I’m not buying the big red blob that runs down the entire East Coast to Florida. It is a passive margin and one would expect tension instead of compression (i.e. normal faults instead of reverse faults.) Glacial rebound all the way down to Florida? Ha.
There was a small quake in the gulf of Mexico awhile back. My mom felt it in Ocala.
I agree, the color bar on that grid needs to be inverted, Cali should be red, east coast green.
