Which seismic effect is amplified during megathrust subduction?

💡 Explanation

Megathrust subduction triggers significant vertical displacement of the seafloor during earthquakes, because elastic rebound transfers tremendous force at the plate boundary. Therefore, tsunamis are generated rather than landslides which are triggered by ground shaking.
