The post-seismic horizontal and vertical deformations following the 2008 Ms8.0 Wenchuan earthquake are inferred from GPS and precise leveling data. The post-sei
Earthquakes heavily deform the crust in the vicinity of the fault, which leads to mass redistribution in the earth interior. Then it will produce the change of the Earths rotation (polar motion and le
Optical observations from a ground-based astrometric instrument provide a unique set of data sensitive to variations of local plumb line, which represent the change of local gravitational field on the
Through theoretical derivation, some properties of the total least squares estimation are found. The total least squares estimation is the linear transformation of the least squares estimation, and th
