Magnitude 8.2 quake hits in Gulf of Alaska

A shallow magnitude 8.2 earthquake has the Gulf of Alaska, putting a huge area of the North Pacific on alert for a potentially destructive tsunami.

The quake hit 256km southeast of Chiniak, Alaska. It was 10 kilometres deep and hit at 12.31am (10.31pm NZ time), the US Geological Survey said.

"If you are located in this coastal area, move inland to higher ground. Tsunami warnings mean that a tsunami with significant inundation is possible or is already occurring," Anchorage Office of Emergency Management said in a warning for Alaska and British Columbia.

The quake hit about 10.30pm New Zealand time.

The Pacific Tsunami Warning Centre (PTWC) issued warnings for parts of Alaska and Canada, a tsunami watch for the entire US west coast and Hawaii.

The tsunami warning for Hawaii has now been removed. 

"Tsunami sirens just went off in Kodiak, Alaska," one user on Twitter wrote. Kodiak would be one of the first in line for a tsunami.

"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 epicentre," the PTWC said.

Japan's meteorological agency said it was monitoring the situation but did not issue a tsunami alert.

Coastal inundation (flooding of land areas near the shore) is NOT expected.

Strong currents and surges may be experienced for the 24 hour period from midday, 24th January.

New Zealand's Ministry of Civil Defence and Emergency Management said it and GNS Science were assessing if it had generated a tsunami that could affect New Zealand.

Authorities in Kodiak, Alaska, are telling residents to move to higher ground after a strong earthquake struck nearby, prompting tsunami warning for a large swath of coastal Alaska and Canada's British Columbia while the remainder of the US West Coast was under a watch.

A dispatcher at the Kodiak police department answered a call from The Associated Press by saying: "If this about the tsunami, you need to get to higher ground immediately."

Warnings from the National Weather Service sent to cellphones in Alaska warned: "Emergency Alert. Tsunami danger on the coast. Go to high ground or move inland."

Kodiak officials warned residents to evacuate if they lived in low-lying areas.

People reported on social media that the quake was felt hundreds of miles away, in Anchorage

According to the Tsunami Warning alert on Google, all coastal areas of British Columbia and Alaska from The Wash./BC Border to Attu, Alaska need to evacuate to higher ground.
