【摘要】 本文根据位错模型震源理论,利用18个云南地震(5.27≤m_b≤6.09) 和40个世界浅源的中、强震(6.2≤m(pv)≤7.6)震源参数,进行震级对震源参数的一元线性回归、二元线性回归和函数拟合,结果表明:震源断层平均错路与宽频带体波震级存在着确定的线性关系;而断层长度、面积、地震矩和应力降等仅在一定条件下才与震级有比例关系。更多还原

【Abstract】 On the basis of the focal theory of the dislocation model and using focal parameter of 18 earthquakes occurred in Yunnan (5.27≥mb≥6.09) and 40 other moderate and strong shocks (6.2≥mpv≥7.6) occurred outside China, the paper makes monadic and dualitic linear regressions and functional fitting of earthquake magnitude in relation to the focal parameters, the result of which shows the following: 1 ) Fixed linear relation exists between the average dislocation of the focal faults and the wide band body wave magnitude mb;2) Fault length, area, seismic moment and stress drop have propotional relations with earthquake magnitude only under specific conditions.更多还原
