Popocatépetl Volcano Volcanic Ash Advisory: PSBL VA EMS

Published: 15 September 2025
Categories: Global Volcano Activity

RSS feed source: US National Weather Service

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

The United States Geological Survey reported a magnitude 3.4 quake in the United States near Antioch, Contra Costa County, California, only 9 minutes ago. The earthquake hit early afternoon on Monday, September 15th, 2025, at 3:00 pm local time at a very shallow depth of 4 miles. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by The Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 3.5 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.5.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Clayton (pop. 11,900) located 5 miles from the epicenter, Antioch (pop. 110,500) 5 miles away, Pittsburg (pop. 69,400) 6 miles away, Brentwood (pop. 59,000) 8 miles away, and Oakley (pop. 39,800) 8 miles away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Concord (pop. 128,700) located 10 miles from the
