Oklahoma starts the flurry of mid-four earthquakes
M4.3. I was thinking they would just jump to high 4's, but this place is slow.... As per the program, we'll have a flurry of 4's, followed by a resting phase of high 3's. They bumped this one up, so it might be mostly normal (tension).
Blah, this is out in the boonies, so they don't have a focal mechanism. We'll get good ones for the ones close to the city. This one follows the opening of Mechanism #2 and that thrust earthquake a while ago. We are really ready for thrusts on #1.
Update: Wow, first a 4.2, and now knocked down to a 3.9, this has enjoyed a roller coaster. Both earthquakes have had the highest discount ever.
Update2: The focal mechanism is normal, total tension, on a weird plane.
Update3: No flurry, I was basing that on a real 4.3. If we get a mid 4 thrust on the main plane, then it's a flurry.
