Answer:
Earthquake and tsunami warning systems both monitor the same thing: seismic waves. Seismic data takes the Earth's pulse directly, so when the earth shakes, we get immediate feedback. If all goes well, we have enough time to run.
Step-by-step explanation:
An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
A tsunami or tidal wave is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
