WebAlthough earthquake magnitude is one factor that affects tsunami generation, there are other important factors to consider. The earthquake must be a shallow marine event that displaces the seafloor. Thrust earthquakes (as opposed to strike slip) are far more likely to generate tsunamis, but small tsunamis have occurred in a few cases from large (i.e., > … http://itic.ioc-unesco.org/index.php?option=com_content&view=category&id=1340&Itemid=1414

WebRunup is a measurement of the height of the water onshore observed above a reference sea level. Except for the largest tsunamis, such as the 2004 Indian Ocean event, most tsunamis do not result in giant breaking waves (like normal surf waves at the beach that curl over as they approach shore). WebA typical tsunami approaching land will slow down to speeds around 30 miles (50 kilometers) per hour, and the wave heights can reach up to 100 feet (30 meters) above sea level. As the wave heights increase during this process, the wavelengths shorten considerably.
