【摘要】 本文从震级—频度 LogN=a-bM 和累积频度关系 LogN_c=a_c-b_cM 得出小地震区可能发生的最大地震强度M_max=a_c/b_c+（1/b_c）Log（b_cL_n10）-（1/2b_c）Log（1+b_cL_n10）。以此研究了26个地震区（其中欧洲17个,川滇9个）的最大地震强度,与观测资料基本符合。比较各作者用于欧洲17个区的不同方法,结果大体一致,但本文的结果与观测资料更为接近。在一般情况下,M（max）≈a_o/b_c,当 b_c 值很低时,这一估计偏高。对结果进行了讨论。更多还原

【Abstract】 In the light of the magnitude-frequency relation. Log N=a-bM and the relation showing the cumulative frequency. Log Nc =ac-bcM, the probable maximum earthquake strength in a small region is obtained in the paper:Mmax=ac/bc+1/bc Log (bcLn10)-1/2bc Log ( 1+bcLn10).On the basis of the above formula, the maximum earthquake strength of 26 earthquake regions (17 of which in Europe, 9 in Sichuan and Yunnan, China) is calculated. The result from the study agrees essentially with the observational data. A comparison is made among the methods by different authors to the 17 earthquake regions in Europe, the result from which shows approximate agreement. Yet the result from this paper is much closer to the observational data.Under common conditions, Mmax≈ac/bc, this estimation may appear somewhathigher when the bc value is extremely low. Finally, a discussion is made on this result.更多还原
