Aug 4, 2020 · According to empirical structural-damage survey data from the Wenchuan earthquake (Mw = 8.0) that occurred on 12 May 2008 in China, the European Macroseismic Scale (EMS)-98, Medvedev, Sponheuer, and Karnik (MSK)-81, and Chinese Seismic Intensity Scale (CSIS)-08 intensity scales were utilized to evaluate the resulting damage. What’s the difference between geologic hazard and risk? Geologic hazards are naturally-occurring phenomena capable of causing loss or damage. Risk is the potential that exposure to the hazard will lead to a negative consequence such as loss of life or economic loss.To illustrate the difference, consider the following two examples.

California …The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes.Unlike with the Richter scale, the Mercalli scale does not take into account energy of an earthquake directly. Rather, they classify earthquakes by the effects they have (and the destruction they cause). When there is …The strongest earthquake on record was a magnitude 9.5 in Chile in 1960, according to the USGS. More than 15,000 people have been reported killed and tens of thousands of others injured by the ...The PAGER Earthquake Impact Scale. PAGER uses a new Earthquake Impact Scale (EIS) that is based on two complementary criteria. The first criterion is the estimated cost of damage; this is most suitable for domestic events and those in earthquake-resistant communities. ... 100, and 1,000, respectively.

The higher the number, the more powerful the earthquake and the higher the chance that it will cause real damage.The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10 with 10 being the greatest strength or magnitude. Different magnitudes of ...

Field survey is a labour-intensive way to objectively evaluate the grade of building damage triggered by earthquakes. In this paper, we present a decision-tree-based approach to classify the type of building damage by using multiple-source remote sensing from both pre- and postearthquakes. Specifically, the boundary of buildings is …Major earthquake. Serious damage. 20: 8.0 or greater: Great earthquake. Can totally destroy communities near the epicenter. One every 5 to 10 years: The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the energy released by an earthquake. The Richter scale, developed in the 1930s, is a base-10 logarithmic ...Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. Intensity scales date from the late 19th and ...The Fujita scale (F-Scale; / f u ˈ dʒ iː t ə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the …
