Could we Say that a Large earthqauke on one side of the glode can trigger another earthquake on the other side? Not even on the same plate, and even more so if it was?
I think the experts say no, is that correct? anyway just thought it was interesting after those two large ones today.

The real worry here is: What is it going to do with the breaks? They are already much different since the big quake some years back.

Not sure how tightly or loosely the plates are fitted together and whether the magma beneath can get a wave in it that can disurpt plates further away. We need to call in an expert on plate tectonics.
I'm just thankful that we have almost completely recovered from the devastating quake that struck Virgina and Maryland this past summer.

Supposedly this quake was from horizontal plate movement and not vertical, so no real worry about a tsunami. From my limited understanding as a beach-chair plate tectonics "expert," I am led to believe one plate just slid further over the top of another at a convergence zone as a result of the pressure created from the quakes a few years back that occurred at a divergence zone.
Oceanography were the best courses I ever took in high school and college, proven by the fact I actually remember them many years later....

But yeah..i went to Sumatra, Nias, Banyaks etc in 2007 about 9 months after the December 2006 quake and our boat captained point out how different some of the breaks we were surfing were due to the earthquake. In some places, he would point out a lava reef maybe 1/2 mile long and exposed 6 feet above the ocean, and would mentioned that it had been completely submerged prior to the quake and the entire length of it had literally been shoved up vertically like 10 feet.

Not enough data to look to, but I think it's been proven that a massive earthquake on one side of the world can trigger earthquakes very far from the original epicenter. The large magnitude quake in Indonesia last week triggered two smaller quakes in Bakersfield, CA. It relates to how the waves propagated by the quake travel through the Earth. Waves are refracted by the mantle and core and literally travel through the center (not quite center really) of the Earth. Also, not to say the Indo quake was related to the Mexican quake, but its not impossible. Just look at the size of the Pacific plate. Its almost as big as the Pacific Ocean area wise.
