The first scale focuses on the severity of damage at a locality and is called the Mercalli Intensity scale. The second focuses on the amount of ground motion at a specific distance from the epicentre, as ...Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. Earthquake shaking generally occurs in all three directions. Therefore, …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 representSeismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales , which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking. with the earthquake, tsunami, and radiological hazards in the 2011 East Japan disaster (Chapter 1.3) (4–5). Timing, severity, geographic location, and frequency are important characteristics of hazards. Hazards can have a short or long duration, and can have different impacts depending on the time of day, week or month when they happen (6).Richter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.The severity of an earthquake can vary from events which are barely detectable even using the most sophisticated devices, to devastating events which can level cities and trigger Tsunamis and sometimes even volcanic activity. The severity of an earthquake is called its magnitude.Various scales were proposed to measure the magnitude of earthquakes …The 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 moreEarthquakes happen every day, but most are so small that humans cannot feel them.

It is important to understand that the magnitude scale is not linear - it is logarithmic.Jan 1, 2016 · The size and damaging effects or severity of an earthquake are described by measurements of both magnitude and intensity. In seismology (the study of earthquakes), scales of seismic intensity are used to measure or categorize the effects of the earthquake at different sites around its epicenter. Various seismic scales can be used to measure and ... It isn't that simple. There is not one magnitude above which damage will occur. It depends on other variables, such as the distance from the earthquake, what type of soil you are on, building construction, etc. That being said, damage does not usually occur until the earthquake magnitude reaches somewhere above 4 or 5. Learn more: Glossary of …The moment magnitude scale may be a better indicator of earthquake severity especially for large earthquakes and those occurring outside of California, where the Richter scale was developed. TRUE A Benioff zone is a region of deeper earthquake foci where geometry reflects a subducting slab of lithosphere.Great earthquakes, such as the 1964 Good Friday earthquake in Alaska, have magnitudes of 8.0 or higher. Although the Richter Scale has no upper limit, the largest known shocks have had magnitudes in the 8.8 to 8.9 range. Recently, another scale called the moment magnitude scale has been devised for more precise study of great earthquakes.The Richter Scale, named after Dr. Charles F. Richter of the California Institute of Technology, is the best known scale for measuring the magnitude of earthquakes. The scale is logarithmic so that a recording of 7, for example, indicates a disturbance with ground motion 10 times as large as a recording of 6. An earthquake is a sudden shaking or rolling of the ground caused by movements under the earth’s surface. Some earthquakes can be mild while others may be severe causing massive devastation to structures, life and other natural resources.Category Related topics v t e Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake.
