    我根據第一個網址提到的一年前,已經有了關於警告中國有地震情況的研究描述,我找到了現在下面的文章。
    這是美國地球和空間科學知識網站在[地殼]部分該論文網址:http://www.agu.org/pubs/crossref/2007/2006TC001987.shtml
    
    文章作者共六人,文章的有兩個作者是中國四川的,是第三和第四作者。另外有兩名美國的,一名英國的和一名瑞士的。文章太專業,大家可用翻譯軟件翻譯一下。同時,這只是概述,不是全文,需要註冊才能看到全文。有興趣的可以去看看。重點我標成黑體,作為參考!

    Abstract概述
    
    The steep, high-relief eastern margin of the Tibetan Plateau has undergone rapid Cenozoic cooling and denudation yet shows little evidence for large-magnitude shortening or accommodation generation in the foreland basin. We address this paradox by using a variety of geomorphic observations to place constraints on the kinematics and slip rates of several large faults that parallel the plateau margin. The Beichuan and Pengguan faults are active, dominantly dextral-slip structures that can be traced continuously for up to 200 km along the plateau margin. Both faults offset fluvial fill terraces that yield inheritance-corrected, cosmogenic 10Be exposure ages of 15 kyr, indicating latest Pleistocene activity. The Pengguan fault appears to have been active in the Holocene at two sites along strike. Latest Quaternary apparent throw rates on both faults are variable along strike but are typically 1 mm yr−1. Rates of strike-slip displacement are likely to be several times higher, probably ∼1–10 mm yr−1 but remain poorly constrained. Late Quaternary folding and dextral strike-slip has also occurred along the western margin of the Sichuan Basin, particularly associated with the present-day mountain front. These observations support models for the formation and maintenance of the eastern plateau margin that do not involve major upper crustal shortening. They also suggest that activity on the margin-parallel faults in eastern Tibet may represent a significant seismic hazard to the densely populated Sichuan Basin. 他們也指出在西藏東的平行地緣斷層的運動對於人口密集的四川盆地呈現出一個顯著的地震危險。
