Hydrochemical characteristics of hot spring waters in the Kangding district related to the Lushan MS = 7.0 earthquake in Sichuan, China [PDF]
Natural Hazards and Earth System Sciences, 2015 Hydrogeochemistry of 10 hot springs in the Kangding district was investigated by analyzing cation and anion concentrations in the spring water. The water samples were collected in the 5 days after the Lushan MS = 7.0 earthquake, which occurred on 20 ...

A cluster identification framework illustrated by a filtering model for earthquake occurrences [PDF]
, 2008 A general dynamical cluster identification framework including both modeling and computation is developed. The earthquake declustering problem is studied to demonstrate how this framework applies. A stochastic model is proposed for earthquake occurrences

Rn and CO2 geochemistry of soil gas across the active fault zones in the capital area of China [PDF]
Natural Hazards and Earth System Sciences, 2014 The present work is proposed to investigate the spatiotemporal variations in soil gas Rn and CO2 across the active faults in the capital area of China in order to understand fault activities and assess seismic hazard.

Observations of stress relaxation before earthquakes [PDF]
, 2004 Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

Seismological Aspects of the December 2004 Great Sumatra-Andaman Earthquake [PDF]
, 2006 The 2004 Great Sumatra-Andaman earthquake had an average source duration of about 500 sec. and a rupture length of 1,200–1,300 km. The seismic moment, M0, determined with a finite source model, was 6.5×1022 N-m, which corresponds to Mw=9.18.

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。

THE DETERMINATION METHOD OF EXTREME EARTHQUAKE DISASTER AREA BASED ON THE DUST DETECTION RESULT FROM GF-4 DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 The remote sensing has played an important role in many earthquake emergencies by rapidly providing the building damage, road damage, landslide and other disaster information. The earthquake in the mountains often caused to the loosening of the mountains
