在总结了鄂尔多斯地区构造特征的基础上,提出构造力学性质与地震强度之间有以下关系:(1) 在以张性为主的断裂和断裂带上,可能发生的地震的最大震级一般小于7级;(2) 在扭性特征显著的断裂和断裂带上发生的地震的最高震级可达到8级;(3) 在具有明显压性特征的断裂和断裂带上,发生地震的震级大于8级,可达8 1/2级。根据这一规律,对鄂尔多斯地区不同震级的潜在震源区进行了预测。 Based on the tectonic features of Erdos region, the following conclusions are put forward: (1) The maximum magnitudes of earthquakes that may occur on Zhang-dominated faults and faults are generally less than 7 Level; (2) the highest magnitude of the earthquakes that occur on the fault and fault zone with significant torsional characteristics can reach 8 levels; (3) on the faults and fault zones with obvious compressive characteristics, the magnitude of the earthquakes is greater than 8 Up to 8 1/2 levels. According to this law, potential source regions of different magnitudes in Ordos are predicted.
