Popocatépetl volcano (Mexico), activity update: elevated tremor and glow suggesting rise of magma

Friday Aug 07, 2020 08:30 AM | BY: T

Glow and steam/ash emissions from Popo volcano this morning (image: CENAPRED webcam)

Over the past weeks, the activity of the volcano has remained essentially unchanged at moderate levels.
It is characterized by occasional vulcanian-type explosions (0-3 per day), a larger number (typically 20-40) passive emissions of steam and ash, as well as constant glow from the crater visible at night.
At the end of July 2020, daily volcanic tremor duration increased to approx. 1000 min / day around which value it has been fluctuating during the past 10 days. This as well as the visible glow and near-constant emissions of gas and small amounts of ash suggest continued rise of fresh magma probably accumulating as a new lava dome in the inner summit crater.

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.
