Latest news from Sarychev Peak:
Wednesday, Aug 14, 2019
SVERT reported that an ash plume from Sarychev Peak rose to 2.7 km (9,000 ft) a.s.l. and drifted 50 km SE on 11 August, based on Tokyo VAAC notices. The Aviation Color Code was raised to Yellow.

Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 9000 ft (2700 m) altitude or flight level 090 and is moving at 15 kts in SE direction. ...
This once-in-a-lifetime spectacular image was shot from the International Space Station on June 12, 2009 and shows an early stage of one of the larger eruptions at Sarychev Volcano.
The eruption plume is composed of brown ash and white steam. The vigorously rising plume gives the steam a bubble-like appearance; the surrounding atmosphere has been shoved up by the shock wave of the eruption. The smooth white cloud on top may be water condensation that resulted from rapid rising and cooling of the air mass above the ash column.

2009 subplinian eruption
Sarychev volcano has a spectacular eruption on 12-15 June 2009. A powerful explosion produced an sub-plinian eruption column 12-18 km tall which injected large amounts of ash into the stratosphere. The plume extended 200 km to the south-west and 105 km to the south-east. The eruption was mainly observed through satellites, because Sarychev is not monitored with ground-based instruments. The eruption intensified on 14 June, when the column reached 40,000 ft (13 km), and on 15 June, when it peaked at 54,000 ft (18 km) altitude.
A new eruption began at Sarychev volcano on 14 January 1989. The eruption was preceded by a magnitude 6.2 earthquake near nearby Simushir Island.
During an overflight on 2 November 1986, a lava flow was observed extending 150 m south of the crater.
Ash emissions were observed from Sarychev Peak in September 1976.
A series of explosions destroyed the old lava dome. Ash plumes extended 300 km to the NNE. At the end of the eruption, lava flows occurred.
Small ash eruptions occurred from Sarychev volcano.
A large eruption occurred in 1946. Big bombs were ejected as far as 7 km from the crater and the height of the ash emissions reached more than 6 km.
The eruption in 1930 was a large explosive event lasting 13 hours.
The eruption of Sarychev in 1928 was explosive.
During the eruption in 1878-79, a lava flow was erupted.
The eruption in 1760 was one of the largest of Sarychev Peak in historic times.
