Hello John,

Been a while. Does Omari law apply to 3 near equal quakes in energy, or something that can be considered a mainshock? As such, none of the 3 Mexicali quakes can be considered a mainshock, or is that law based on the first to hit of 3 equal magnitude quakes? I think the first at re-established 5.4 Mw was the largest. The following quakes were 5.1 or so. The falloff math does not seem right for this sequence as in energy. Timing seems right though. The question is energy vs timing.

Appreciated
Glen
