New Update: Feb 4

The Jan 9th quake caused our Muni building to be red tagged, forcing us to move to another building in downtown Eureka. This morning at our meeting, I mentioned being grateful that we didn't have more quakes lately. Half an hour later, we had another earthquake! A small one offshore, 5.9 on Richter scale although it felt like a 4.0 locally. Now we have a bad windstorm blowing outside, the big trees blown sideways... what a day!

- Jan 9

We had a quake about 5pm, more roller than rocker, either a 6 or 6.5, I had estimated a 5.5 - 6.0 on Richter scale. Haven't heard of any tsunamis.

Rockers are worst, when 2 waves collide at an angle, very jolting.
Rollers are single directional, so unless very large they just move like a normal surf wave.

I happened to be outside near the garden, so no problem except possible electric wires breaking (they were whipsnapping a lot). No external cracks in the Muni bldg [except a crack in the ramp], a window fell out, lots of plaster fell from the ceiling, books and art fell, etc. no injuries here. Lights back on by 11pm. [Part of the building shifted up a bit.]

After working so hard on the new wood floor and painting the galleries... alas.
