A 6.7 magnitude earthquake shook northeastern Japan Friday, producing small tsunami waves but no immediate reports of serious damage.
The quake struck off the east coast of Aomori prefecture on Honshu at a depth of about 12 miles, the Japan Meteorological Agency said. Authorities issued a tsunami advisory that was lifted roughly two hours later.
Small waves were recorded along parts of Hokkaido and Aomori prefectures. There were no reports of significant injuries or major structural damage.
The Friday quake came days after a stronger 7.5 magnitude earthquake Monday in the same general area, which caused injuries, light damage and a small tsunami along Japan’s Pacific coast.
No tsunami alerts were issued for the U.S. West Coast or Hawaii.
Monday’s temblor, also off Aomori, left at least 34 people injured and damaged roads and buildings. Some Pacific coast communities saw tsunami waves of up to about 28 inches.
In response, Japan issued a megaquake advisory Tuesday estimating that an offshore megaquake could produce a tsunami up to about 98 feet and potentially cause nearly 200,000 deaths. Officials stressed the advisory was not a prediction and put the chance of a magnitude 8 or larger event at about 1%.
Authorities said the advisory was intended as a wake-up call to boost preparedness for a catastrophic event similar to the 2011 disaster that killed nearly 20,000 people and destroyed a nuclear plant.
Seismologists noted that Monday’s quake temporarily raised risks in Hokkaido and along the Sanriku coast, where the Pacific Plate forms the Japan and Chishima trenches—areas that have produced many large earthquakes in the past.
