摘要
2001年11月14日,在中国青海、新疆交界地区(35.93°N,90.54°E)发生了Ms8.1级地震.在此地震前,距震中超过2000公里的北京工业大学地震研究所(39.88°N,116.47°E)收到三种非常清晰的临震信息:次声波异常信号、地应力突变信号及虎皮鹦鹉跳动频率异常信号.
An Ms 8. 1earthquake occurred in the interface region of Qinghai and Xinjiang, China （35.93°N, 90.54°E） on October 14, 2001. Before this earthquake, three distinct imminent precursors including abnormal infrasonic wave signals, sudden change in crustal stress signals, abnormal jump frequency of the budgerigars were detected in the Institute of Earthquake Prediction Research in Beijing University of Technology （39.88°N, 116.47°E） which more than 2000 km away from the epicenter.
