Did You Feel It?

I don't really focus this blog on current events, but it's hard to focus when the ground is shaking!

There was a moderately-strong earthquake yesterday, centered about 100 miles east of us. Here's a view of the region, showing the locations of the 73,786 people who have contacted the US Geological Service about the quake:

The quake was about 7.2 in intensity, and originated near the star on the map. It's a sparsely populated area in northern Mexico. Geologists are still working to determine the exact location.
