I woke up to a shaking house at 3 a.m. this morning.
The shaking went on for only a few seconds, but I was sure it was an earthquake. It turned out there was a magnitude 3.5 quake, and the one I experienced must have been the 4.6 quake that followed just two minutes later.
The epicenter of the quake is about 26 miles from my house. No real damage or injuries in the Puget Sound area or from elsewhere, were reported.
P.S. The Nisqually earthquake of 2001 near Olympia was several orders of magnitude stronger, at 6.8. It damaged the Alaskan Way Viaduct, the dome of the State Capitol building in Olympia, and Starbucks headquarters in Seattle.
