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 ...The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes. Although there is only one magnitude for a specific earthquake, there may be many values of intensity (damage) for that earthquake at different sites. A magnitude 6.0 quake releases approximately as much energy as 6,270 tons of TNT, a magnitude 7.0 199,000 tons, a magnitude 8.0 6.27 million tons and a magnitude 9.0 99 million tons.
