自然类比法对张北──尚义6.2级地震序列类型和震后趋势早期判断实例
EXAMPLE OF USING NATURAL ANALOGISM TO DISTINGUISH TYPE OF EARTHQUAKE SEQUENCE AND TO DETERMINE POST-SEISMIC TENDENCY IN EARLY STAGE FOR ZHANGBEI-SHANGYI EARTHQUAKE WITH Ms= 6. 2
【摘要】 用自然类比法对1998年1月10日张北─尚义6.2级地震序列类型和震后趋势进行了早期判断,找出了与之最相似的四个序列是1976年9月23日巴音木仁6.2级地震(S17)、1996年5月3日包头6.4级地震(558)、1985年4月18日禄劝6.3级地震(S34)和1984年5月21日南黄海6.0级地震(S33)。由此判断张北地震序列为主震余震型,推算最大余震震级应在4.3~4.7之间,一个月内4级以上余震数可能在11~22次之间。实测结果张北地震最大余震震级4.6,一个月内4级以上余震数18次,均在预测范围内。
【Abstract】 Natural analogism is used to determine type of earthquake sequence and post-seismic tendency in early for Zhangbei-Shangyi earthquake with Ms=6. 2 on Jan. 10, 1998. The four earthquakes of the most similar to Zhangbei-Shangyi shock are Bayinmuren Ms6. 2 on Sep. 23, 1976, Baotou Ms= 6. 4 on May. 3, 1996,Luquan Ms 6. 3 on Apr. 18, 1985 and South Yellow Sea Ms 6. 0 on May. 21, 1984. Zhangbei earthquake is determined main-aftershock type. Predicted the most magnitude of aftershock is ML 4. 3~4. 7, number of ML ≥4 strong aftershock is 11~22 within one month. In fact the most aftershock magnitudeis ML=4. 6, number of ML≥4 aftershocks is 18 within one month. The prediction is exactly right.
