Earthquake forecasting from paleoseismic records. [PDF]
Nat CommunAbstractForecasting large earthquakes along active faults is of critical importance for seismic hazard assessment. Statistical models of recurrence intervals based on compilations of paleoseismic data provide a forecasting tool. Here we compare five models and use Bayesian model-averaging to produce time-dependent, probabilistic forecasts of large ...

Earthquake forecasting and its verification [PDF]
, 2005 No proven method is currently available for the reliable short time prediction of earthquakes (minutes to months). However, it is possible to make probabilistic hazard assessments for earthquake risk. These are primarily based on the association of small

Residual analysis methods for space--time point processes with applications to earthquake forecast models in California [PDF]
, 2011 Modern, powerful techniques for the residual analysis of spatial-temporal point process models are reviewed and compared. These methods are applied to California earthquake forecast models used in the Collaboratory for the Study of Earthquake ...

Forecasting Southern California Earthquakes
Science, 1982 Since 1978 and 1979, California has had a significantly higher frequency of moderate to large earthquakes than in the preceding 25 years. In the past such periods have also been associated with major destructive earthquakes, of magnitude 7 or greater, and the annual probability of occurrence of such an event is now 13 percent in California.

Forecasting post-earthquake rockfall activity
Journal of Applied Geodesy, 2022 Abstract Important infrastructure such as highways or railways traverse unstable terrain in many mountainous and scenic parts of the world. Rockfalls and landslides result in frequent maintenance needs, system unreliability due to frequent closures and restrictions, and safety hazards.

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 ...

Forecasting earthquakes, [PDF]
Geophysical Journal International, 1946 It was twelve minutes after five in San Francisco on the fateful morning of April 18, 1906. Most of the city’s inhabitants were still in bed when the earthquake struck and the Great San Francisco Fire was started. Why was the public not warned of the coming catastrophe?
