Two months ago we received 2010 with the news that neighboring Haiti was struck with a 7.0 magnitude earthquake. Not recovered from Haiti’s situation, in the last days of February, Chile also experiences an earthquake; this time an 8.8 one and nowadays they are still getting aftershocks. After all these events have you ever asked yourself what causes an earthquake? Can Puerto Rico be struck by an earthquake? Fortunately, the answers to all these questions and the science behind earthquakes are the focus of the research of geologists like Dr. Daniel Laó Dávila and the Puerto Rico Seismic Network.
