Study on co-seismic deformation wave characteristics of crustal deformation observation records in Ankang area

Based on the observation Ball - Womens Bottoms 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, and obtained the influencing factors of the earthquake-reflecting capacity of deformation instruments and the physical distribution characteristics of co-seismic deformation wave.The result shows that the earthquake-reflecting capacity of instrument is related to the response characteristics and systematic error of instrument, the characteristics of underground medium; The physical distribution characteristics of co-seismic deformation wave show that there are linear or proportional distribution relationship in a certain degree between the delay time of surface wave and the epicenter distance of earthquakes, Bath Towels the biggest shock of co-seismic and magnitude, the duration time of co-seismic and magnitude and epicenter distance.
