Most Recent Weekly Report: 4 June-10 June 2014


SVERT reported that an eruption at Chirinkotan had begun on 24 May; thermal anomalies and gas emissions sometimes containing ash were detected in satellite images. On 5 June seldom and weak thermal anomalies suggested cooling lava flows. The Aviation Color Code was lowered to Green.

Most Recent Bulletin Report: December 2013 (BGVN 38:12)


Gas-and-steam emissions and occasional thermal anomalies, beginning May 2013

In 1979-1980, an eruption at Chirinkotan included a series of ash explosions and a lava flow (SEAN 05:06). In October and November 1986, airborne observers saw a column of thick gas and ash, and then fumarolic activity (SEAN 12:04). This report discusses events during 2013 through April 2014. The location of Chirinkotan in the Kuril Islands is shown in figure 1.

According to the Sakhalin Volcanic Eruption Response Team (SVERT), gas-and-steam emissions occurred frequently in 2013-2014 (table 1). The Aviation Color Code was Green on 24-25 May 2013, when emissions were first reported, but raised to Yellow during early June 2013, where it has remained through April 2014, the end of this report. The volcano was often obscured by clouds.

According to the U.S. Geological Survey, an M 8.3 earthquake occurred on 24 May 2013 beneath the Sea of Okhotsk, at a point is 656 km N of the volcano. The focal depth of the earthquake was ~ 600 km. The first reported gas-and-steam emission from Chirinkotan, which is in the Sea of Okhotsk, was on 24-25 May, suggesting a possible link between the two events.

Bulletin Reports

All information contained in these reports is preliminary and subject to change.


06/1980 (SEAN 05:06) Lava flows and ash explosions

In April 1979, an eruption began from Chirinkotan volcano, which forms an isolated, uninhabited island about 3 km in diameter. Block lava flowed down the SSW flank in April and May. Ash explosions occurred regularly during the summer of 1979 and explosive activity increased in October. In January and April 1980, moderate explosions occurred 1-2 times per hour.

04/1987 (SEAN 12:04) Ash and gas columns observed

Chirinkotan was observed from the air 11, 12, and 31 October, and 2 November. A thick gas and ash column reached 700-800 m above the crater, and drifted 6-8 km downwind on 11 October. Intense gas emission occurred throughout the crater. On 12 October gas emission was less intense but a gas cloud reached 400-600 km high and was 3-4 km long despite a strong wind. By 31 October fumarolic activity had diminished significantly. On the E crater slope a few groups of large fumaroles were observed. A gas plume 200 m in diameter was 250 m high and 800-900 m long. Flank ashfall had been covered by snow that fell 12-13 October. Activity was similar on 2 November.

The small, mostly unvegetated 3-km-wide island of Chirinkotan occupies the far end of an E-W-trending volcanic chain that extends nearly 50 km west of the central part of the main Kuril Islands arc. Chirinkotan is the emergent summit of a volcano that rises 3000 m from the floor of the Kuril Basin. A small 1-km-wide caldera about 300-400 m deep is open to the SE. Lava flows from a cone within the breached crater reached the north shore of the island. Historical eruptions have been recorded at Chirinkotan since the 18th century. Fresh lava flows also descended the SE flank of Chirinkotan during an eruption in the 1880s that was observed by the English fur trader Captain Snow.

The small, mostly unvegetated 3-km-wide island of Chirinkotan is the emergent summit of a volcano that rises 3000 m from the floor of the Kuril Basin. Submarine terraces are lacking around the island, suggesting the edifice is of Holocene age. Chirinkotan lies at the far end of an E-W-trending volcanic chain that extends nearly 50 km west of the central part of the main Kuril Islands arc. Historical eruptions have been recorded at Chirinkotan since the 18th century, including one observed by the English fur trader Captain Snow.

Large Eruptions of Chirinkotan Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
WOVOdat WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
EarthChem EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).
