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

An earthquake of magnitude 4.7 occurred early morning on Saturday, August 16th, 2025, at 5:47 am local time near Quito, Provincia de Pichincha, Ecuador, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at a shallow depth of 10. km. 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.
Our monitoring service identified a second report from the Institute of Geophysics of the National Polytechnic School in Quito (IGEPN) which listed the quake at magnitude 5.1. Other agencies reporting the same quake include The Colombian Geological Service (SGC) at magnitude 4.2, and the citizen-seismograph network of RaspberryShake at magnitude 4.8.
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 Sangolqui (pop. 5,100) located 27 km from the epicenter, Machachi (pop. 25,700) 34 km away, Quito (pop. 2,781,600) 41 km away, Pomasqui (pop. 28,700) 53 km away, Cayambe (pop.
