A magnitude 3.9 earthquake shook Southcentral Alaska near Hope on Friday night

A magnitude 3.9 earthquake shook Southcentral Alaska late Friday night, centered near the small Kenai Peninsula community of Hope, the U.S. Geological Survey and the Alaska Earthquake Center reported. It struck at 11:42 p.m., just outside Hope and about 23 miles south of Anchorage across Turnagain Arm, at a depth of roughly 19 miles.

Plenty of people felt it: more than 800 filed "Did You Feel It?" reports with the USGS in the first 45 minutes, describing the kind of light indoor shaking that comes without damage. No tsunami advisory was issued, and no foreshocks or aftershocks were recorded near the epicenter in the hours around it.
