6.1 just happened within the last hour.edit on 3-4-2014 by phoenixlights321 because: (no reason given)
Somebody in the know, answer this:
With two major quake in the last 48 hours in this area (Peru, then Chile), just how connected, geologically, is this zone to the West Coast of the US? Is it all part of the Pacific Rim Ring of Fire?
My understanding is that it is all somewhat interconnected. If that's the case, I can't help but wonder what this may mean for California.
Just tossing this out here for some established guidelines to guage aftershocks...
Aftershock size and frequency with time
Aftershocks rates and magnitudes follow several well-established empirical laws.
The rate of aftershocks with time follows Omori's law. Omori's law, or more correctly the modified Omori's law, is an empirical relation for the temporal decay of aftershock rates.
The other main law describing aftershocks is known as Båth's Law and this states that the difference in magnitude between a main shock and its largest aftershock is approximately constant, independent of the main shock magnitude, typically 1.1–1.2 on the Moment magnitude scale.
Main article: Gutenberg–Richter law
Aftershock sequences also typically follow the Gutenberg–Richter law of size scaling, which refers to the relationship between the magnitude and total number of earthquakes in a region in a given time period.

The last time Chile rocked like this the Japan quake was right behind it.
