Final answer:

The run-up and the inundation of a tsunami depend on earthquake magnitude.

Step-by-step explanation:

The run-up and the inundation of a tsunami depend on earthquake magnitude.

When an undersea earthquake occurs, it generates seismic waves that propagate through the ocean and eventually form a tsunami. The magnitude of the earthquake, which measures the energy released during the seismic event, directly affects the size and strength of the resulting tsunami. A larger earthquake magnitude will produce a more powerful tsunami with higher run-up (the maximum vertical height reached by the tsunami on land) and greater inundation (the extent of flooded area).
