A tsunami warning has been issued for Hawaii after an 8.2 magnitude earthquake struck off the Alaska Peninsula.
Alerts were issued for the US state, as well as the Peninsula and Pacific coastal areas from Hinchinbrook Entrance to Unimak Pass, but threats to Guam and American Samoa were later revised down.
The quake struck at 10.15pm on Wednesday local time, at a depth of 46.7, the US Geological Survey said.

The earliest estimated arrival of the first tsunami in Hawaii is 12.53am local time (10.45am GMT).
Preliminary seismic data suggests the quake would have been widely felt by almost everyone in the area of the epicentre and might have caused light to moderate damage.
An alert issued by the US Tsunami Warning System said: “Based on all available data a tsunami may have been generated by this earthquake that could be destructive on coastal areas even far from the epicenter.
“An investigation is underway to determine if there is a tsunami threat to Hawaii.
“Further messages will be issued hourly or sooner as conditions warrant until the threat to Hawaii has passed.”
The impacts may be felt as far as Australia and New Zealand with the UTWS predicting waves “less than 0.3 meters above the tide level” in these areas.
