运城地区地震办公室成立以来,在地委的一元化领导下,在联系实际学习毛主席关于理论问题的热潮中,在省队多次帮助和群众测报点上同志们共同努力下,做了一些工作。目前,能坚持观测记录的以土地电为主要手段的测报点共六十九个,它们分布在十三个县和一些大的地营以上厂矿。一半以上点的土地电属于多方向(但不设公用电极),一少部分的点为两个方向(即EW和SN),有的点是以平行和切割断裂带布设的。电极一般采用碳棒对金属铅极,个别地方用碳棒对金属锡极。极深一般都是3米。极距一般多为15—25米。绝大
Since the earthquake office was established in Yuncheng District, under the unified leadership of the prefectural Party committee, some work has been done in connection with the actual study of Chairman Mao’s theoretical issues. With the concerted efforts of the provincial team and comrades at the mass measurement points, some work has been done. At present, a total of 69 reports of land-based surveys, which insist on observing records, are distributed in 13 counties and some large camps above the mine. More than half of the earth’s electricity is multi-directional (but not common), with a small number of points in two directions (EW and SN) and some with parallel and cleaved fault zones. The electrode generally adopts the carbon rod to the metal lead pole, and the individual place uses the carbon rod to the metal tin pole. Extremely common are 3 meters. Polarized usually 15-25 meters. Great
