Static Stress Triggering Effects Related with M_s8.0 Wenchuan Earthquake     

朱航  闻学泽 《中国地质大学学报(英文版)》2010,(1)

In this article, firstly, we calculated and analyzed the patterns of Coulomb stress changes induced by a sequence of strong earthquakes that occurred in Songpan (松潘), Sichuan (四川) Province in 1973 and 1976, and discovered that the Ms8.0 Wenchuan (汶川) earthquake of 2008 was epicentered in a relevant Coulomb stress triggering zone. This suggests that the Coulomb stress on the middle and southern segments of the Longmenshan (龙门山) fault zone increased after the Songpan sequence of strong earthquakes, and the st...  相似文献   

Earthquake recurrence on whole active fault zones and its relation to that on individual fault-segments   总被引：1，自引：0，他引：1

IntroductionEarthquake recurrence models established on activity behaviors of strong earthquakes are the bases of long-term earthquake prediction, seismic risk zonation, and seismic hazard assessment. A lot of studies have been carried out on earthquake recurrence behaviors for specific seismogenic sources or fault-segments, and a series of empirical recurrence models have been proposed, such as the time-predictable model and the slip-predictable model for earthquakes repeated at the previous …  相似文献

The tectonic development of the Tarim block has experienced four stages, i. e. Earth's core accretion and block formation in the Precambrian, margin splitting, opening-closing and piecing up in the Early Palaeozoic, rift formation and plate unification in the Late Palaeozoic, and basin-mountain coupling and landform shaping in the Meso-Cenozoic, forming six ore-bearing formations and ore deposits of various genetic types in the Tianshan Mountains, Kunlun Mountains and Altun Mountains. In the peripheral areas of Tarim there are four giant intercontinental metallogenic belts passing through, the Central Tianshan and southwestern Tianshan belts in the former USSR and the Qinling-Qilian-Kunlun and Palaeo-Tethys belts in China. According to the macro-analysis on the nearly one thousand known deposits (occurrences) and geophysical-geochemical anomalies, and the information from reconnaissance in some areas, the region has very good prospects for mineral resources. Some of the metallogenic belts may well becom  相似文献
