According to the US Geological Survey, the 7.5 Richter earthquake occurred at a depth of nearly 40km, about 90km south of Sand Point, Alaska, on October 19.
According to RT, the US National Weather Service issued a Tsunami warning to residents in South Alaska and the Alaska Peninsula immediately after the earthquake, but said the risk level was still being assessed for other coasts of the US and Canada. No injuries or damage were reported.
People in the affected areas have been asked to evacuate inland or to higher ground, away from the coast, as well as seaports, cruise ships and bays.
A series of aftershocks were recorded shortly after the first earthquake, in which the two largest were recorded at 5.8 and 5.2 degrees richter, both south of Sand Point - a small city on the Alaska Peninsula with a population of just over 1,000 people - about 100 km.
On the other side of the Gulf of Alaska, authorities in British Columbia, Canada, also said they are assessing the risk of a Tsunami, asking residents to be on duty to update information if they are asked to evacuate.
Located along the northerntermtermterm of the Pacific "Ring of Fire", Alaska is one of the most seismically prone states in the US, with an average of about 40,000 earthquakes per year and more earthquakes than any of the other 49 states combined.
The strongest earthquake ever recorded in Alaska - and truly the entire North America - occurred in 1964, reaching 9.2 degrees Richter, causing landslides and sunslides that killed 131 people, including some as far away as California and Oregon.
