用α径迹法监测龙门山断裂带中段地震活动被引量：1
《四川地震》1994年第2期52-55,共4页刘太平 马明理 
在龙门山断裂带中段的北川地区进行了土壤氡浓度随时间的动态变化定点观测。初步研究资料表明：土壤氡浓度变化与气象因素有密切的相关性；场地环境对氡浓度有一定的影响；探片照射方式不影响探测结果；土壤氡浓度变化能较好地反映北川...

四川省跨断层大地形变测量异常与地震
《四川地震》1994年第2期34-39,共6页廖敬梅 郭科 
通过对全川跨断层大地形变测量台、点观测数据进行全面计算处理和分析，找出四川省地形变异常尤其是中、短期异常的若干特征及其与地震的关系。这对于今后的地震预报工作无疑具有实际意义。

Coseismic displacement estimate of the 2013 M_S7.0 Lushan, China earthquake based on the simulation of near-fault displacement field
《Earthquake Science》2016年第6期327-335,共9页Hong Zhou 
supported by the Earthquake Public Welfare Scientific Research Special Project (No.201408014)
Usually, GPS observation provides direct evidence to estimate coseismic displacement. However, GPS stations are scattered, sparse and cannot provide a detailed distribution of coseismic displacement. Strong ground mot...
