Ground Subsidence Following Groundwater Drawdown by Excavating of 500 m Deep Investigation Shafts in Granite Body in Mizunami, Central Japan in 2004-2012
Autor: Fumiaki Kimata, Yasuhiro Asai, Toshiyuki Tanaka, Rikio Miyajima, Ryo Honda, Hiroshi Ishii
Publikováno v: Engineering. :424-433
Two 500 m deep investigation shafts were excavating in the granite body in Mizunami, central Japan by JAEA (Japan Nuclear Cycle Development Institute) in 2004-2012. Groundwater with volume of 700 m3 was generally pumping a day to prevent the shafts f

Coseismic change and precipitation effect in temporal gravity variation at Inuyama, Japan: A case of the 2004 off the Kii peninsula earthquakes observed with a superconducting gravimeter
Autor: Shuhei Okubo, Kazunari Nawa, Isao Yamada, Rikio Miyajima, Naoki Suda
Publikováno v: Journal of Geodynamics. 48:1-5
Coseismic gravity change, correlated with the 2004 off the Kii peninsula earthquakes (∼M7), was detected with a superconducting gravimeter installed at the Inuyama station of Nagoya University, central Japan, where distances from epicenters were
