... Charles Richter (1935) devised a quantitative method based on the amplitude of the largest waves recorded on a seismogram. The size of the amplitude depends on: The distance from the epicenter. The intensity or magnitude of the earthquake. (Note - the amplitude can vary many thousands of time ...

Earthquake casualty estimation
Recent advances are improving the speed and accuracy of loss estimates immediately after earthquakes (within less than an hour) so that injured people may be rescued more efficiently. After major and large earthquakes, rescue agencies and civil defense managers rapidly need quantitative estimates of the extent of the potential disaster, at a time when information from the affected area may not yet have reached the outside world. For the injured below the rubble every minute counts.To rapidly provide estimates of the extent of an earthquake disaster is much less of a problem in industrialized than in developing countries. This article focuses on how one can estimate earthquake losses in developing countries in real time.
