Earthquake happen because of moving tectonic plates...?? duh, **** happens because one eats things, and then **** it out. Please, this person is worried about 2012, not asking for a lecture on plate tectonics...
The reason it may seem to you that earthquakes are happening more often could be because of the increased availability and immediacy of the media, in other words it seems like more earthquake is happening simply because more earthquakes are being reported, you hear about it more, while earthquakes like that or worse have probably happened over the past, but with less media exposure, less people know about it. Even though the amount of earthquakes happening throughout history haven't really changed.
Also the human brain is good at making associations and perceiving something as more probable than they really are, for example people who have seen pictures of airplane accidents refuse to ride in planes, yet continue to drive cars which is much more likely to get them killed than travelling by airliners probably ever will. Pictures of earthquakes scare you, so your brain makes you think it's more likely to happen to you, sort of as a survival mechanism, even if it doesn't match reality. If there's a report on how there are less hurricanes happening these days than a few thousand years ago, you wouldn't give a ****, because giving a **** about it won't make you more likely to survive.
So don't worry about it too much, unless you're crazy like me and actually want it to happen for the excitement and thrill of it all. But unfortunately the chance of the so called 2012 prophecies actually coming true is pretty slim. I wouldn't rule it out though, but I would say that OJ Simpson is more likely to be innocent than the Earthquakes being related to 2012 prophecies... But if it doesn't happen by some reason, then good luck to ya.
