A tsunami warning has been issued for Alaska after a 7.4-magnitude earthquake hit in the Pacific Ocean, 172 kilometres east of Atka in Alaska, at a depth of about 40km, the US Geological Survey (USGS) said.
The Bureau of Meteorology (BOM) says there is no tsunami threat for Australia at this stage
The quake on the Fox Islands - 163 kilometres east of the tiny fishing port of Atka - stuck at 6:09pm local time, the USGS said in a statement.
There were no immediate reports of damage or injuries.
The West Coast and Alaska Tsunami Warning Centre said a tsunami warning was now in effect for the coastal areas of Alaska.
A magnitude 7.4 earthquake rocked the Aleutian Islands of Alaska Thursday evening, prompting officials to issue a tsunami warning for parts of the coast of Alaska.
According to the USGS, the quake was centered 39 miles southwest of Amukta Island, Alaska, at a depth of 29.1 miles. It struck at 6:09 p.m. local (Aleutian) time, or 11:09 p.m. Eastern time.
A tsunami warning was issued a short time thereafter for a portion of the Alaskan coast extending from Unimak Pass to Amchitka Pass. The first waves are projected to reach Adak, Alaska, at around 8:12 p.m. local (Alaska Daylight) time, or 12:12 a.m. Eastern time.
Adak is a city with a population of just over 300 located in the western Aleutians.
There have been no immediate reports of any damage from the earthquake or of any tsunamis at this time.
Stay tuned for updates on this earthquake and potential tsunami.
A preliminary magnitude 7.4 earthquake has hit the Aleutian and Fox Islands off the coast of Alaska.
The Pacific Tsunami Warning Center says there's no destructive widespread tsunami expected, but earthquakes of this size can sometimes generate local tsunamis along coasts 100 kilometers from the quake.
The National Weather Service says a tsunami warning is in effect for the coastal areas of Alaska from Unimak Pass, 80 miles NE of Dutch Harbor, to Amchitka Pass, 125 miles West of Adak.
This area is located in the earthquake "ring of fire", in the Bering Sea.
