This is great research Lowell - Now we keep our eyes open and see what follows this one.

The other thing a little surprising is that there are so many large quakes in that area - It helps to see them listed out like that.

This one was pretty deep but looking at the Historical sesmicity map it looks like most are shallow quakes - If you add depth into the analysis - or say those deeper than 150km vs shallower quakes does it have any more effect in the other areas that have quakes? Like - is Northern cal only affected with the deep ones or ?
