Activity of Popocatépetl, Metis shoal / Lateiki and Shishaldin.

The explosive activity of Popocatépetl was intense early in the night of November 4, after a quieter day marked by 92 low-level exhalations and an explosion at 00:38, which watered the flanks of incandescent fragments over 2 km and produced a plume ash of about 1,500 meters.

Explosions occurred at 21:58 and 22:19, the latter marked by a strong incandescence and projections to more than one km. crater.

At 00:09 this November 5th, an explosion was accompanied by a plume of ash 1,000 meters high, with a dispersion to the northwest.

Some images of the progression of the activity between October 15 and October 30, 2019, recovered by the Satellite Sentinel-2.

At Shishaldin, the eruption continues; the lava overflows the crater and feeds a flow on the north-west flank in elongation. This one developed in two branches on November 3rd (doubling already visible on the image of 01.11.2019 - article of yesterday), each of them extending on approximately 1.000 meters.

Debris flows / lahars also extended, extending up to 2 km on the north and south flanks;

Sporadic glow is observable at night on webcams, and satellites show hot spatter deposits on the summit cone in relation to explosive activity and / or fountaining.

Small explosions are observed on the seismic and infrasonic networks.

The volcanic alert remains at Watch and the aviation code at orange
