A 7.0 earthquake shakes up Alaska, no tsunami threat
On November 30, 2018 at 9:29 a.m. Pacific Standard Time (or 15:29 UTC), there was a moment magnitude scale (M) 7.0 earthquake near Anchorage, Alaska, occurring as the result of normal faulting at a depth of about 40 km. This was followed by a smaller M 3.4 earthquake at 10:15 a.m. PST.
There is an expectation of aftershocks.
A tsunami warning was first issued for the surrounding coastal areas near Anchorage Alaska but has since been lifted. No broader tsunami warning, advisory, watch, or threat expected.
No deaths or injuries have been reported, although there is infrastructure damage.
Earthquakes are common in this region. Over the past century, 14 other earthquakes with a magnitude of 6 or greater have occurred within 150 km of the November 30, 2018 event. Two of these – a M 6.6 earthquake in July 1983 and a M 6.4 event in September 1983 – were at a similarly shallow depth and caused damage in the region of Valdez. The M 9.2 great Alaska earthquake of March 1964, was an interface thrust faulting earthquake that ruptured over several hundred kilometers between Anchorage and the Alaska-Aleutians trench, and to the southwest.
