Earthquakes can be estimated by hazard maps, which are constructed by examining
· The earthquake history of the region to estimate the probability of an earthquake
· The expected shaking intensity produced by the earthquake (often expressed as a peak acceleration)
· The frequency of the shaking, the distance from the fault
· The regional geology and site conditions
Hazard mapping is to estimate the maximum level of shaking expected during the lifetime of a building. Constructing accurate hazard maps is a challenge and remains the focus of much Geoscience research.
