A 6.2-magnitude earthquake struck northern Japan early Monday, with no immediate reports of damage or casualties.
The Japan Meteorological Agency said no tsunami advisory was issued.
The quake struck 18 kilometers (11 miles) west of the small town of Sarabetsu on Japan’s northernmost main island of Hokkaido at a depth of 81 kilometers (50 miles), according to the US Geological Survey. It measured the quake’s strength at 6.1 magnitude.
A week ago, a 7.7 magnitude earthquake prompted Japan to issue an advisory of a slightly higher risk of a possible megaquake for the nation’s northeastern coastal areas.
