At the Agung, the plumes of ashes succeed one another more and more rapidly; the BNPB reports thirty this December 10 between 00h and 18h local, thick and reaching 1,000 to 2,000 meters above the summit.
The rains remobilized the ashes emitted by the volcano and generated lahars in the villages of Telaga Waja, Apet and Tangkup.

The 12th eruption of the year 2017 began this December 10 in the Fuego, characterized by moderate to strong explosions, on average 12 times per hour, and a plume of ash reaching 5,000 meters asl., traveling for 15 km on a large south sector.
A lava fountain, 500 meters high above the crater, produces ballistic falls more than 300 meters away, small avalanches in the Las Lajas, Cenizas and Taniluya barrancas, as well as a 1,500 meter lava flow. length in the Seca / Santa Teresa barranca.
The explosions are accompanied by shock waves and fallout of ashes on La Rochela, San Andres Osuna, Panimaché, Morella.

Activity appears to be decreasing in Villarica, where POVI reports the stabilization of the crater bottom at about 70 meters depth, and five days without spattering observation; seismicity and incandescense are also down
A seismic swarm marks the Skjaldbreidur shield volcano since 9 December. This volcano, located north-east of Lake Thingvellir, is part of the Oddnýjarhnúkur - Langjökull system, in the West Rift zone.
More than 100 earthquakes have been counted, including at least 4 of magnitude between 3 and 4.
It is by no means an awakening of the Skjaldbreidur, the nature of the seismic activity would be purely tectonic, without signs of magmatic movements for the moment. One can however notice its position directly under the main crater, where may remain a residual magmatic reservoir.
