Computing Scheme of Co-seismic Change of Deflection of the Vertical and Applied in the 2010 Chile Earthquake

摘要: This paper introduces a scheme to compute co-seismic change of deflection the vertical. To compare theoretical changes with GRACE-observed ones, dislocation Love numbers are truncated and Green’s functions computed application Gaussian filter. study further examines problem seawater correction modeled geoid changes. As an theory computing scheme, we consider 2010 Chile earthquake (Mw8.8) using two fault slip models, considering corrections. Results indicate that can be detected clearly by GRACE observation, is not sensitive models; whereas sensitive. These behaviors provide us new useful approach invert seismic faults as constraints.
