Earthquakes

When I lived in the Bay Area, I noticed that 4.x quakes only tended to
shake the room ever-so-slightly. You could only really tell if they
happened, if you happened to see liquid in a glass moving.

We had a 6.2 last year in Costa Rica... We immediately regretted where
we
had placed our racks and are almost finished a project to move them to a
concrete floor (rather than that compressed cardboard stuff). Lost a lot
of
hard drives that day! We regularly have quakes between the 4-5 region
here.
By regularly, i mean a minimum of 5 times a year in different parts of
the
country.

Interesting, the epicenter was only a few km (about 30) from the capital
city and no communications were knocked out (except within a 6 km radius
of
the epicenter which was affected more by mud slides knocking things
over.
Here's what it looked like... http://www.youtube.com/watch?v=F8udXyyqUiw
