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.

The major eruption of Raususan about 4,200 years ago was similar in several ways to the 1980 Mount St. Helens eruption. Flank collapse produced a debris avalanche and left a crater that opens to the west. Pyroclastic flows accompanied growth of a lava dome in the new crater. This dacite dome (right) forms the high point. Several geothermal areas occur on the flanks of the central cone.

Brightly-colored deposits of elemental sulfur surround fumarolic vents on the NW side of the central cone of Mendeleev volcano, in the southern Kuril Islands. These fumaroles are located within several craters where the central cone meets the inner caldera wall. Hot springs occur on the NE flank and along the NE coast, where the Goriachi-Pliazh geothermal field is located.

Raususan contains two nested calderas, the larger is 6-7 km in diameter and the smaller is 3-3.5 km in diameter. A cone that formed inside the younger caldera is seen here from the E, near the settlement of Yuzhno-Kurilsk. A phreatic explosion was recorded in 1880. The Goryachy Plyazh geothermal field is located outside the caldera along the Pacific coast.

Raususan on the southern part of Kunashir Island towers above the village of Yuzhno-Kurilsk. Steam plumes are visible rising from geothermal wells on the NW flanks, one of several geothermal fields across the volcano. The edifice seen in this view is within a 6-7 km wide caldera.
