The European-Mediterranean Seismological Centre (EMSC) reported a magnitude 5.3 quake in the Philippines near Mati, Davao Oriental, Davao, only 9 minutes ago. The earthquake hit early evening on Saturday, August 9th, 2025, at 7:33 pm local time at an intermediate depth of 100.50 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 5.2 earthquake. Other agencies reporting the same quake include the Philippine Institute of Volcanology and Seismology (PHIVOLCS) at magnitude 5.7, and the German Research Centre for Geosciences (GFZ) at magnitude 5.2.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
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 Tibanbang (pop. 7,800) located 78 km from the epicenter, Sigaboy (pop. 8,000) 81 km away, Caburan (pop. 12,600) 92 km away,

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
