SO2 plume from Popocatépetl yesterday (NOAA)

Current seismic recording from Popocatépetl

The intensity of the current eruptive phase remains high. A phase of particularly strong tremor accompanying continuous explosions and ash emissions occurred this morning.
As a consequence of the elevated activity,CENAPRED raised the alert level to Yellow, Phase 3. An exclusion zone of 12 km radius around the volcano is in place.
During the (intermittent) eruptions, an steam and ash plume is rising about 3 km above the crater.
A giant SO2 plume can be seen drifting north from Popocatepétl, which is notorious of its large SO2 output during eruptions.

Popocatépetl volcano (Mexico): strong continuous explosions

A phase of strong eruptive activity has started last night and is continuing with frequent explosions that eject incandescent bombs onto the upper outer slope and create a plume of gas and ash rising 3-4 km above the volcano to flight level 250 (25,000 ft). ... Read all

Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America's 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano.
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time.
