Tiny Earthquake Hits Chicago

A tiny M4.3 rattles Chicago. As with all these interior earthquakes, they are felt out of all proportion to actual damage. I think they are just bitchy because of all the snow! In the historical seismicity, it looks like there have been very few earthquakes, but I suspect this area is very poorly monitored. An M4.3 usually has some reason for its existence!

Isostatic rebound???

It's most likely my standard water hypothesis, but the area is unmonitored.

Can you point me to your water hypothesis. Does this hold for the seismicity in western Lake Ontario?

Again, look up some of my articles on fault mechanics in Geofish Clarified on the left margin.
