An earthquake considered of "great" magnitude on the Richter scale has just struck south of the Alaska Peninsula.
The quake hit at 10:15 p.m. Anchorage time (11:15 p.m. Vancouver time) on July 29.
Initially registering as 7.2-magnitude based on preliminary measurements, the U.S. Geological Survey later reassessed it as a 8.2-magnitude seismic event.
At a depth of 46 kilometres (29 miles), the epicentre was positioned 91 kilometres (57 miles) southeast of Perryville, Alaska; 792 kilometres (491 miles) southwest of Anchorage, Alaska; and 1458 kilometres (904 miles) southwest of Juneau, Alaska.
Mere minutes later, it was followed by a 6.1-magnitude quake at a depth of 27 kilometres (17 miles), then a 6.2-magnitude quake at a depth of 42 kilometres (26 miles) in the same area.
A number of other tremors have also followed, including a 5.6-magnitude temblor.
The U.S. Tsunami Warning Centre has issued a tsunami warning for South Alaska, the Alaska Peninsula, and the Aleutian Islands.
Anyone in a tsunami warning area is recommended to leave any water, shoreline, or beach areas, and to evacuate to higher ground or move inland.
The threat of a tsunami to other U.S. and Canadian coastlines is still under evaluation. Emergency Info B.C. stated that B.C.–specific information is still to come.
