开展活断层研究的意义我国是一个地震活断层广泛分布的国家,地震活动频度高,强度大,地震灾害十分严重。随着社会经济的高速发展,城市建设速度加快,社会财富迅速聚集,人口高度集中,城市地震造成的破坏及损失明显呈上升趋势。城市下方的断裂带活动是引发城市地震的元凶,地震发生 The Significance of Carrying Out Active Fault Research Our country is a country where seismic active faults are widely distributed. The frequency of seismic activity is high, the intensity is strong, and the earthquake disaster is very serious. With the rapid socio-economic development, urban construction accelerated, social wealth gathered rapidly, and the population was highly concentrated. The damage caused by urban earthquakes and the losses were obviously on the rise. The rupture zone activity below the city is the culprit that caused the urban earthquake and the earthquake happened
