"We are looking for M6+ near the Bay Area of San Francisco...by the end of next week.
Idaho Yellowstone area due for M4+ activity , Southern Colorado New Mexico border could go as high at M4.9 to M5.0. Dallas Texas ( to South Texas) should keep watch for the same size activity, upper M4 to low M5 range.
East Coast Virginia should see the same sized activity which strikes Colorado, therefore keep watch for up to M4.9 to M5.0.
