Post-earthquake assessment of moderately damaged reinforced concrete plastic hinges
, 2020 Modern reinforced concrete buildings are often designed to dissipate energy during strong earthquakes by permitting the controlled formation of plastic hinges. Plastic hinges require assessment of residual capacity in post-earthquake situations. However,

Dizhen xuebao, 2019 为了研究吉兰泰断陷盆地周缘断裂带气体排放及其对断层活动性的指示意义，在盆地周缘4条活动断裂上布设了5条土壤气测量剖面和1条电磁测量剖面，观测了土壤气中Rn，Hg和CO2的浓度、释放通量和地电阻率，对各测量剖面进行了土壤化学组分分析，计算得到了断层活动性相对指数KQ。研究结果显示：土壤气体CO2和Rn受渗透性较低的粉砂土阻挡，主要沿结构破碎的断层上盘逃逸，并形成浓度高峰；吉兰泰盆地南缘土壤气Rn，Hg和CO2的浓度和释放通量最高，可能与盆地西南缘花岗岩中U和Ra的运移以及盆地南缘碳酸盐岩的分解有一定的关系。

Applying the Coulomb Failure Function with an optimally oriented plane to the 2008 Mw 7.9 Wenchuan earthquake triggering [PDF]
, 2010 The Coulomb failure function (CFF) quantitatively describes static stress changes in secondary faults near the source fault of an earthquake. CFF can be employed to monitor how static stress transfers and then shed some light on the probability of ...

A comparison of the governance landscape of earthquake risk reduction in Nepal and the Indian State of Bihar [PDF]
, 2016 On 25 April 2015, a Mw 7.8 earthquake struck central Nepal, killing more than 8,700 people. An earthquake of this magnitude has long been anticipated in Nepal and the neighbouring northern Indian state of Bihar, which straddle the active Himalayan ...

Uneven aftershock distribution of Wenchuan Ms8.0 earthquake and possible mechanism
Geodesy and Geodynamics, 2011 The aftershock activity of Wenchuan Ms8.0 earthquake showed different spatial and temporal distributions along two different segments of the Longmenshan fault. This difference was likely the result of segmentation of the earthquake rupture process, which
