... Abstract The Kumamoto earthquakes in April 2016 have triggered numerous damages to the Tawarayama Tunnel in Kumamoto Prefecture, Japan. Distribution and characteristics of these seismic damages have been investigated and summarized to assess potential influencing factors. While some...

... commission, the first report of which has been delivered in 2015. 1. Introduction The Fukushima Daiichi nuclear power plant was seriously damaged by the Great East Japan Earthquake (moment magnitude 9.0) which occurred on March 11, 2011. The earthquake generated a giant tsunami with a run-up height...

... (and sometimes in the sea and the atmosphere). Like other dynamic fracture (rupture) phenomena in solids, however, an earthquake or rupture of solid Earth mostly occurs at a "concealed" place and even when dynamic rupture can be observed, its high-speed development cannot be followed by normal video recording...

... Abstract Following the 22 February 2011 earthquake in Christchurch significant rockfall, cliff collapse and landslides occurred around the Port Hills. Rocks from numerous bluff systems and individual outcrops above Evans Pass Road fell and collapsed ending up on or impacting the road. Evans...

... Abstract Huge earthquakes can pose serious risks even for rock tunnels, as evidenced by large earthquakes in the past. In a large earthquake in Japan in 2004, some tunnels suffered severe damages including collapse of their permanent lining, even though the tunnels were constructed in ordinary...

... Abstract Earthquakes pose a significant hazard to nuclear power plants as seen from the damage to Fulcushima I Nuclear Power Plant from the magnitude 9.0 Mw Tōhoku earthquake and subsequent tsunami on March 11, 2011. In addition to offering significant advantage in terms of containment...

... Abstract India has 2% of the total land area of the world but supports morethan 17% of global population. Due to diverse geological environment and geodynamic processes, the country faces several types of geohazards including earthquakes, landslides, tsunami, glacial lake outburst floods...

... Abstract While the fracture (rupture) dynamics of strike-slip earthquakes has been clarified to a practically acceptable level, the mechanical characteristics of shallow dip-slip seismic events remain unexplained owing to the shortage of the near-field seismological observations...

... Abstract Rock stress was measured in situ in the Kamaishi mine in Iwate Prefecture to quantify the variation in the shallow crustal stress field associated with the 2011 Tohoku-oki earthquake. Stress was measured by the Compact Conical-ended Borehole Overcoring (CCBO) technique, which is one...

... m length and the maximum highest of 96 m. The construction of the project was started in 2006 and was completed and commissioned in 19th December 2010. About a year after commissioning, the dam of the project experienced a serious leakage problem. In addition, series of earthquakes occurred within...

... Abstract How to find out the segment with stress buildup and possible seismogenic information on a fault belt is one important basis for the prediction of long-to-middle term earthquake risks. To analyze the earthquake from the viewpoint of stress buildup in the upper crust is helpful...

..., in the recent earthquakes which had caused a lot of structural damage, some cases where tunnel structures had been damaged had been also reported. So, the aseismic design for the structures constructed in rock mass should be discussed as an important and urgent problem, especially for the new structures which...

... methods used for stability assessment of these structures. The outcomes of these studies are presented and their implications on the stability of historical masonary structures in Ryukyu Archipelago under dynamic loads such as those induced by earthquakes are discussed. Reservoir Characterization...

... Abstract This paper shows five case studies of the dynamic behavior of tunnels caused by the Hyogo-ken Nanbu earthquake (M = 7.3) occurring in Kobe, Japan, in 1995. The epicenter of this earthquake was shallow and 15 km underneath the tunnels. Right after the earthquake, a field observation...

... rock engineering structures caused by the earthquakes. The authors present the outcomes of laboratory model experiments and compiled case history data in this article and their implications are discussed with the consideration of practical situations. The adverse effects of fault breaks on rock...

... Abstract Earthquakes are normally related to pre-existing discontinuities (e.g. faults, boundaries between tectonic plates), which implies an essential role of pre-existing faults in earthquake activity. Modern understanding of the nature of earthquakes is that the primary mechanism comprises...
