"Earthquake Strikes Anchorage with Magnitude 4.2"

A magnitude 4.2 earthquake occurred 3 miles north of Anchorage, Alaska, with a depth of 24.6 miles. The event was felt in the greater Anchorage area and has been reviewed by a seismologist. Earthquakes in Southcentral Alaska are caused by various tectonic features, including the subduction of the Pacific Plate beneath the North American Plate, intermediate-depth seismicity in the Wadati-Benioff Zone, and crustal seismicity related to faults and folds in the Cook Inlet basin and the Castle Mountain Fault.
