An earthquake of 7.5 magnitude struck in the Pacific Ocean off southeastern Alaska yesterday.

The quake occurred about 100 km southwest of Port Alexander at a depth of about 10 km at 9.58am, according to the US Geological Survey, which downgraded the magnitude from an initial 7.7.

The West Coast and Alaska Tsunami Warning Centre in Palmer, Alaska, issued a tsunami warning for coastal areas of southeast Alaska and Canada’s British Columbia, but this was later cancelled.

So far there were no reports of damage from the earthquake, tsunami warning centre scientist Bill Knight said.

Officials in Sitka, southern Alaska, were urging evacuations in low-lying areas, local radio station KCAW reported.

An earthquake of magnitude 7.7 struck British Columbia on October 27. A tsunami warning was issued but no damage ensued.
