A magnitude 6.2 earthquake struck northern Japan early on Monday, the Japan Meteorological Agency (JMA) reported. The tremor occurred 18km west of Sarabetsu, a small town on Hokkaido, Japan’s northernmost main island, at a depth of 81km.
No damage or casualties were immediately confirmed, and the JMA issued no tsunami advisory. The inland quake came just a week after a 7.7 magnitude offshore earthquake prompted a warning for a slightly elevated risk of a potential mega-quake—one measuring 8.0 or higher—in northeastern coastal areas.
The JMA stated that Monday's earthquake was outside the specific mega-quake warning zone and that the special awareness period would conclude as scheduled.
