Abstract

Surface deformation of the earth due to a periodic point load on the earth’s surface is re-analyzed. Firstly, the equation of motion for deformation of the whole earth due to a periodic zonal harmonic load is solved, and the load Love numbers, which are ratios between the load and the resultant perturbations, are acquired accordingly for the International Association of Seismology and Physics of the Earth’s Interior (IASPEI) earth model. The load Green’s functions are then evaluated by using the calculated load Love numbers. All the steps are verified, and the characters of the acquired load Love numbers and the load Green’s functions are inspected. A comparison is made with former studies that used dierent earth models.
