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 European-Mediterranean Seismological Centre (EMSC) reported a magnitude 3.2 quake in Switzerland near Bern, Bern-Mittelland District, Canton de Berne, only 24 minutes ago. The earthquake hit in the afternoon on Tuesday, July 22nd, 2025, at 5:51 pm local time at a shallow depth of 10. km. 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 citizen-seismograph network of RaspberryShake, which listed it as a magnitude 3.0 earthquake. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 3.0, France’s Military Applications Division – Earth and Environmental Science (CEA) at magnitude 3.4, and the Swiss Seismological Service (SED) at magnitude 3.2.
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 Wilderswil (pop. 2,300) located 3 km from the epicenter, Unterseen (pop. 5,200) 3 km away, and Unterseen (pop. 5,200) 3 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking

A moderately shallow magnitude 3.8 earthquake was reported in the morning near Fritz Creek, Kenai Peninsula, Alaska, USA.
According to the United States Geological Survey, the quake hit on Tuesday, July 22nd, 2025, at 7:41 am local time at a moderately shallow depth of 22 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.
Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 3.8 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.8.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Fox River (pop. 690) located 10 miles from the epicenter, Fritz Creek (pop. 1,900) 22 miles away, Diamond Ridge (pop. 1,200) 32 miles away, Homer (pop. 5,500) 33 miles away, Anchor Point (pop. 1,900) 40 miles away, and Cohoe (pop. 1,400) 43 miles away. In Kalifornsky (pop. 7,900, 46 miles away), and Kenai (pop. 7,700, 54 miles away), the quake was probably not felt.
