A 2.8 magnitude earthquake occurred at 4.04am local time, with its epicentre 45km north-east or Old Iliamna. It was followed by a second 2.5 magnitude quake at 5.19am, with its epicentre 35km south-west of Kodiak Station.
It comes after a magnitude 7.9 earthquake struck in the Gulf of Alaska shortly after midnight local time on Thursday.
The huge quake sent coastal residents rushing to evacuation centres to seek shelter from a possible tsunami, with warnings extended as far south as San Francisco, California.
Witnesses reported the quake could be felt for around a minute.
There were no immediate reports of injuries from the earthquake, however communities in Alaska will gave to cough up to fix some minor damage. Large cracks appeared in the walls of Kodiak City Fire Hall, while a small oil spill was reported at a refinery.
Tsunami warnings were lifted early on Thursday morning.
Large earthquakes are not uncommon in Alaska, which is seismically active and is likely to be struck buy several more earthquakes this year with 11 months still to go.
Meanwhile California has been struck by 10 earthquakes in a 24-hour period, with three earthquakes measuring more than magnitude four.
The largest earthquake, which look place at 8.39am local time on January 25, measured 5.8 magnitude, while a smaller 5.1 shock followed less than an hour later, at 9.24am.
Fortunately no serious damage was reported and the National Tsunami Warning Centre said there was no risk of tsunamis in California as a result of the quakes.
However the huge surge in seismic activity in the last 24 hours has sparked fears of a ‘Big One’, an imminent earthquake of more than 8 magnitude that could have the power to decimate the US west coast.
From Indonesia, to Japan, to Hawaii and Alaska, the entire region sits in what is known as the Pacific Ring of Fire – an extremely volatile chain of active volcanoes, tectonic plates and earthquake zones. Most of the world’s earthquakes happen in this region.
The number of quakes in close proximity this week has triggered fears the Big One could be coming soon.
The major quake is expected to happen along the San Andreas fault, and could cripple the state of California.
The name stems from a 1990 made-for-TV movie that depicts a huge earthquake that destroys all of Los Angeles.
