Magnitude 5.3 earthquake strikes near Tsukuba, Tsukuba-shi, Ibaraki, Japan
5.3 quake 2 Dec 1:58 am (GMT +9)
5.3 quake 2 Dec 1:58 am (GMT +9)
A moderately shallow magnitude 5.3 earthquake was reported early morning near Tsukuba, Tsukuba-shi, Ibaraki, Japan.
According to Japan's National Research Institute for Earth Science and Disaster Resilience (NIED), the quake hit on Thursday, December 2nd, 2021, at 1:58 am local time at a moderately shallow depth of 64.9 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 German Research Centre for Geosciences (GFZ), which listed it as a magnitude 5.1 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 Shimodate (pop. 63,700) located 9 km from the epicenter, Tsukuba (pop. 175,600) 10 km away, Yūki (pop. 51,600) 13 km away, Oyama (pop. 159,900) 19 km away, Iwai (pop. 42,500) 21 km away, Koga (pop. 58,000) 25 km away, Ushiku (pop. 80,000) 31 km away, Mito (pop. 246,500) 44 km away, Tokyo (pop. 8,336,600) 65 km away, and Yokohama (pop. 3,574,400) 93 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 reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
