Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): The situation has remained more or less unchanged. Etna has been quiet except intense degassing from the NE crater and a faint plume from the NSEC. There are currently no signs of the expected next paroxysm at the New SE crater and tremor has decreased overall during the past days (of course, this can change quickly).

Klyuchevskoy (Kamchatka): Low-level ash emissions continue.

Nishino-shima (Volcano Islands, Japan): Activity has decreased significantly over the past days. A video from 10 December shows no more strombolian explosions, only degassing and no significant changes to the size of the island compared to a week ago. It is possible that there is still weak effusion of lava, but it appears that the eruption could have come to an end.

Sinabung (Sumatra, Indonesia): No ash emissions have been detected during the past 48 hours, the crater shows only a degassing plume, but alert level remains at red, because new explosions could occur any time. The government has extended the emergency status until at least 21 December, which implies that the more than 17,000 evacuees remain in the total of 31 shelters. Their situation is difficult, with help needed in form of food, water, medicines and sanitary supplies.

Merapi (Central Java): Another small phreatic explosion occurred at the summit lava dome this morning at 08:10 local time. it produced an ash plume rising 500 m. According to VSI, rainwater infiltration into the hot rocks of the dome caused the eruption.
