Recent space geodetic and gravimetric studies have given indications that the Earths radius is increasing at 0.1-0.4 mm yr~(-1) at present. Seismic studies have also shown that earthquakes alone could
Earthquakes perturb both the ocean bottom topography due to displacements of sea floor and the geoid due to mass redistribution, which induces the relative sea level(RSL) change. However, the relative
