The National Weather Service sends along a note reminding the Outpost that their big drill is not today, but in March — so no sirens in Old Town. We are told, however, that those near the King Salmon blast zone were treated to PG&E’s long, lonesome whistle.

siren test at power plant… eerie sound… and done

All hell is going to break loose in Humboldt County at precisely 10:16 a.m. Tsunami sirens will (hopefully) blare. Coworkers will dive under their desks.

It’s the Great American Shakeout, people — a time to remember that the earth beneath our feet is forever ready to break loose and attempt to murder us all. How to cope with this existential state of affairs? Don’t freak out — shake out! Be prepared! And that’s what schools, tribes, local government and a host of other Humboldt County organizations and individuals will be doing shortly.

Shake it out, Humboldt! Get ready for this! Here’s how!
