Research Abstract |
Coseismic gravity changes associated with the 2010 Chile Earthquake have been detected with GRACE satellites (Heki & Matsuo, 2010 GRL). We also detected ice loss amounting up to 40 Gt/yr in the Asian High Mountains including the Himalayan glaciers (Matsuo & Heki, 2010 EPSL). We also revealed that quadratic signals in time-variable gravity are due mainly to linear changes in precipitation (Ogawa et al., 2011 GJI).
