A magnitude 5.8 earthquake struck off the coast of Alaska. close to the city of Anchorage, rattling buildings and knocking bric-a-brac from shelves.
The tremor, initially reported as a magnitude 5.7, struck at 4.42pm (local time), 41km west of Anchorage, the U.S. Geological Survey said.
The quake, relatively shallow at a depth of 53km, was widely felt in Anchorage, according to Guy Urban, a geophysicist for the West Coast and Alaska Tsunami Warning Centre in Palmer, Alaska.
"Some people in Anchorage said some things fell off the shelves," he told Reuters, adding that the centre was unaware of any severe property damage or anyone being hurt.
Quakes of similar strength are fairly common in Alaska, one of the most seismically active parts of the United States.
