Given two facts of life:
1. The character of Charlie Epps is becoming something of a "hero" of mine and
2. I'm good at being obnoxious if nothing else
I decided to check-up on my geography recollection, pin-point the quake, and give us all a
sense of scale.
The image below overlays the US (rotated) and China. The scale is accurate on both.
The image is position such that the Mexicali Quake overlays the China Quake.
Los Angeles is marked (not picking on you, JenJen, not by a long-shot, but it's a familiar marking.) Leaford's location is also marked, although approximate (I just figured somewhere within ~20mi of Shenzhen, where the vast majority of manufacturing takes place)
We can see by comparison that Leaford is in Louisiana by scale. (!) So we should be asking if people in Louisiana and Witchita felt the Mexicali quakes, by comparison.
