A magnitude 5.2 earthquake near Tsukuba, Tsukuba Shi, Ibaraki, Japan, was reported only 7 minutes ago by Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a moderately shallow depth of 51.10 km beneath the epicenter early evening on Friday, December 12th, 2025, at 7:05 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 4.9 earthquake.
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 Tsukuba (pop. 175,600) located 4 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Tsukuba (pop. 241,700) located 13 km from the epicenter, Shimodate (pop. 63,700) 14 km away, Chikusei (pop. 100,800) 15 km away, Tsuchiura (pop. 144,400) 18 km away,
