摘要
贵州的地震明显受(活动性)断裂控制和影响,地震的平面分布分区边界受区域断裂控制,地震多发生在断裂附近或多组断裂交汇区附近。1819年以来,贵州境内发生的4次6级左右地震,震中都在多组断裂交汇区附近。1875年6月8日发生的6.5级地震,震中在开远—平塘断裂和垭都—紫云断裂交汇区附近的床井背斜,地理位置位于罗甸县西部,紧邻望谟县和紫云县,即北纬25°18',东经106°36'。
Earthquakes in Guizhou were controlled and affected by( active) faults. The regional faults controlled the earthquake partition boundaries. Earthquakes usually occurred near faults or intersection area of many faults. Epicenters of the four earthquakes,M 6 or so,since 1819,were in intersection area of many faults. The M 6. 5 earthquake that occurred on Jun. 8th,1875,its epicenter was located at the Chuangjing anticline,intersection area of Kaiyuan-Pingtang fault and Yadu-Ziyun fault. The epicenter is located at the west of Luodian County,and is nealy Wangmo County and Ziyun County. Its longitude and latitude is 106°36'E and 25°18'N.
