An earthquake of magnitude 4.7 occurred 30 minutes ago 70 km southeast of Laoang, Philippines, the citizen-seismograph network of RaspberryShake reported.
The quake hit at a shallow depth of 10. km beneath the epicenter near Laoang, Northern Samar, Eastern Visayas, Philippines, in the afternoon on Friday, October 31st, 2025, at 4:57 pm local time. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Alugan (pop. 2,100) located 19 km from the epicenter, San Policarpo (pop. 3,600) 20 km away, and Arteche (pop. 5,000) 23 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Oras (pop. 9,000) located 28 km from the epicenter, Gamay (pop. 9,100) 34 km away, Dolores (pop. 9,300) 35 km away, Laoang (pop. 16,700) 70 km away, and Borongan (pop. 16,500) 83 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you’re in the area, please send us your experience through our

Popocatépetl Volcano Volcanic Ash Advisory: OCSL VA CLD OBSD to 20000 ft (6100 m)

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
