| Abstract: | he definition of hazard-consistent scenario earthquake suggested by other authors is discussed firstly.According to their definition,the exceeding probability of the ground motion intensity,caused by scenario earthquake,is not keep consistent with the hazard level deduced from the seismic hazard analysis.Then a new definition of probability-consistent scenario earthquake and a method for determining the magnitude,epicentral distance and epicentre of the scenario earthquake is proposed in this paper.The probability-consistent magnitude M(p0) and probability-consistent epicentral distance R(P0) are defined as conditional mean values corresponding to that the ground motion intensity equals y(p0), the level is determined from p0,a probability of exceedance obtained from a conventional seismic hazard analysis. |
