Koryaksky at the NASA Earth Observatory

Russian volcano Koryaksky on the Kamchatka peninsula has been active recently, along with quite a few of its fellow Kamchatkan volcanoes. Earlier today NASA’s Aqua satellite passed overhead and its Moderate Resolution Imaging Spectroradiometer (MODIS) captured Koryaksky volcano producing a diffuse white plume which blows away to the east. The resulting image can be found at the NASA Earth Observatory.

The city of Petropavlovsk-Kamchatsky (population 200,000) is overlooked by Koryaksky and Avachinsky volcanoes, both highly active – the image above shows clearly just how close Koryaksky is to the city. Koryaksky has been designated a Decade Volcano jointly with Avachinsky because of its history of explosive eruptions and its proximity to populated areas.

Koryaksky: 4-kilometre eruption plume reported 17 August 2009

The Russian news agency Itar-Tass is reporting that the Kamchatkan volcano Koryasky is erupting and producing a 4-kilometre-high plume:

Koryaksky volcano … is ejecting columns of vapor, gas and ash to the altitude of about 4,000 meters above sea level. The trail of gas and ash extends over a distance of almost 20 kilometers. Experts from the Kamchakta Volcanic Eruption Response Team told Itar-Tass the eruption does not pose any threat to nearby population centers.

Tokyo VAAC issued an advisory for Koryaksky early today also reporting ash to about 4 km (13000 feet). Current webcam images (around 16:00 GMT) show a small plume and diffuse ash clouds around the peak.

The KVERT updates page at the Alaska Volcano Observatory reports that the volcano is now at Orange alert status (‘explosive eruption is possible within a few days and may occur with little or no warning’).

[UPDATE: there is an archive of Koryaksky webcam images at the University of Alaska – thanks to Stefan of Stromboli.org for pointing this out in the comments below.]

Images from a video camera monitoring Koryaksky volcano on the Kamchatka Peninsula in eastern Russia are available via the Kamchatkan Volcanic Eruption Response Team (KVERT) website. Click on the link below to access the Koryaksky webcam page.

The latest updates for Koryaksky report that strong fumarolic activity continues, and ash explosions up to 6km above sea level are possible. Seismicity at the volcano remains at background levels. Recent images of Koryaksky can be found on this page of the KVERT website.

Koryaksky causing alarm 29 December 2008

Koryaksky volcano on the Kamchatka Peninsula has been showing signs of heightened activity recently, as we reported here at The Volcanism Blog on 26 December. Now comes news that Petropavlovsk-Kamchatky Airport has been closed to flights and that the Russian volcanological authorities are warning of a possible explosive eruption. A report from RIA-Novosti quotes Alexei Ozerov of the Volcanology and Seismology Institute of the Russian Academy of Sciences:

‘Compared to the eruption of 1956 – the only one to have been observed in this volcano’s history – the eruption under way now began much more rapidly and powerfully … the authorities in the province and the city of Petropavlovsk must be prepared for more powerful eruptions and take steps to monitor the volcano and aviation safety.’

The same report indicates that the reason for the heightened alert is a new vent about 3.1-3.3 kilometres above sea level (Koryaksky’s summit elevation is 3.456 km), at a point where fumarolic activity has been observed over a long period. The current alert level is given by KVERT as orange, which is the second-highest level, and the most recent KVERT bulletin on Koryaksky reports a moderate explosive eruption, ash plumes rising to 4.0km, no seismic data ‘for technical reasons’, and expects the activity of the volcano to increase.

Russian news reports speak of a volcanic ash hazard for aircraft: a local news report today says that dark ash emissions are rising to 4.0km above sea level. The Tokyo Volcanic Ash Advisory Center has no current ash alerts for Koryaksky, but ash at low altitudes could well be dangerous for the operation of airports in the vicinity of the volcano, hence the closure.

With neigbouring Avachinsky, Koryaksky has been designated a Decade Volcano because of its history of explosive eruptions and its proximity to populated areas.

[N.B. You’ll also see this volcano called Koryak. The cataloguers at the Global Volcanism Program call it Koryaksky, and as with other volcanoes it’s the GVP nomenclature that is used on this blog.]
