← GeographyWhich outcome occurs when megathrust earthquakes initiate rupture?
A)Tsunamis propagate offshore transoceanically.✓
B)Seismic waves exhibit minimal intensity.
C)Transform faults steadily creep.
D)Oceanic crust density decreases dramatically.
💡 Explanation
Tsunamis propagate offshore transoceanically because megathrust earthquakes trigger elastic rebound violently, displacing immense water volumes. Therefore, tsunamis are generated rather than minimal seismic intensity, because those earthquakes release significant energy at plate boundaries.
