I'm sure that with Haiti, Chile, and other countries - as well as the U.S itself - appearing in the news quite frequently for Earthquakes, you may find yourself asking "Where are all of these coming from?"
And for you skeptics, it's not just the media throwing catastrophe in our faces. There are a tremendous amount of Earthquakes happening, more so than in recent history.
So what is an Earthquake? Why are they happening more frequently now? In it's most simple definition, an Earthquake is the result of a release of energy caused by friction and pressure in the Earth's crust. This release of energy rattles the ground; a large-scale version of pushing (or grinding/pulling) two pieces of paper together.
So what's up with there being more earthquakes? We're likely just experiencing a part of a cycle where the Earth's tectonic plates are shifting more as a whole. Alternative views include a super volcano being due to erupt, or it could even be apart of the world starting to end due to 2012 (If you jump on those theories).
