TITLE: Preliminary results of tsunami simulation for the 21 November 2016 Fukushima earthquake (Mw 6.9)
AUTHOR: *Aditya Riadi Gusman・Kenji Satake・Masanao Shinohara and Shinichi Sakai
SUMMARY: We simulate the tsunami from the 21 November 2016 Fukushima earthquake (Mw 6.9) and compare the simulated tsunami waveforms with the observations at tide gauge and tsunami-meter stations.
TITLE: Stress response of volcano-tectonic earthquakes - relation between seismicity and earth tide
AUTHOR: *Yuichi MORITA and Hiroshi TSURUOKA
SUMMARY: Seismicity at Izu-Oshima correlates well with earth tide
TITLE: Relative sea-level changes recorded by coral microatolls over the last century in Okinawa and Yoron, Ryukyu islands
AUTHOR: * Jennifer Weil-Accardo, K. Satake, T. Goto, N. Feuillet, H. Kayanne, JM. Saurel, G. Ramos, K. Goto, M. Nakamura and K. Sowa
SUMMARY: Started in last February, our project focused on the use of coral microatolls along the Ryukyu arc allows us to bring first informations on the relative sea-level changes in Okinawa and Yoron over the last century.
TITLE: Synthesis of highly-dense and fine-grained olivine aggregates with various crystallographic preferred orientation patterns found in natural peridotites

TITLE: Geodynamic implications of the morphology of the stagnant slab from the northern Okhotsk arc to the northeastern Japan arc: Effects of subducted Izanagi plate
AUTHOR: * Satoru HONDA
SUMMARY: I discuss the effects of subducted Izanagi plate on the morphology of the stagnant slab observed from the northern Okhotsk arc to the northeastern Japan arc.
TITLE: Marine magnetotellurics imaged no distinct plume beneath the Tristan da Cunha hotspot in the southern Atlantic Ocean
AUTHOR: * Kiyoshi BABA・Hisashi UTADA, Jin CHEN・Malte SOMMER・
Marion JEGEN (GEOMAR), Wolfram H. Geissler and Wilfried Jokat (AWI)
SUMMARY: We show a three-dimensional electrical conductivity structure of the upper mantle beneath the Tristan da Cunha hotspot, which was obtained through a marine magnetotelluric experiment under Japan-Germany collaboration in 2012-2013.
TITLE: Inter-comparison exercise of volcanic eruption column models
AUTHOR: * Yujiro J. Suzuki and Antonio Costa (INGV)
