Japan was shaken near Ishinomaki, Ishinomaki Shi, Miyagi, by an earthquake of magnitude 5.1 only 7 minutes ago, Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED) reported.
The quake hit at a moderately shallow depth of 57.50 km beneath the epicenter near Ishinomaki, Ishinomaki Shi, Miyagi, Japan, early morning on Monday, December 1st, 2025, at 2:25 am 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.
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 Ishinomaki (pop. 140,200) located 52 km from the epicenter, Shiogama (pop. 52,700) 70 km away, Tagajo-shi (pop. 62,800) 73 km away, Tome (pop. 77,900) 81 km away, Natori-shi (pop. 78,700) 83 km away, Sendai (pop. 1,096,700) 84 km away, Sendai (pop. 1,096,700) 84 km away, and Osaki (pop. 128,800) 86 km away.

Monitoring of the activity in the Los Coconucos volcanic chain indicates the following, according to the Colombian Geological Survey (SGC), an entity under the Ministry of Mines and Energy:
Since the alert level of the Puracé volcano was raised to Orange, and up to the time of this report, seismic signals associated with fluid movement—specifically volcanic tremor (TR) and long-period (LP) events—have continued. These signals reflect the ongoing release of volcanic gases. Some have been linked to minor ash emissions, with their dispersion influenced by shifting wind patterns. Notably, at 4:06 a.m. on November 30, a continuous tremor signal corresponded to an ash-and-gas column rising more than 500 meters above the summit of Puracé, although adverse weather prevented full visibility on other monitoring
