In December of 1872, an earthquake shook the Pacific Northwest so hard that a Seattle resident described watching near-tidal waves roil Lake Union.

And it wasn’t just Seattle; the quake shook from Eugene, Oregon to Canada. It triggered a landslide near Wenatchee that briefly dammed the Columbia River.

A 4.2 earthquake gave a shake to Lewis and Thurston counties just before 8 am this morning. The US Geological Survey reports the small temblor was centered between the town of Morton and Mossyrock.  No injuries or damages have been reported.
