A 4.6 magnitude earthquake overnight rattled the Three Lakes area of Washington state, the U.S. Geological Survey reported.
The initial temblor, recorded at 2:51 a.m. Friday at a depth of nearly 14 miles below the surface, was followed minutes later by a 3.5 magnitude aftershock near the city of Monroe, some 30 miles northeast of Seattle.
A USGS map showed light shaking felt in the Seattle area, down to Olympia and as far north as Vancouver, Canada.
