The Northridge Earthquake
... HOMEWORK: DETERMINE THE EPICENTER OF THE 1994 NORTHRIDGE EARTHQUAKE Seismic waves, felt as the shaking motion when an earthquake occurs, are generated when energy is released during an earthquake. The difference in time is takes for the two primary types of seismic body waves—P waves and S waves—to ...

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.
