This gives the appropriate information on the epicentre and intensity of the earthquake. The size of an earthquake is provided on the Richter scale and the severity of damages caused by earthquakes totally depends on the magnitude of it.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. Exploring Logarithms and the Richter Magnitude Scale 17 On Earth, the severity of an earthquake is measured by the amount of ground movement that it produces. The Richter Scale has been in use for many years and is an example of a logarithmic scale. Logarithmic scales are linear scales in ‘x’ such as 1.0, 2.0, 3.0 etc, but they representThe Richter and MMS scales measure the energy released by an earthquake; another scale, the Mercalli intensity scale, classifies earthquakes by their effects, from detectable by instruments but not noticeable, to catastrophic. The energy and effects are not necessarily strongly correlated; a shallow … See more
He said, “Based upon GPS displacement data and local topography data, we generated a new tsunami scale measurement from one to ten, much like the Richter Scale used for earthquakes.”. Any tsunami measuring more than a five on this scale would merit a basin-wide warning. For instance, Song classified the tsunami generated by the 2004 Sumatra ...Schroeder et al.
