The Sernageomin / OVDAS recorded on December 6 from 3:20pm a seismic swarm in Copahue; 200 volcano-tectonic earthquakes, associated with rock fracturing, occurred 6.2 km at the ENE of thecrater El Agrio.

The strongest earthquake, from ML 3.1, is recorded at 15:56 at a depth of 4,600 meters.

The superficial activity of the volcano is characterized as the days before by a plume of gas and fine particles at a height of about 800 meters.

The alert level remains in Amarillo.

At Popocatépetl, we notice, besides the exhalations, an explosion on December 6th at 1:17 pm; it was accompanied by a plume of gas, steam and ash that rose to 2,500 meters above the summit, before dispersing to the northwest.

The growth of the Merapi dome continues at the rate of 2,200 m³ per day, a little down between November 29 and yesterday. The summit dome reached the volume of 244,000 m³ on December 6th.

A thick whitish plume is observed 50 meters above the summit.

The seismicity of 06.12 is characterized by 52 eruption earthquakes, 14 emission earthquakes, 11 low frequency earthquakes and one hybrid earthquake.

The activity level remains at 2 / waspada
