A magnitude 5.8 earthquake has struck off the coast of Alaska, close to the city of Anchorage, rattling buildings and knocking items from shelves, but no serious damage or injuries were reported.
The tremor, initially reported as a magnitude 5.7, struck at 4.42pm (2.42pm NZT) 41 km west of Anchorage, the US Geological Survey said.
The quake, relatively shallow at a depth of 53 km, was widely felt in Anchorage, according to Guy Urban, a geophysicist for the West Coast and Alaska Tsunami Warning Center 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.
