Oklahoma M4.2 earthquake - into the Enid Breach
Into the breach. This earthquake was strongly felt by experienced people, so it may be a thrust.
It has the pattern that I would expect for a thrust - intense and a small area. All in all, the mechanism is growing nicely. I still have no idea as to why the Enid Breach exists, I think there may be two megathrusts that have run together. The oil companies know, since they have the records, the rest of us have to guess.
Update: Still no solution, but this was followed by an M3.5 on the lower thrust.
And the intensity map shows a thrust.
We won't get a solution for this one, too small. But the reports should be of 'explosions' if I can find any. The big thrusts may be finally coming in. We must wait for the fault plane solutions.
Update2: On the other hand the M3.8 near Prague had a strike-slip pattern.
But it did some windows, so it is probably shallow. This is getting quite close to M5.6 and may be in a stress ring.
No discounts or solutions today, it's Sunday.
On Monday, still no solution.
