摘要
对1990年以来发生在甘肃祁连山地区MS5以上地震前甘肃省内各前兆学科的异常特征进行了分析研究,发现它们在时空变化上具有协调性特征,但MS6以上地震与MS5～6地震的协调性表现虽然有许多相似的地方,仍存在很明显的差别。
Through studying on characters of muliti-subject precursors before moderately strong earthquakes in Qilian area, Gansu province, since 1990, it is found that all kinds of precursors show harmonious character in temporal-spatial. The harmonious characters for Ms ≥ 6 earthquake are obviously different from that for M s5.0-5.9 events, althought there are similar characters in both.
