本文主要介绍近几年来国外利用地质构造资料和某些地球物理成果在评价地震危险性上取得的新进展。活断层各种参数与大地震之间的区域性关系式,为地震区划中未来地震的地点,强度和重复周期的确定提供了定量依据。重力、地热资料与地震在某些特定地区有一定的相关性,也有助于区划中未来地震发生地点和强度的确定。
This article mainly introduces the new progress made in the evaluation of earthquake risk by using the geological structure data and some geophysical achievements abroad in recent years. The regional relationship between the various parameters of the active fault and the large earthquakes provides a quantitative basis for the determination of the location, intensity and repetition period of future earthquakes in the seismic zoning. Gravity, geothermal data and earthquakes in some specific areas have some relevance, but also contribute to the zoning of future earthquakes to determine the location and intensity.
