JACKSON, Wyo. -- A magnitude 4.6 earthquake has hit northwest Wyoming, apparently triggering a landslide on a hiking trail, but no injuries have been reported.

The U.S. Geological Survey says the quake hit at about 11:45 a.m. Sunday.

Bridger-Teton National Forest spokeswoman Mary Cernicek says rangers are investigating reports that a landslide covered about a quarter-mile of a trail in the national forest about 20 miles northeast of Jackson.

Cernicek says some hikers may have been further up the trail, beyond the landslide, but she didn't know how many. She says no one is believed to have been in the slide.

Cernicek says the slide wouldn't prevent any hikers from getting out. She says a forest ranger is checking to see if anyone is on the trail.
