Moderate fumarolic activity

Between 12 October and 2 November 1986, moderate fumarolic activity was observed in the E part of the summit crater. The fumaroles fell along a N-S line that divided the crater. The rest of the crater was snow-covered.

Increased thermal activity

Recent aerial infrared surveys and ground investigations have shown increasing thermal activity at Fuss Peak. Gorshkov (1967) reported that there was no fumarolic activity at the volcano, E. K. Markhinin found only very minor signs of it in 1969, and fumaroles were not observed during 1971-1976 overflights. In 1973, an aerial infrared survey detected weak thermal anomalies over an area of about 104 m2 in the N and E parts of the crater and on its E rim (Gusev and Zelenov, 1979). When the volcano was resurveyed in 1978, intense thermal anomalies were measured over most of the 700-m-diameter crater, extending down to its bottom about 200 m below the rim. Weak fumaroles were observed in the E and central part of the crater. The 1978 resurvey also found a 50-80 m-wide zone of anomalously high temperatures extending 250-300 m down the E flank from the crater rim (Gusev and Zelenov, 1979). Fumaroles were seen on the E flank during an overflight in the fall of 1981.

G. S. Steinberg visited the volcano in September 1982 and found fumaroles at the base of both the W and E sides of the crater's small median ridge. Activity was stronger at the E base of the ridge, where there were two groups of fumaroles, each with three powerful vapor jets with temperatures of 95-96°C. Bright yellow sulfur crystals were present in some of the vents. Despite the fumaroles, the majority of the crater floor was snow-covered. Many weak fumaroles were observed in a zone of small fissures on the upper flank in the immediate vicinity of the crater rim, but none had deposited sulfur. About halfway down the cone, in a narrow, shallow canyon that was apparently an extension of the upper flank fissure zone, there were three groups of fumaroles, separated by 30-60 m, vigorously emitting a mixture of steam and other gases. Temperatures at these vents were 94-96°C and they had deposited bright yellow sulfur. Within the fissure zone, temperatures at 30-40 cm depth were 9-13°C. Temperatures at similar depths outside the zone were 3-4°C.

Fuss Peak in the distance forms a peninsula on the SW coast of Paramushir Island. This isolated symmetrical, 1772-m-high stratovolcano has a 700-m-wide, steep-walled crater that is 300 m deep. Well-preserved lava flows occupy the middle and lower flanks, particularly on the east and SE sides. Only one unambiguous historical eruption is known from Fuss Peak, in 1854. A volcanological field party in the foreground examines wave-rounded boulders on the shore of Shirinki Island.

The dramatic symmetrical cone of Fuss Peak forms a peninsula on the SW coast of Paramushir Island, the largest of the Kurils. This isolated 1772-m-high stratovolcano has a 700-m-wide, steep-walled crater that is 300 m deep. The NW rim of the crater is deeply notched to the level of the crater floor, which is drained by the canyon that is seen here descending diagonally to the right as far as the coast. Only one unambiguous historical eruption is known from Fuss Peak, in 1854.
