How to measure earthquake intensity.

A modified Mercalli intensity scale is used to quantify the earthquake's effects. That's why you can't directly convert the Richter or Magnitude scale to the Mercalli scale — although the released energy, local geology, terrain, depth of an earthquake and distance from the epicenter are all still the same. Thus, the Mercalli scale describes ...The magnitude of an earthquake is a number that characterizes the relative size or amount of elastic energy released by such an event (see “Earthquakes, Energy”).It is usually based on measurement of the maximum ground motion recorded by a seismograph (sometimes for a particular wave type and frequency) and corrected for the …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 ... There are many ways to measure magnitude — including Charles Richter’s method developed in 1935 — but they are all ways to …

Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 9.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.

The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included in the magnitude formula to …The intensity, as expressed by the Modified Mercalli Scale, is a subjective measure that describes how strong a shock was felt at a particular location. 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 earthquake ...

9.8 Earthquake Risk 9.8.1 Factors That Determine Shaking. Earthquake magnitude is an absolute value that measures pure energy release. Intensity however, i.e. how much the ground shakes, is a determined by several factors. Earthquake magnitude—In general, the larger the magnitude, the stronger the shaking and the longer the shaking will last.
