A fairly shallow 4.8 magnitude earthquake was reported in the early hours of the morning near Kamaishi, Kamaishi-shi, Iwate, Japan.
According to the Japan National Research Institute for Earth Sciences and Disaster Resilience (NIED), the earthquake occurred on Thursday July 1, 2021 at 06:44 local time at a fairly shallow depth of 52.4 km. The exact magnitude, epicenter, and depth of the quake may be revised in the next few hours or minutes as seismologists review the data and refine their calculations, or when other agencies issue their reports.
Based on preliminary seismic data, the quake should have caused no significant damage, but may be felt by many as a light tremor in the epicenter area.
Weak tremors may be felt at Kamaishi (pop. 43,100) which is 22 km from the epicenter, Tsuchi (pop. 16,500) 25 km, Yamada (pop. 20,100) 31 km, funato (pop. 35,400) 38 km, Miyako (pop. 51,700) is 50 km away, and Tōno (pop. 26,800) is 51 km away.

If you feel this earthquake (or if you are near the epicenter), please share your experience and submit a short “I feel it” report! Other users will be happy to hear that!
Too if you DO NOT feel the earthquake even if you are in the area please report! Your contribution is also valuable for earthquake science and earthquake hazard analysis and mitigation efforts. You can use device location or a map to show your location during an earthquake. Thank you!
Info: The more agencies report about the same earthquake and post similar data, the more trust you can have in the data. It usually takes up to several hours for earthquake parameters to be calculated with near optimal precision.
