The volcanic ash advisory center (VAAC) Tokyo issued a warning this morning for ash hazard up to FL270 (8.2 km) extending south-west which by now has dissipated. KVERT has the volcano on orange alert and estimated the height of the ash plume to 13120-16400 ft (4-5 km) above sea level. The plume was barely visible on todays Aqua/Modis (NASA) image.

KVERT also reports that the growth of the lava dome continues, accompanied by moderate ash explosions, fumarolic activity, incandescence of the dome summit and hot avalanches.

On his blog Peter Webley shows an animation of the eruption seen on the EMSD webcam located about 50 km south-west of Shiveluch in the town Klyuchi.

As I am writing there are several columns of steam or smoke rising from the southern base of the volcano seen on the KVERT webcams. My personal impression is that they arise from the border a fresh avalanche or lava flow, but they might as well be from, as KVERT wrote, fumarolic activity or something unrelated to volcanic activity.

Looking at earthquakes under the Kliuchevskaya, or northern or group of volcanoes one can see almost continuous activity at 30 km depth under Kliuchevskoy which appears to be the major source feeding the conduits to the volcanic edifices.

Below Shiveluch the seismicity of the past month does not seem out of the ordinary viewed at this level of detail:

For further reading and background information I highly recommend reading Ukviggen´s “Shiveluch, the bad boy of Kamchatka” and part two again. And for the tectonic background read Sa´ke´s post about the Central Kamchatka Depression. Also check out KVERT´s image gallery.

  1. And for those who are enjoying the football madness, since the Swedish team basically suck we did not get to go. So, instead we are sending a football anthem. It is in the language of “Europeisch”…

    • FED was a bit restless, but other than that, it seems quite like an error or some artificial activity around the station.
