If I had to bet, I'd say the next big one would be the west coast of North America, the west coast of South America, or Taiwan, mainly because these are the areas that have not seen a large earthquake in the last few months.

There have been rumblings in California for the last couple of weeks, and we know the big one is coming there sooner or later.

Something stirring in Nantou as well - if it is Taiwan, then that could be a likely spot

The other thing pointing to Taiwan is that there hasn't been any typhoons - highly unusual for Taiwan to go through a lunar year without a major natural disaster of some kind - the only one I can remember was when the SARS epidemic broke out
