A magnitude-4.3 earthquake rumbled under Washington state's Cascade Range, but no damage has been reported.

The Pacific Northwest Seismic Network says the quake struck at 1:04 a.m. Wednesday and was centered about 20 miles north of Ellensburg and 10 miles northeast of Cle Elum in central Washington.

Dispatchers for the Kittitas County sheriff's office say they received calls from people who felt the temblor but no reports of injuries or damage.

The U.S. Geological Survey website shows more than 150 reports of the quake being felt.
