Tsunami warning for Alaska, BC and Washington State.

A 7.5-magnitude earthquake hit off Russia’s Kuril Islands on Wednesday, the US Geological Survey said, prompting a tsunami warning.

The quake hit at a depth of 59km (37 miles), around 1,400km north-east of the Japanese city of Sapporo, USGS added. There were no early reports of casualties.

The Pacific Tsunami Warning Centre said hazardous tsunami waves were possible within 1,000km of the quake’s epicentre. It said earthquakes of this strength in the past had caused tsunamis far from the epicentre and the US National Tsunami Warning Centre was analysing the event to determine the level of danger.

“This earthquake has the potential to generate a destructive tsunami in the source region,” it said.
