When it comes to earthquakes, certain parts of the world are at higher risk than others. Given that earthquakes are caused by friction between slow-moving tectonic plates, the parts of the world that are located on a tectonic plate boundary are at particularly high risk.
One such high-risk zone is the Nankai Trough, which is located off the southwest coast of Japan. Experts predict that we could be due a megaquake in this region very soon, and it has the potential to cause huge destruction.
