USGS just reported a 2.6 magnitude shake in Dallas. That's pretty small. You wouldn't feel something that small as far away as Plano.
I am a native Southern Californian and I do know that I have felt some significant jolts from small quakes that happen to be right under us! I remember feeling a what I thought was a larger quake, only to find out that is was only a 2.0 but directly under our house!
