Deep Underground Science and Engineering, EarlyView.Three sets of strength data were selected, including hydrostatic pressure independent within the brittle region (HPI‐B), hydrostatic pressure dependent within the brittle region (HPD‐B), and hydrostatic pressure dependent within the brittle–ductile region (HPD‐BD). For HPI type, the failure envelope within the deviatoric plane remains constant.

Quasi-real-time earthquake relocation and monitoring in the northeastern Noto Peninsula
Earth, Planets and SpaceThe seismicity rate markedly increased in the northeastern Noto Peninsula of Ishikawa Prefecture around the end of 2020, with an Mw6.2 event on 5 May, 2023, followed by many aftershocks.

A New Method for Large-Scale Landslide Classification from Satellite Radar
Remote Sensing, 2019 Following a large continental earthquake, information on the spatial distribution of triggered landslides is required as quickly as possible for use in emergency response coordination. Synthetic Aperture Radar (SAR) methods have the potential to overcome

Earthquake Risk and Earthquake Insurance
Hokengakuzasshi (JOURNAL of INSURANCE SCIENCE), 2008 地震リスクには，他のリスクと比較してさまざまな特性があり，そのために保険困難な要素が多い。これを克服するために，空間的リスクに加えて，時間的リスクを大幅に取り込むことで，リスク分散を実現しようとする。しかしこれは，保険原理の観点からは，重大な問題を含んでいる。そこで，本稿では，非常に特異な性質を有する地震保険について，保険原理に照らしながら，構造的特徴ならびに限界について考察しながら，官民役割分担のあり方について論じる。とりわけ，地震保険に見られる逆選択現象の本質を捉えつつ，その対処策として採用されている地域別料率について，過度の採用は水平的不公平を増大させる恐れがあることから，むしろ，耐震構造に対するウェイトを高めた料率設定を行うことが，契約者間の公平性に照らして望ましいことを主張する。

Deep Underground Science and Engineering, EarlyView.Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

Earth, Planets and SpaceUnderstanding the rupture process of large earthquakes is critical; however, standard rupture process inversions require stabilizing constraints, which can obscure which features are genuinely required by the data.

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Deep Underground Science and Engineering, EarlyView.Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...
