You might have heard by now about the 6.9-magnitude earthquake off the far-northern California coast a little more than an hour ago. It could be seen on at least two official seismographs in West Seattle that are part of the Pacific Northwest Seismic Network – above, the online display from the detector at the Alki stormwater-treatment plant; below, the one at Holy Rosary (which is a bit busier):

So far, no word of notable damage from the 10:18 pm quake 50 miles west of Eureka, California, according to former WSB contributing photojournalist Nick Adams, who lives and works there now. For us, yet another wakeup call – do you have your go bag? Know where your communication hub is? Browse westseattlebeprepared.org next time you can spare a few minutes.

P.S. Thanks to Skies Over West Seattle correspondent Alice Enevoldsen for the tip about the local seismographs,
