A 6.2 earthquake shook parts of southern Alaska on Thursday morning, but its depth suggested the impact on the small towns nearby could be modest.
The quake, estimated at a 6.2 magnitude, was centered 60 miles west northwest of Willow, Alaska, and 81 miles northwest of Anchorage.
The quake struck at a depth of 63 miles. In contrast, the magnitude 6 earthquake near Napa, Calif. was at a depth of 7 miles.
Alaska is the most seismically active U.S. state. Many Alaskans fear a quake along the lines of the 1964 "Good Friday" earthquake, which caused 139 deaths, mostly from a related tsunami.
The town of Willow, with a population of 2,300 people, might be familiar to some outside Alaska because it's reportedly the source of name of Willow Palin, daughter of former candidate for vice president Sarah Palin.
