Puerto Rico was once again struck by a powerful earthquake Saturday morning. Puerto Rico has been experiencing earthquakes since the beginning of the new year, and you, like many others, may be wondering why. According to News 6 meteorologist Candace Campos, the reason for the recent series of quakes all boils down to the science behind earthquakes and where Puerto Rico is located. Puerto Rico is located along active tectonic plates, which are like giant puzzle pieces that make up the earth’s crust. Along with that interaction, there is also the Puerto Rico Trench, which is caused by the North American Plate sinking underneath the Caribbean Plate.
