Moscow: Meteorological authorities in Japan didn't issue any tsunami alerts while US authorities cancelled a warning for Hawaii after a 7.5 magnitude earthquake struck off Russia's Kuril Islands.
The US Pacific Tsunami Warning Center also said the country's West Coast, Alaska and Canada's British Columbia didn't face any tsunami danger from the quake.
Some of the US coastal areas may experience non-damaging sea level changes, the agency added.
The Japan Meteorological Association also said there might be slight tidal changes but said no warnings or even watch advisories had been issued.
A 7.5 magnitude earthquake struck near Russia's far eastern Kuril Islands on Wednesday and a tsunami warning was issued for the closest shores.
The U.S. Geological Survey said the quake struck 219 kilometers south-southeast of Severo on the Kuril chain north of Japan. It was 56 kilometers (37 miles) deep.
The Pacific Tsunami Warning Center said hazardous tsunami waves were possible within 1,000 kilometers of the quake's epicenter.
It said earthquakes of this strength in the past have caused tsunamis far from the epicenter, and the U.S. National Tsunami Warning Center was analyzing the event to determine the level of danger.
