There is alot we don't understand about earthquakes. To be honest, the "more earthquakes lately" is probably more related to them occuring closer to the U.S. and people caring therefore. If you go into google earth, you can pretty much see all of the plates and their boundaries, you'll notice the precarious situation of the Carribean plate. The Nazca (i think) subducting beneath South America has its quarks too, I think it is subducting in a style that is pretty violent, which is why some of the biggest earthquakes ever occur there.

So What! All of those are active seismic areas. For some perspective, here are the quakes from the last week for the area*. Notice the Baja region.
Here are the quakes from last week for the globe greater than mag 4. I counted 21.*
Nothing unusual... par for the course.

You are misinterpreting the facts. The quakes FELT in Phoenix occurred in the Baja region. What you felt were the seismic wave as they passed your area. And, there are quakes in Arizona.

As for the OP. The planet has these big plates that float around and bump into each other. Every so often they catch and don't move. Once the pressure builds up they slip past each other. Considering the scale at which they move there is a lot of shaking and stuff. People notice. People in highly developed countries with media companies that present everything that happens a disaster so their ratings go up and they make more money are besieged with how terrible it all is. 
I'd listen the posters here that can state the facts as opposed to those trying to make more money...  |

Well, Im sorry. But the Tuscon Seismic Center has recorded three earthquakes, with the epicenter about 2 miles below the surface, and 4 miles away from central Phoenix. The closest very active fault is the Bright Angel Fault, near the Grand Canyon. The closest fault that is not currently active is the Maricopa Fault. The last major earthquake in arizona was near wickenburg several years ago. this was recorded over 5 magnitude.

Tuscon is in southeastern Arizona. It is the second largest metro area in arizona and is surrounded by the sky islands, such as the Santa Catalinas.
