The U.S. National Oceanic and Atmospheric Administration (NOAA) issued a tsunami warning.
It initially spoke of a magnitude of 8.1, then also corrected to 8.2, but located the quake just under 121 kilometres South-East of the town of Chignik, also located on the peninsula.
There were initially no indications of casualties or significant damage.
