Hi Lowell - I find this confusing:
There is a strong relationship between New Britain events and
succeeding earthquake in southern California especially in the
area of Anza to the Salton Sea. This is probably because wave
fronts from New Britain arrive approximately parallel to the
San Andreas in this region, promoting larger events.

Didn't the Anza quake this morning occur before the New Britain quake?

So you are also saying there's a possibility for another sizable quake to occur in the area?
