A minor earthquake shook an area southwest of Mount Rainier yesterday, the University of Washington's Pacific Northwest Seismograph Network reported.
There were no immediate reports of any damage or injuries.
A preliminary report by UW seismologists said the 3.7-magnitude quake happened at 2:48 p.m. and was centered 27 miles south-southwest of Mount Rainier, about a quarter-mile below the Earth's surface.
The quake was felt as far away as the Portland suburb of Tigard. A spokesman from the Pacific Northwest Seismograph Network said the quake was probably felt so far away because of its shallow depth.
