- Abstract:
- By the recorded first-motion mark data of simulated earthquake made by telemetering seismostation net of Daqiao reservoir and the survey of small earthquakes' focal mechanism parameter of bridge reservoir according to years and different time buckets,we seek for the principal compressive stress's variation of 4.6 magnitude earthquake.After extracting P axis and T axis on the basis of 1 605 first-motion marks of 689 earthquakes in 10 years,it is finally demonstrated that P axis azimuth approaches the major earthquake's P axis azimuth more and more along with the time since sluicing to the major earthquake's occurring; the solution precision is high and the ratio of contradictions signs will become smaller when approaching the major earthquake; and T axis azimuth keep relatively consistent with that before the major earthquake.
