Couldn't have been too big, since it didn't show up on the USGS site (where the map above is from), but the Costa Rican monitor, OVISICORI, appears to be overloaded on their website as I can't get in there. If it doesn't show up on USGS then it was under 2.5 magnitude, which means the epicenter was pretty close to my location.
I don't know if it's just me, but it seems like the last year we have had far fewer quakes than in previous years. The long gap between them makes me nervous that we're going to get a big one, which is irrational, since there is no such correlation between frequency and strength of quakes. Still, you sometimes feel that in the 3rd most tectonically-active place in the world that you are tempting fate!
