Evolution of shear zones using numerical analysis at the May 12th Wenchuan Earthquake Site, China
, 2012 Landslides and collapses occurred during the May 12th earthquake in Wenchuan County. Most of these landslides and collapses were caused by shear bands. Shear band triggers instability on mountain slopes, resulting in debris flow, landslides, or collapse.

The Precursor of Wenchuan and Lushun Earthquakes That Helps to Predict Earthquake
Advances in Geosciences, 2017 是否存在“有助于预报的地震前兆”？马瑾院士由岩样加载实验发现岩石加载临近强度极值进入亚失稳阶段，发出应变、位移、温度变化特征信号，之后岩样破裂。大地震前是否能观测到这些信号？观测到了，如何识别应力已达峰值强度？姑咱地震台YRY-4分量钻孔应变仪汶川大震前550天中接收到3700多个异常应变脉冲，震后衰减。2014年底发现，脉冲出现初期，表征脉冲数据自洽性的k值大于0.99；大震前夕k值逐渐减小至0.4，数据失洽。地层连续无裂隙是应变数据满足自洽的条件，失洽是震源区地层连续性破坏越来越严重，大震将发生的标志。汶川大地震前五个月时出现5天中一个脉冲事件也没有的平静期，脉冲事件再度增多后大地震发生。岩石加载声发射现象，加载接近峰值强度出现声发射平静期，继续加载声发射再现后岩样破裂。在数千脉冲事件背景下 ...
