Japan's new seafloor record could sharpen megathrust earthquake warnings in Nankai Trough

Off the southern coast of Japan, the Philippine Sea Plate lies underneath the Japanese mainland. The locked tectonic plates threaten to unleash a catastrophic megathrust earthquake, likely within the next few decades. Given the potential devastation a large quake could evoke, constant developments in predictive technology must be sought. However, predicting the unpredictable movement of the seafloor requires innovative thought.
