Mapping spatial variability of the frequency
... To map the constants in the FMD in detail, we need as many events as possible, to be able to analyze small sub-volumes. The size of the volumes can also be reduced by limiting the numbers of events per sample. However, small sample sizes result in large uncertainties in the estimate of b. In Figure ...

What Are Seismic Waves?
... There are several different kinds of seismic waves, and they all move in different ways. The two main types of waves are body waves and surface waves.

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.
