TITLE: Measuring density profile of the Earth using atmospheric neutrinos observed by IceCube neutrino observatory
AUTHOR: *Kotoyo HOSHINA and Hiroyuki K.M. TANAKA
SUMMARY: I will present current status of neutrino absorption tomography for the Earth's density structure, using the largest atmospheric neutrino dataset taken by IceCube neutrino observatory.
TITLE: A megathrust earthquake cycle model for Northeast Japan: bridging the mismatch between geological uplift and geodetic subsidence
AUTHOR: * Akinori HASHIMA and Toshinori SATO (Chiba University)
SUMMARY: We explained the mismatch between geological uplift and geodetic subsidence observed in Northeast Japan by a simple viscoelastic dislocation model.
