Activity of Sheveluch, Turrialba, Colima and Sinabung.

On December 9th, the Sheveluch experienced a strong explosive episode which was accompanied by a plume of ashes rising to 11,000 meters asl. The ash then diverted to the NNE in the direction of Ozernovsky Bay, an uninhabited area.
The ash cloud was spotted by the satellites up to 910 km of the volcano.
After the explosion, only a thermal anomaly is reported.
The aviation alert turned red between 9.12 to 22.35 UTC and 10.12 to 5.38 UTC, before remaining orange.

Turrialba was the site of an eruption on 9 December at 9.34 local, accompanied by a column of ashes rising 500 meters above the crater, drifting towards the NO. The bad weather conditions did not allow to get good pictures of the webcams.

Teletica speaks of modification to the crater following the recent activity: the crater would have deepened, and would pass from 70 meters in 2014 to 100 meters in 2016. Following inflation, the volcano would have grown by 5 cm. approximately per year.
