Just felt an earthquake.   Small - shook the building for a couple of seconds and then dissapated.   A couple of the folks in the office thought it was just someone dropping a box or something.

This is the second earthquake I've felt and had an opportunity to blog about.  There's not much to say when describing it - it felt like a strong wind shaking the building.   What distinguished it for me was that instead of just a single "rock" of the building, it swayed back and forth for a few seconds (perhaps 3-4?).

Perhaps 3-4 years before starting the blog, I felt an much stronger quake back in my Seattle days.  That one *clearly* rocked the building and was pretty unambiguously an earthquake although with zero damage.
