Volcanoes and earthquakes make Russia even bigger 17 November 2009

Posted by admin in Russia, Sarychev Peak.

Already the largest country on the planet, Russia has become even bigger over the past couple of years thanks to the workings of plate tectonics in the Russian Far East. Sakhalin Island was struck by earthquakes on 2 August 2007 (some pictures  here) which added ~3 square kilometers of new territory through uplift, while lava flows from the Sarychev Peak eruption of June 2009 (stunning image here) enlarged Matua Island in the Russian Kurils by 1.5 square kilometres.

The appearance of new land through volcanism has caused international tension in the past, but fortunately there are no such complications this time.

Sarychev Peak SO2 emissions 13 July 2009

A sulphur dioxide cloud emitted by Sarychev Peak volcano in the central Kurils can be seen on the NOAA Kamchatka map compiled from OMI (Ozone Monitoring Instrument) data early today:

OMI_SO2 Column 5Km by Volcano - Kamchatka, 13 July 2009 0231Z (NOAA, OMI data). Click on image to enlarge.
[Click on the image above to enlarge.]

The SVERT update on Sarychev Peak for 13 July 2009 reports low-level activity with gas emission but no ash explosions: ‘According to satellite images from today, (MODIS 0907130031UTC), (NOAA 17 0907122247 UTC) ash-gas emission is observed at Sarychev volcano. It stretches east 40 km’. The gas cloud visible in the north-west of the Sea of Okhotsk is the residue of that emitted by Sarychev Peak earlier this month (e.g., see the update on 9 July 2009).

[Thanks to Volcanism Blog reader Gijs de Reijke for spotting this SO2 data.]

Sarychev Peak update, 24 June 2009 24 June 2009

The eruption at Sarychev Peak in the Kurils appears to be on the wane, with no visible emissions cloud reported in the latest Volcanic Ash Advisory from Tokyo VAAC, issued at 02:52 GMT yesterday, 23 June 2009.

The Sakhalin Volcanic Eruption Response Team reported a steam and gas plume extending 120 km south of the volcano on 20 June, a ‘high’ (1.5 km altitude) steam and gas emission stretching 7 km north-west and an intense thermal anomaly on 21 June, a steam and gas plume extending 29 km north at 1.5 km altitude on 22 June, and a 9-km-long steam and gas plume extending north-west and an intense thermal anomaly on 24 June.

Incidentally SVERT also notes possible ‘increasing of steam-gas activity’ at Severgin volcano in its 22 June bulletin, and a thermal anomaly at the same volcano on 24 June. Severgin was the central cone of a volcano on the island of Kharimkotan in the northern Kurils, which destroyed itself in a VEI=5 eruption in 1933. This, the GVP notes, was ‘one of the largest [eruptions] in the Kuril Islands during historical time’. The island shows evidence of repeated slope-failures and collapses precipitating debris avalanches into the sea. The 1933 collapse of Severgin produced a tsunami that reached Paramushir, ~150 km to the north.

Stunning Sarychev Peak picture from the NASA Earth Observatory 19 June 2009

Sarychev Peak eruption, Kuril Islands, 12 June 2009 (ISS astronaut photograph/NASA Earth Observatory)

The people at the NASA Earth Observatory have been doing a wonderful job of covering the current eruption at Sarychev Peak in the Kuril Islands, but they have really excelled themselves with their latest image: this stunning astronaut photograph of the volcano taken from the International Space Station on 12 June 2009, at an early stage of this eruption. There’s so much of interest to talk about here: the dark ashy plume punching upwards through the atmosphere almost vertically (little shearing wind at this stage), the pileus or cap of white cloud atop the plume, the pyroclastic flows ringing the volcano’s peak, and the neat circle in the surrounding cloud that has been the focus of much discussion among commenters over at Eruptions. Mostly, though, one just wants to sit back and look at this picture and go ‘WOW’.

Here’s a detail taken from the large version of the image. The light-coloured pyroclastic flow descending the volcano’s flanks towards the bottom of the image is an absolute beauty:

The original (un-rotated and un-cropped) image can be found at the Gateway to Astronaut Photography of the Earth.

NASA Earth Observatory: Sarychev Peak eruption, Kuril Islands (18 June 2009)

[Date corrected to 12 June - got so excited over the image, I'd put July. Thanks, Martin!]

UPDATE: The image above is just one of thirty pictures of the eruption taken from the International Space Station. Boris Behncke has submitted a very helpful comment explaining how to get hold of all of them via the Gateway to Astronaut Photography: check out his comment below for the instructions.

FURTHER UPDATE (25 June 2009): This dramatic image has achieved very wide coverage across the media since the NASA Earth Observatory featured it, and the ‘circle in the clouds’ around the eruption column in particular has attracted a lot of comment and debate. At the original Earth Observatory page for the image an editorial comment has been added summarizing the different interpretations of this phenomenon (scroll down to ‘Editor’s note’) without coming down in favour of any particular explanation. Here at The Volcanism Blog we’ll have more to say about this image tomorrow next week (been very busy, sorry).
