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 ...

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 ...

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.

THE EXTRACTION OF POST-EARTHQUAKE BUILDING DAMAGE INFORMATIOM BASED ON CONVOLUTIONAL NEURAL NETWORK [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 The seismic damage information of buildings extracted from remote sensing (RS) imagery is meaningful for supporting relief and effective reduction of losses caused by earthquake.

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.

HIGH RESOLUTION SAR IMAGING EMPLOYING GEOMETRIC FEATURES FOR EXTRACTING SEISMIC DAMAGE OF BUILDINGS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 Synthetic Aperture Radar (SAR) image is relatively easy to acquire but difficult for interpretation. This paper probes how to identify seismic damage of building using geometric features of SAR.
