There was a big flurry of earthquakes yesterday. They are tracking the northern fault, with compression earthquakes at the end, just like Cushing. For a while the system appeared to be resting.
Add: Cushing just had one of its high intensity shallow thrusts. m3.6
Add2: Watch this little video. Look at the crappy state of the oil tanks. And those berms are a joke. I had to fix one once. They are designed by people who can't do math, and have a special valve that is supposed to let out the water, and is made of the rustingnest iron. :)
