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。

The role of epsilon for the identification of groups of earthquake inputs of given hazard
, 2008 Response spectra have been used in the years not only to obtain estimations of the seismic response for given dynamic system in response spectral analysis, but also as a useful reference for the identification of design time-history inputs (when time ...

Estimating Consumer Valuation of Earthquake Risk: Evidence from Japanese Housing Markets [PDF]
The relationships between seismic risk and rental and owner- occupied housing prices in the whole of Japan are examined. The empirical results from hedonic regressions with earthquake risk indices suggest that: (1) earthquake occurrence probability has a

The 2010 Chile Earthquake: a five-year reflection
, 2015 At 3:34AM local time, on February 27th, 2010, a moment magnitude Mw 8.8 megathrust earthquake struck offshore the coast of Chile. The earthquake ruptured a 540 by 200 km mature seismic gap of the underlying subduction pacific plate interlocking mechanism.

Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...
