Magnitude 5.8 Earthquake Strikes Alaska
WILLOW, Alaska (CBS SF) — The U.S. Geological Survey says a strong earthquake struck in Alaska, but no tsunami was expected.
The 6.2-magnitude quake struck at 2:32 p.m. with its epicenter about 64 miles west of Willow, Alaska. It was later downgraded to a magnitude 5.8 quake by the USGS.
The quake struck at a depth of 64 miles.
Deeper quakes are less noticeable while a shallow quake--in the 0 to 40 mile depth range--can feel much stronger than their actual reported magnitude. Quakes just below the earth's surface, in the 0 to 10 miles range, can cause even more damage at lower magnitudes.
No damage or injuries were immediately reported.
