Slow-motion interplate slip detected in the Nankai Trough near Japan

Source: Science Daily

Researchers used a Global Navigation Satellite System-Acoustic ranging combination technique to detect signals due to slow slip events in the Nankai Trough with seafloor deformations of 5 cm or more and durations on the order of one year. These events generally occurred on the shallow sides of regions with strong interplate coupling and represent variations in interplate friction conditions, which may help simulate the occurrence of megathrust earthquakes originating from this subduction zone and contribute earthquake disaster prevention.
