Oklahoma M4.3 earthquake party

Yep, another one.  Good thing it is in the middle of nowhere.  Doesn't mean anything.  This will probably get discounted to M4



Update:  Two identical earthquakes at the same spot are called couplets and are diagnostic of injection.  This one was felt more, perhaps because the first one softened things up.


Note the effect of swamps on the large scatter.

Update2:  No reduction.  A real M4.3
