It's a little theory I like to call "Plate Tectonics." A major plate moved 30-55 feet in December. That's ridiculous. That's the kind of movement that generally takes centuries of "normal" earthquake activity to produce. And it's not some isolated system. Even though it was a quarter of the way around the world, all of these plates are interconnected and every movement affects those around them. Most of the time, that affect is miner and part of the general cycle of things. But a 9.1 quake HAS to have some far reaching affects.

Look at the earthquake activity since yesterday's Yucaipa quake. Specifically, look at the area around Sunday's Anza quake. Since the Yucaipa quake, the Anza zone has been more active. Rather, it's been the same frequency of shaking but with more intensity. Since Sunday, there have been a steady stream of small quakes, most of which have been below 1.5, the largest being 2.6. Since yesterday, the frequency of temblers >1.5 has increased, and there have been several of 2.6 or greater, including a 3.4.

Yes, it's circumstantial, but it doesn't take a whole lot of research to say "If this hunk of rock over here moves, and it's a) touching this other hunk of rock and b) causes this other hunk of rock to shake, then there's a good chance this other hunk of rock is gonna move too." And the recent activity supports that. Nevermind that whenever there's a large earthquake, almost invariably they are followed by increased activity on surrounding faults, even if those faults aren't directly connected to the fault causing the initial event.

Okay, so we have some evidence in a small area that larger than average earthquakes affect activity elsewhere, albeit somewhat geographically close. Now, yesterday's quake was a 4.9. The Indian Ocean quake was a 9.3. The scale is logrithmic. Every full point on the scale is a magnitude of 10 increase in strength. So, doing the math, the tsunami-inducing quake was 40,000 times stronger than yesterday's.

Definitive proof? No. But I stand by my statment. It's not surprising.
