Just ten minutes ago we had a small earthquake here. Not that unusual, except this one was a "double", which was a first for me. The first shock built slowly, then there was a few seconds gap, followed by a stronger shock. The upper floor, where I blog, felt like it was reverberating for quite some time thereafter.
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!

Well, USGS picked up the quake after all (real-time my ass! LOL). It was a 4.6 magnitude and actually quite a ways away, NW of San José, probably about 100 miles as the toucan flies.

Earthquakes are unsettling because we just assume the ground to be a stable thing in our lives, right?
ReplyDeleteGlad to hear it wasn't too bad!
I have found that they are so frequent that I 1) am very sensitive to the first vibrations, and 2) am pretty complacent about them. I don't duck for cover like I know I should.
ReplyDeleteI have never experienced an earthquake and I imagine it must be really scary, the closest I have been is the room shaking (very lightly) for about 5 seconds, but it was so light we didn't even know it was an earthquake! It's amazing how strong mother nature is!!!!
ReplyDeletesame as mine, Indonesia is in the line of volcano....earthquake and volcanic eruption is the major threat for us.

We were out for breakfast in Atenas (which must be near the epicenter) and actually didn't feel a thing. But Layne and I have endured some BIG ones in the San Francisco area so we too are a bit complacent about them. Like you, I nonsensically welcome the small ones as avoiding the big ones.
ReplyDeleteI used to live in LA and once slept through a 5.3 Don't worry about it. You have as much chance as a meteorite hitting you on the head.
ReplyDeleteNice blog.
