- Abstract
- In Part I of this report, a general analysis is made of characteristics of three strong ground motion records obtained from a moderate earthquake near Wufeng, on April 14, 1976. Both time and frequency domain techniques are used. The intensity function has a single peak shape, which suggests that the fault mechanism is simple. Using an intensity function of this shape, the general pattern of the ground motion is simulated. A comparison of these simulated motions with the recorded ground motions shows similar characteristics. In Part II of this report, the problem of risk maps is examined using the distribution of seismic intensity both in time and space in Taiwan. In this study, instead of the Poisson distribution for earthquake occurrence, a modified Hazard distribution is adopted. This distribution allows a dependence between successive earthquakes. Hazard contour maps have been drawn using this method for thirteen cases. These are compared with various risk map estimates, by other authors, having the same general tendencies.
