At 10:55 a.m. on February 22, the San Miguel / Chaparrastique volcano emitted an ash cloud over a period of 10 minutes. The cloud has reached a maximum of 400 meters above the level of the crater; at least two pulses were observed, in the form of a small column of ash and gas

During this period, the seismic amplitude recorded in the VSM station located in the upper part of the north flank of the volcano, reached 510 units in ten minutes on average, 150 units being normal. The recording of the earthquakes occurred shows that they were generated continuously, corresponding to volcanic tremor. After this event, until the publication of this report, the volcano maintained a slight degassing of its crater.

 

This scenario could continue over the next few days, without excluding a higher energy process, which could generate higher columns and more ash.

Residents, tourists and mountaineers should stay away from the volcano crater, due to small explosions with ash fumes that the volcano presents, which can lead to the release of gas and ash in a southwest direction , transported by preferential winds.

While remaining within the framework of the Amarillo Fase 2 volcanic alert, the Popocatépetl experienced an exhalation on February 22 in the evening, accompanied by an ash plume reaching approximately 800 meters, heading west.

On February 23 at 12:44 am, an explosion was accompanied by expulsion of incandescent fragments on the sides and plume at a height of 1,000 meters in a northeast direction.
