After a gradual increase in strombolian activity in recent weeks, Stromboli has seen a sharp increase in all its parameters on 15 December from 1040 GMT, including seismic and infrasonic activity, which characterizes intense projections to the northeast crater.

An increase in the flow of sulfur dioxide and detected around 9:40, with 182 tonnes / day for the crater NE.

Around 13:25 GMT, an overflow of lava begins on the outer edge of the northeastern crater, of limited extension. This activity corresponds to the thermal anomaly of 13 MW observed from 12:25 GMT by Mirova Modis.

In Fuego, the activity remains at a high level, with 5 to 8 explosions per hour, generating plumes of gray ash at 4,700-5,000 meters asl, before dispersing to the west and southwest on 20 km.

Falls of fine ash are observed on Panimache I, Morelia, Santa Sofía and el Porvenir.

At Agung, the activity remains similar to that of previous days. Lava effusions continue slowly, interspersed with emissions of a gray-white plume up to 1,500 meters above the summit.

In Sinabung, in absence of a PVMBG report this morning, one can only note a significant explosive activity on the evening of the 15th and on the 16th of December at the beginning of the day, according to the photos of local observers.
