New Madrid M2.6 earthquake
Unlike Alaska, you can joke all you want about this cluster of earthquakes, and not worry about being hoisted. These are all the earthquakes over the last 6 months, and they form the exact pattern over the previous umpteen years since the Big Ones.
I just picked up on this earthquake, since I was hoping for a break in the pattern a while ago, namely extending the zone to Dyersburg. And it looked like, if Arkansas continued massive injection, that we could get a New-New Madrid. Alas, most of the immediately deadly injection has stopped, and we only have the long term effects of overflowing a thin Cambrian sandstone layer. Who knows when that will do something?
