上海地区电磁辐射信号特征及其与大震的关系研究
Electromagnetic Radiation Signal Characteristics in Shanghai Area and Its Relation to Strong Earthquakes
摘要
Abstract
Four sets of electromagnetic disturbance receivers were mounted on four stations in 2008 in the Shanghai region.We collected the observation data from the receivers in the five recent years and analyzed the energy strength characteristics of the abnormal signals,including the lightning signal,the high-voltage transmission signal,and the industrial source signal.The results indicate the following.(1)In Shanghai city and its surrounding area,no electromagnetic radiation source can increase the energy of the electromagnetic disturbance observation field over 1 000 mV/km.(2)Thirty-one groups of abnormal signals of electromagnetic disturbance obser-vations at Qingpu station are obviously different from other abnormal signals,and these have characteristics of short-term earthquake precursory anomalies.(3 )Comparative analysis reveals that the electromagnetic signals generated before strong earthquakes are able to propagate over a long distance of more than 800 km,and sometimes,even more than 2,000 km.关键词
