Factor that helps most people predict the force and danger of a tsunami is ?

Factor that helps most people predict the force and danger of a tsunami is obviously the developed technology we attain now.

Explanation:

Abnormal ocean activity, a wall of water, and an approaching tsunami create a loud "roaring" sound similar to that of a train or jet aircraft. If you experience any of these phenomena, don't wait for official evacuation orders. Immediately leave low-lying coastal areas and move to higher ground."

Inundation and run-up are often determined by measuring the distance of killed vegetation, scattered debris along the land and eyewitness accounts of the incident. Scientists have made great strides in monitoring and predicting the ongoing threat of tsunamis.

Deep-ocean tsunami detection buoys are one of two types of instrument used by the Bureau of Meteorology (Bureau) to confirm the existence of tsunami waves generated by undersea earthquakes. These buoys observe and record changes in sea level out in the deep ocean.

The biggest problem in predicting the size of a tsunami is in determining exactly how much energy was put into the ocean by an earthquake, and that is something that cannot be determined in the immediate aftermath of the event.

A factor that helps most people predict the force and danger of a tsunami is what some people describe as a rushing sound, and seeing what looks like a mountain in the distance. Scientists also use deep-ocean tsunami detection buoys, to monitor underwater tetonic plates.
