form and offering a new method for forecasting the powerful waves.

\r\rMost tsunamis result from a massive shifting of the seafloor -- usually from the subduction, or sliding, of one tectonic plate under another during an earthquake.

Using a large wave tank, researchers simulated horizontal land displacements and found that it can contribute significantly to the strength of some tsunamis.", "items": [], "extra_data": {} } ], "studio": "gms", "funding_sources": [ "ESE" ], "credits": [ { "role": "Producer", "people": [ { "name": "Kathryn Mersmann", "employer": "USRA" } ] }, { "role": "Writer", "people": [ { "name": "Samson K.
