Detection of Precursory Wave Using a Novel Sensor and Its Application to Earthquake Prediction
چکیده انگلیسی

A novel precursory wave detector by using liquid-suspension principle and super-low-frequency(SLF) sound signal detection technology in submarine is presented, then the device of earthquake precursory wave detection and the corresponding software are developed. The detection devices were placed respectively in Ziwu, Qianling and Louguan in Shaanxi Province, in more that a year, all the SLF-acceleration signals were recorded continuously in real-time; A contrast analysis was made between the abnormal precursory waves and the following earthquake events. The results show that the accuracy, sensitivity and specificity of this method in earthquake prediction are 72.08%, 39.06% and 81.73%, respectively.
