      A strong undersea earthquake struck south of the Alaskan Peninsula during the night.

      It hit at 3:57 a.m., Anchorage time (4:57 a.m., Vancouver time) today (August 14).

      The U.S. Geological Survey initially measured it as a 6.4-magnitude quake before reassessing it as 6.9-magnitude, which the Alaska Earthquake Centre also listed it as.

      It struck at a depth of 33 kilometres (21 miles).

      The epicentre was located 117 kilometres (73 miles) southeast of Perryville, Alaska; 804 kilometres (499 miles) southwest of Anchorage, Alaska; and 1454 kilometres (901 miles) southwest of Juneau, Alaska.

      It has since been followed by four other temblors, ranging from 3.6- to 4.2-magnitude.

      Emergency Info B.C. stated at 5:18 a.m. that there wasn’t any tsunami threat to B.C., and the U.S. Tsunami Warning System, which listed it as a 7.0-magnitude quake, also stated that there wasn’t a tsunami threat to Alaska or the North American West Coast.

      This seismic event follows a powerful undersea quake on July 29 that registered as 8.2-magnitude in the same area. 

      A tsunami warning had been issued for Alaskan coastlines for that quake but was later called off.

      Meanwhile, a 4.3-magnitude quake occurred northwest of Anchorage on August 11.
