888 m high point of the volcano. Additional lava domes in the northern part of the older caldera are considered to represent flank activity of the younger caldera. The only unambiguous historical eruption was a small phreatic explosion in 1880. Four solfatara fields lie at the eastern and northern flanks of the central cone, and a geothermal field is located outside the caldera along the eastern coast.

| The last major eruption of Mendeleev volcano, about 4200 years ago, was similar in several regards to the 1980 Mount St. Helens eruption. Collapse of the central cone produced a debris avalanche and left a horseshoe-shaped crater breached to the west. Pyroclastic flows accompanied growth of a lava dome in the new crater. This dacitic dome (right) forms the 887-m high point of Mendeleev volcano. Steam rises above a NW-flank fumarolic area (center), one of several thermal areas on the flanks of the central cone.

| Brilliantly colored deposits of elemental sulfur surround fumarolic vents on the NW side of the central cone of Mendeleev volcano, in the southern Kuril Islands. Fumarolic areas on Mendeleev are associated with lateral craters at this location and at several areas from the NE to SE flanks, where the central cone meets the inner caldera wall of Mendeleev. Hot springs occur on the NE flank and along the NE coast, where the Goriachi-Pliazh geothermal field is located. Photo by Yuri Doubik (Institute of Volcanology, Petropavlovsk). |

| Mendeleev, also known as Rausu-dake, is a compound stratovolcano with two nested calderas, the larger 6-7 km in diameter and the smaller 3-3.5 km. A central cone that formed inside the younger caldera is seen here from the east, near the settlement of Yuzhno-Kurilsk. The only unambiguous historical eruption was a small phreatic explosion in 1880. The Goriachy Pliazh geothermal field is located outside the caldera along the Pacific coast.

| Mendeleev volcano on the southern part of Kunashir Island towers above the village of Yuzhno-Kurilsk. Steam plumes rise above geothermal wells on the volcano's NW flanks, in one of several geothermal fields flanking the volcano. The volcano seen here lies within a 6-7 km wide caldera. The only unambiguous historical eruption from Mendeleev was a small phreatic explosion in 1880. Photo by Alexander Rybin, 2001 (Institute of Marine Geology and Geophysics, Yuzhno-Sakhalin). |
