Abstract The Mw 7.0 mainshock of the 2016 Kumamoto earthquake sequence was triggered by dextral rupture of the Futagawa fault within the Aso volcanic region, Southwestern Japan. To reproduce its faulting patterns and to reveal the geological and geop

A scientific vertical borehole (borehole FDB) was rapidly drilled down to 691.7 m during September 2017 – March 2018 after the Mw 7.0 Kumamoto earthquake (mainshock), Japan occurred on 16th April 2016. This borehole penetrated the seismogenic fault

Recurrent large earthquakes related with an active fault-volcano system, southwest Japan
Autor: Koichiro Sado, Aiming Lin, Peng Chen
Publikováno v: Scientific Reports, Vol 8, Iss 1, Pp 1-10 (2018)
Scientific Reports
Based on fieldworks, trench excavation, archaeological evidence, and radiocarbon dating ages, we have identified at least three large normal faulting events within Aso caldera in the past ~3000 years, excluding the 2016 Mw 7.1 Kumamoto earthquake. Th

A New Age Assignment of Riukiu Limestone (Pleistocene) by Calcareous Nannofossils from the Borehole Cores at Irabu Island, South Ryukyus, Japan
Autor: Yoshihiro Tsuji, Koji Kameo, Kenji Konishi, Koichiro Sado, Tomoya Yuki
Publikováno v: Journal of Geography (Chigaku Zasshi). 101:127-132
Three nannofossil datum planes of the Early Pleistocen e are identified in the cores from subsurface at Irabu Island, South Ryukyus. The result allows for the first time to date the initial sedimentation of the reef-related Riukiu Limestone there. It

A Determination Method for Landslide Slip Surface Locations by using a Fuzzy Set Theory
Autor: Hiroyuki Yoshimatsu, Koichiro Sado, Hisao Fujita
Publikováno v: Landslides. 31:1-8_1
The determination of slip surface locations in landslide investigations plays the most important role, and has been generally decided by the experiences and subjectivity of the engineers.In this paper, we discuss the determination method for slip sur
