AN earthquake of 7.5 magnitude struck in the Pacific Ocean off south-eastern Alaska yesterday.

The quake occurred about 60 miles south-west of Port Alexander at a depth of about six miles at 8.58am GMT, according to the US Geological Survey, which downgraded the magnitude from an initial 7.7.

The West Coast and Alaska Tsunami Warning Centre issued a tsunami warning for coastal areas of southeast Alaska and Canada's British Columbia, but this was later cancelled. So far there had been no reports of damage.
