Oklahoma earthquakes - incredible density of events
From Friday, I've never seen so many events, from about mid-3 and down. This type of sequence always culminates in some large ones, and then it settles for a while. There are some indications that the sequence is gaining some depth which is required for larger quakes. Anyway, no predictions, we'll have to see.
Update: Just in, the St. Paddy's M4.2. Another 'invisible' earthquake, this one looks strike-slip. Will probably be discounted.
