[SCG64-P10] Sharp gravity increase following an outer-rise earthquake: possibility of viscoelastic rebound by melt-rich channel

*Koji MATSUO1, Yoichi FUKUDA1, Yoshiyuki TANAKA2 (1.Kyoto University, 2.The University of Tokyo)

Keywords:outer-rise earthquake, melt-rich channel, viscoelastic rebound, GRACE, postseismic gravity change

We are going to talk about postseismic gravity increase by outer-rise earthquakes, and explain their geophysical mechanism through viscoelastic theory.
