A magnitude 6.1 earthquake struck off Hokkaido in northern Japan on Saturday night time, the US Geological Survey and the Japan Meteorological Company mentioned.

No tsunami warning was issued after the offshore quake, which shook the coastal cities of Kushiro and Nemuro.

Main Japanese media retailers carried no quick reviews of injury or accidents.

The quake hit at 10:27 pm (1327 GMT) at a depth of round 43 kilometres (27 miles), the USGS mentioned.

An skilled talking on public broadcaster NHK warned residents to be vigilant in opposition to quakes for a few week.

Earthquakes are frequent in Japan, which sits on the Pacific “Ring of Fireplace”, an arc of intense seismic exercise that stretches by Southeast Asia and throughout the Pacific basin.

The nation has strict building rules meant to make sure buildings can stand up to robust earthquakes, and routinely holds emergency drills to arrange for a significant jolt.
