Based on the observation records of deformation stations in Ankang area from 2017 to 2020. we compared and analyzed the earthquake-reflecting capacity of six sets of instruments. and systematically discussed the relationship between the source parameters and the characteristic parameters of co-seismic deformation wave from the delay time of surface wave. the biggest shock and duration. https://ashleyshomestores.shop/product-category/slide-duel-fuel-range/
