One of the biggest earthquakes ever recorded struck recently, with minimal damage, no tsunami and it barely made the news. That’s because there are two kinds of earthquakes. This earthquake happened when two tectonic plates moved past each other horizontally, while more damaging earthquakes are caused when one plate slips beneath another. This radio story explains the two types of earthquakes and how they are gradually redefining the boundaries of the tectonic plates.
