The USGS has reported that a pair of large earthquakes shook South-central Alaska Sunday evening, July 5, 2015.
According to the Alaska Dispatch News [1]:
The first earthquake hit at 4:49 p.m., had a magnitude of 4.9, and was centered 38 kilometers southwest of Talkeetna, according to the USGS [2]. A second earthquake less than a minute later shook nearly the same location and had a magnitude of 5.1.

Earlier Sunday, an earthquake struck 20 kilometers northwest of the Arctic community of Kaktovik, in the Arctic Ocean off the North Slope coastline. That earthquake, which occurred at 11:26 a.m., registered as magnitude-4.6, according to USGS.
