There was an earthquake just north of Puerto Rico twenty minutes ago. It’s likely any damage will be minimal with no tsunami. Just like weather and other sci/tech pursuits, I follow quakes.
Our government, the USGS specifically, does an excellent job analyzing the data and quickly posting the results. It’s mostly an automated process, so even on a Sunday evening there’s no wait.
On the left is their front page link to the Puerto Rico quake. There are two entries because the original report was revised.
Each quake gets its own series of webpages. The first page contains a map pinpointing where the quake happened, plus an academic description of local seismology. This one got, “Seismotectonics of the Caribbean Region and Vicinity.” Riveting prose.
More useful on an immediate basis are the DFYI and PAGER pages.
DFYI (Did You Feel It) is an Internet derived ‘shake report.’ Regular folks try to quantify their experience. It’s very insightful when plotted on a map.
Most felt the shaking was light.
PAGER estimates the damage based on all the available data. Computer modeling at work. An educated guess. Tonight, it’s overdone. San Juan felt light shaking. PAGER says strong.
PAGER also predicts up to 10 deaths. Hopefully that’s overdone too.
Geoff, I’m waiting for the day you wake up in the middle of the night and your house is shaking. You can’t figure out where you are or where to go.
