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

A shallow magnitude 3.2 earthquake was reported early morning near Rhodes, Dodecanese, South Aegean, Greece.
According to the National Observatory of Athens (NOA), the quake hit on Tuesday, May 20th, 2025, at 6:55 am local time 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 Aristotle University of Thessaloniki Geophysical Lab. (AUTH) which listed the quake at magnitude 2.8. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 3.2.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Archangelos (pop. 5,400) located 10 km from the epicenter, Afantou (pop. 5,600) 15 km away, Lardos (pop. 1,300) 18 km away, Faliraki (pop. 6,000) 20 km away, Maritsa (pop. 1,800) 23 km away, Koskinou (pop. 4,900) 25 km away, Ialysos (pop. 11,300) 28 km away, Kremasti (pop. 4,700) 29 km away, and Rhodes (pop. 56,100) 31 km away.
