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。

Dizhen xuebao, 2023 在对地铁杂散电流产生机理的讨论的基础上，定量计算了地铁运行时杂散电流在地电阻率观测中所呈现的影响幅度，结果表明地铁杂散电流传播范围可以达到几十甚至上百千米。通过对城市周边的北京通州、天津青光、宝坻、塘沽、江苏江宁和辽宁新城子等六个地电阻率观测台站观测到的该类信号的研究，分析了其幅值、主要频率范围以及空间分布特征，结果表明该类信号的幅值从几mV至几十mV不等，与源距关系密切，周期主要集中在50—200 s范围内，在分析地震异常前兆信号时该类信号可使信噪比降低10—30 dB左右 ...

Earthquake Forecasting and Earthquake Preparedness [PDF]
International Journal of Earth & Environmental Sciences, 2016 Earthquake prediction is usually dealt with in one of two ways: the prediction of the effects of a postulated earthquake on a specific site or the prediction of the occurrence of events. The first approach is today well developed and should always be instrumental for the design and implementation of construction codes and for general planning.

Sea temperature variation associated with the 2021 Haiti Mw 7.2 earthquake and possible mechanism
Geomatics, Natural Hazards & Risk, 2022 A catastrophic earthquake (magnitude Mw 7.2) occurred on 14 August 2021 in Haiti. Sea surface temperature (SST) and sea potential temperature (SPT) observed from satellites show pronounced changes prior to the main earthquake event.
