Something just happened. I’d say a huge semi-truck or two just drove by too fast and went through the crazy potholes (or something) but that’s not really possible where I am let alone it would have had to had been a 180 wheeled truck since it lasted a bit. It really shook the place for at least 4-5 seconds (it seemed much longer but I’m guessing it wasn’t) with a short ones a few seconds later about 22 or 23 minutes after midnight. Afterwards, it sounded like a few doors opened up at the hotel but no chatter of what might have happened. I don’t know how common earthquakes are here. I know I’ve never felt anything like it!

I’ve been looking on-line and finally found some data! It was a 4.3 Magnitude earthquake!!!! Not sure how big that is, but I’m from Michigan so…

The event id for this is “us2008wnan” as it’s official designation (I guess). This is the closest seismogram I could find from a drum recorder (are they still actually drums?) which happens to be the Volcano at Rincon de la Vieja, you can clearly see in the second block of 15 minutes after midnight the needle went a little crazy. Here’s some info on reading the seismograms.

Looking at the attached right-hand image (the “A” is the estimated center), I’m guessing it centered about 25-30 miles from here (Tamarindo). The smaller left-hand image has some time/date info with location info (and no other earthquake boxes for the last week in Costa Rica).

This was at 10.490°N, 85.851°W, a 4.3 magnitude and 39.7 miles (63.9 km) deep. Could this have been picked up as far os New Mexico or Oregon? Or were those coincidental marks on their graphs? Finding this I’m going to say “yes” (I found this in the morning).

I’ll keep adding data as I find it! It’s been two hours I’ve been collecting info, I’m off to bed, gotta get up in the morning to catch a flight.
