Tsunami warnings were lifted for Alaska and the rest of Pacific after a huge earthquake of 8.2 magnitude struck the seismically active US state in the late hours on Wednesday.

In Alaska, small tsunami waves measuring under a foot above tide level were observed in Sand Point, Old Harbor, King Cove, Kodiak, Unalaska and Alitak Bay, according to the US National Tsunami Warning Center (NTWC).

There were no immediate reports of injuries or damage to property. Several Alaskan coastal communities were evacuated following the quake. Among them was Seward on the Kenai Peninsula, south of Anchorage, where sirens blared and residents were told to move to higher ground.
