- Abstract:
- The spatial evolution of 40 years after the Tangshan M7.8 earthquake shows that the aftershock distribution is uneven.There was no M4 earthquake near the epicenter region since 1996.The M4 earthquake has formed a new dense area near Zhaogezhuang to Zhenzizhen in the eastern end of the main seismic fault,and the M5.2 earthquake in 2012,the M4.8 earthquake in 2010 occurred in this region.In view of these characteristics shown in the aftershock spatial distribution images before 1996,through the aftershock spatial distribution,previous research results,stress status of the fault zone,and site inspection and other works,we comprehensively analyze the seismic distribution characteristics and tectonic significance of the northern segment of the Tangshan fault.At the same time,the old faults from Zhaogezhuang to Zhenzi Town have new activity characteristics.In the future,moderate earthquake may occur in Guye and its adjacent areas.
