Simulating Earthquake Rupture and Near-Fault Fracture Response
, 2018 Sweden is presently a low seismicity area where most earthquakes are small and pose no serious threat to constructions. For the long-term perspectives of safety assessments of geological repositories for spent nuclear fuel, however, the effects of large earthquakes have to be considered.

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 ...

EXTENDED FRAMEWORK FOR EARTHQUAKE AND TSUNAMI RISK ASSESSMENT: PADANG CITY A CASE STUDY [PDF]
, 2013 The Great Sumatra earthquake and resulting devastating tsunami in 2004 have highlighted the significance of earthquake risk assessment that can effectively include all main associated hazards, such as tsunami.

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.
