Hi Lowell. In regards to the Utah quake the amount of stress relived (if any was relived at all) was minuscule. Besides it could have gone the other way, but even that is doubtful. Besides there is always the possibility that the pressure wave motion (provided there is such a thing) hypothesis may be responsible for the triggering of some of the quakes. I think I will the Utah forecast as is. Take Care…Don in creepy town.
