Abstract: Based on the results of recent studies of earth sciences,the relationship between crustal fluids and major earthquakes is discussed,including the influence of crustal hot fluids on earthquakes,the control of mid crustal fluids to major events,the ralationship between ancient fluids activities in fault zones and seismic recycles. New ways to determine the risk of strong earthquakes are proposed according to the features of distributions and activities of crustal fluids.

摘要： 以地球科学发展的新近研究成果为基础,讨论了地壳中流体与强震活动的关系,包括上地壳热流体对强震活动的影响、中地壳流体对强震活动的控制、断裂带中古流体活动与地震活动旋回的关系,从而提出由地壳流体分布与活动特征来判定强震危险性的新途径。
