The event began with a powerful earthquake off the coast of Honshu, Japan’s main island, which initiated a series of large tsunami waves that devastated many coastal areas.Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are.The moment magnitude scale (Mw) is a logarithmic scale used to measure the size of earthquakes. It is based on the seismic moment, which is a measure of the energy released by an earthquake. The seismic moment is calculated by multiplying the area of the fault that ruptured by the average amount of slip and the rigidity of the rock.The colors on this map only show the hazard from natural earthquakes. In the areas with induced earthquakes, the number of occurrences of damaging shaking could be much higher than the value shown on this map, and could drop lower again if the human activities that are causing the earthquakes change.Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location.
