Iliinsky volcano at sunrise above the NE shore of Kurile Lake, was constructed beginning about 8,000 years ago within a 4-km-wide caldera of about the same age as the Kurile Lake caldera. It is one of several visible from the shores of one of Kamchatka's most scenic lakes. Its latest eruption, in 1901, created a 1-km-wide crater on the NE flank. The 10-km-wide Kurile Lake caldera was the source of one of Kamchatka's largest Holocene explosive eruptions about 7,600 years ago.

Volcanologists from the Institute of Volcanic Geology and Geochemistry in Petropavlovsk and the New Mexico Institute of Mining and Technology excavate a section through layered tephra deposits from Ilyinsky volcano in southern Kamchatka. Detailed study of the products of individual eruptions are used to determine the timing, frequency, and magnitude of those eruptions. The sequence of tephra layers shown here was deposited by explosive eruptions from Ilyinsky during the last 5,000 years.

The maar crater in the foreground formed during an eruption in 1901 on the NE flank of Iliinsky volcano. Light-colored tephra was deposited around the rim of the crater and cover the flanks of the volcano. At the end of the eruption lava was extruded on the floor of the 200-m-deep, 1-km-wide crater. Zheltovsky is the volcano to the left of this image.

A 1-km-wide maar was formed in 1901 on the NE flank of Iliinsky. The northern wall of the crater exposes areas of light-colored hydrothermally altered rocks at the base that are surrounded by talus deposits. The darker bedded layers above this are tephra fall deposits of ash and scoria from earlier eruptions of Iliinsky. The light-colored layers (upper left) on the rim of the crater are tephra fall and pyroclastic surge deposits.

The bedded layers in this photo are tephra fall and pyroclastic surge deposits produced by successive explosions during the formation of a maar on the NE flank of Iliinsky in 1901. This eruption created a new crater 800 x 1,000 m wide and 200 m deep that opens to the NE.

Zheltovsky rises across a valley NE of Iliinsky volcano. The flat shelf on the right flank is the eastern rim of a 4 x 5 km, largely buried Pleistocene caldera. The western rim of a smaller, late-Holocene caldera forms the break in slope on the left side just below the summit lava dome complex. The crater in the foreground is a NE-flank maar of Iliinsky that formed in 1901.

Iliinsky, seen here from the NW, was constructed beginning about 8,000 years ago within a 4-km-wide caldera about the same age as the adjacent Kurile Lake caldera. A period of explosive volcanism during the mid-Holocene lasted 1,000-1,500 years. Growth of the modern cone was completed during the late Holocene. Lava flows cover much of the northern flanks and a 1901 eruption produced a 1-km-wide crater on the NE flank.

Iliinsky volcano, seen here across Kurile Lake from the SW at the outlet of the Ozernaya River, was constructed during the past 7,600 years above the NE rim of Kurile Lake caldera. The flat ridge with a steep terminus on the left horizon consists of north-flank lava flows that were emplaced about 1,500-2,000 years ago.
