Magnitude 6.4 earthquake strikes Alaska
The quake does not appear to have caused any damages, nor has it raised the risk of a tsunami.
A Magnitude 6.4 earthquake has struck Alaska at 8:54 a.m. local time (AKST).
It occurred on the Denali fault line, which has been active for the past 48 hours. During this time, twelve other earthquakes have occurred, with the Magnitude 6.4 quake being the strongest so far.
According to the U.S. Geological Survey, (USGS), the quake does not appear to have affected any nearby population centres.
It occurred 224 km east-southeast of Attu Station, Alaska, at a depth of around 10 kilometres.
There is no tsunami threat, and USGS says it is unlikely this event caused any significant land or structural damages.
There is, however, potential for aftershocks.
The Denali Fault is a major fault in western North America that extends from northwestern British Columbia to central Alaska.
It is around 2,011 km long.
Alaska is one of the most siesmically active regions in the United States, experiencing about 1,000 earthquakes each month -- although most are small.
According to the Government of Alaska, 11 per cent of the world's total recorded earthquakes occur in the state.
