Nutshell: Dutch confirms to look for movement both above and below the Mexico quake. Said to expect swarms along the plate boundaries, which are put into motion from such a large quake (he noted Utah, which is on the plate edge, occurred immediately after Mexico). Normally the energy would not transfer north up into U.S. but it does when there is a quake of this size.

Watch areas on high alert for next 3 days for a 6.0-6.9 EQ:

Central cali around NV border, down to L.A., Long Valley, and into Baja Mexico.

South America, including Ecuador, Colombia and Peru

Caribbean islands: Due to natural transfer of energy both south and due east from where Mexico quake occurred.

If no quakes of this size occur within 3 days he would change his prediction from a warning to a watch, and would expect a slightly smaller magnitude for these same areas.
