A series of earthquakes shook Southern Alaska early this morning.

The first quake struck at 3:23 a.m. local time (4:23 a.m. B.C. time) today (November 7).

The U.S. Geological Survey measured it as a 5.1-magnitude seismic event while the Alaska Earthquake Center reported it as 5.0-magnitude.

The epicentre, as a depth of 35 kilometres (22 miles), was located four kilometres (three miles) east of Big Lake, Alaska; 28 kilometres (18 miles) northwest of Eagle River, Alaska; and 35 kilometres (21 miles) north of Anchorage, Alaska.

A 4.0-magnitude quake followed shortly thereafter at 3:27 a.m. (4:27 a.m. B.C. time), at the same depth.

The epicentre for this one was 14 kilometres (nine miles) northwest of Big Lake, 44 kilometres (27 miles) northwest of Eagle River, and 44 kilometres (28 miles) northwest of Anchorage.

A third quake occurred at 6:03 a.m. (7:03 a.m. B.C. time), which the U.S. Geological Survey measured as 4.6-magnitude.

This epicentre, at a depth of 34 kilometres (21 miles), was located four kilometres (three miles) northeast of Big Lake, 29 kilometres (18 miles) northwest of Eagle River, and 35 kilometres (22 miles) north of Anchorage.

Several other smaller aftershocks were recorded but were too small to be felt.

All three earthquakes were reported as felt in the Anchorage area.

Yesterday (November 6) south of British Columbia, a 4.0-magnitude quake struck the area near Boise, Idaho. 

The U.S. Tsunami Warning System stated that there wasn’t a tsunami risk from these quakes, and that there wasn’t any threat to the Alaska or British Columbian coastlines.
