Popocatepetl volcano (Mexico) - Smithsonian / USGS Weekly Volcanic Activity Report for 17 May-23 May 2023 (New Activity / Unrest)

CENAPRED reported that activity at Popocatépetl intensified during 16-23 May after recent activity characterized by the formation of small to medium lava domes on the summit crater floor and their subsequent destruction. There were 154-168 daily steam, gas, and ash emissions and minor-to-moderate explosions during 16-19 May. Periods of high-frequency tremor lasted more than 12 hours during 16-17 May and more than 10 hours during 17-18 May. ... Read all

Background:

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.
