Magnitude 3.9 earthquake strikes near Elko, Elko County, Nevada, USA

An earthquake of magnitude 3.9 occurred in the evening on Friday, August 29th, 2025, at 9:54 pm local time near Elko, Elko County, Nevada, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 3.6 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 3.9 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.9.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Valmy (pop. 37) located 30 miles from the epicenter, Battle Mountain (pop. 3,600) 36 miles away, Carlin (pop. 2,300) 48 miles away, and Winnemucca (pop. 7,900) 50 miles away. In Elko (pop. 20,300, 59 miles away), the quake was probably not felt.

Popocatépetl Volcano Volcanic Ash Advisory: PSBL VA EMS

Published: 29 August 2025

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
