WebOct 11, 2013 · Traditionally, scientists have looked at the earthquake itself—using location, magnitude, and depth—to estimate the size and direction of the tsunami. As an oceanographer, Song knew that historic records had proven this method did not always work well. “The scale of the tsunami can be different from the earthquake scale,” he said. WebThe intensity differs from the magnitude which is related to the energy released by an earthquake. There are multiple versions of the MM scale, the one listed here being the 1931 version. MM I.
