They especially study east Kunlun active fracture across the reservoir dam,which is a deep lithospheric fracture zone whose horizontal displacement is 40~80m,smoothing rate of speed is 7.5~9.5mm/a with many grand paleoearthquake traces.
According to engineering geological characteristics and engineering construction experiences in Guangzhou City,the main development characteristics,including geology engineering features of rock and soil mass,groundwater distribution characteristics,karst,active fracture,and the factors comprehensively affecting underground space utilization,are analyzed.
Through the analysis of geotechnical section of the drilled holes, the results of the shear wave velocity tests, the background,active rift and effects of the earthquake geology and the main earthquake proof parameter,the authors consider that construction site of the university belongs to medium soft soil which does not have the possibility of liquification and type of site can be classified as Type Ⅱ.
Robust and active fault-tolerant control for a class of nonlinear uncertain systems
Prediction of near-field strong ground motions for scenario earthquakes on active fault
It is proposed that the Cenozoic volcanism regions, rift basins, active fault belts, activated plate suture zones and large earthquake occurrence points are the best areas for prospecting geothermal resources.
The results of calculation show that the information dimension of the temporal distribution in Xianshuihe active fault zone before Luhuo large earthquake isD1=0.1051.
The information dimensions of the temporal distribution of the earthquakes in Anninghe active fault zone are respectivelyD1(tN)=0.1363 (for the north section) andD1(tS)=0.06710 (for the south section).
Seismically active fracture zones and distribution of large accumulations of metals in the central part of Andean South America
Sixteen mining districts in Chile, and 24 in Argentina, were attributed to the seismically active fracture zones.
The area is dissected by the East Azores Fracture Zone at 36°55'N, identified as the active Eurasian-African plate boundary, and by another large, non-active fracture zone at 36°10'N.
Morphology of the Wadati-Benioff zone, andesitic volcanism, and active fracture zones in Central America
Four deep seismically active fracture zones, genetically connected with the process of subduction, and three fracture zones manifesting the possible boundary between the Americas and Caribbean plates were identified in the continental wedge.
