High-rate coseismic displacements from tightly integrated processing of raw GPS and accelerometer data

摘要: High-rate GPS and seismic sensors are mutually contributing to seismological applications for capturing earthquake-induced coseismic displacements. In this study, we propose an approach tightly integrating strong motion data on raw observation level increase the quality of derived The performance proposed is demonstrated using 5 Hz high-rate 200 collected during El Mayor–Cucapah earthquake (M w 7.2, 2010 April 4) in Baja California, Mexico. new not only takes advantages both sensors, but also improves reliability displacement by enhancing integer-cycle phase ambiguity resolution, which very critical deriving displacements with highest quality.
