An earthquake of magnitude 5.0 occurred only 7 minutes ago 77 km southeast of Ofunato, Japan, Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED) reported.
The quake hit at a moderately shallow depth of 63.40 km beneath the epicenter near Ofunato, Ōfunato-shi, Iwate, Japan, around noon on Monday, October 13th, 2025, at 12:25 pm local time. 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 4.6 earthquake.
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 Ofunato (pop. 35,500) located 77 km from the epicenter, Rikuzen-Takata (pop. 18,300) 77 km away, Kamaishi (pop. 43,100) 87 km away, and Ishinomaki (pop. 138,500) 95 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ichinoseki (pop. 114,500) located 113 km from the epicenter.

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
