Study with Quizlet and memorize flashcards containing terms like Seismograph, Epicenter, Focus and more. Introduction. Earthquake ground motion is a natural phenomenon associated with a sudden release of energy due to a fault rupture. Strong-motion seismology deals with seismic waves radiated by large earthquakes. More precisely, it is concerned with measurement, interpretation and prediction of strong shaking generated by damaging earthquakes.The MM scale measures intensity of shaking, at any particular location, on the surface. It was developed from Giuseppe Mercalli 's Mercalli intensity scale of 1902. While shaking experienced at the surface is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves.Monday b.

Feb 15, 2020 · The intensity, or macroseismic intensity, represents a classification of the severity of ground-motion shaking during an earthquake on the basis of observed effects at a given place (Grünthal et al. 1998 ). The word “macroseismic” refers to perceptible effects of earthquakes as opposed to instrumental observations.

The Intensity Prediction Equation (IPE) is an estimate of intensity for a given earthquake magnitude and distance. Earthquakes in different regions of the world tend to create different levels of shaking for many reasons, such as the mechanism of the earthquake, the nature of the geological environment, and the quality of infrastructure. A magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake. Ranking Earthquake Intensity. Earthquake intensity is very different from earthquake magnitude. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place.Surface Wave.
