The earthquake data in Xinjiang are abundant and have been widely applied to the statistic relationship of seismic intensity of western China. However, there exists some unreasonable and man_made factors in them. We put forward the idea of area A_ 0-1 to express the effect of seismic intensity, studied the questions and influencing factors arising from uncertainty of intensity zoning and finally, proposed some solutions.展开更多

Earthquake intensity, especially in the near source region, as a macroscopic description of distribution of strong ground motions certain correlations with the earthquake source process, such as rupture directivity and the hanging-wall effect of the near-fault ground motions of this earthquake. In this article some qualitative analyses are carried out. The conclusion of this study may be useful for emergence response and rescue after earthquakes, when the strong ground motion recordings and the intensity distribution are not available immediately.展开更多
At 19:33 p.m on September 27, 2003, an earthquake with M7.9 occurred in the Russia-Mongolia-China boundary Region. It was strongly felt in the Altay region of Xinjiang.

It was strongly felt in the Altay region of Xinjiang. The losses caused by the earthquake was 76 million yuan (RMB). Some information about the earthquake was outlined, including basic parameters, focal mechanism, evaluation of earthquake disaster losses and so on. The satellite remote sensing information worked initial analysis for deformation of ground and failure phenomenon.展开更多
