摘要
对2005年1月18日乳山ML4.3地震序列特征及烈度分布进行了介绍,认为乳山ML4.3地震序列是一次能量衰减较快、频度起伏衰减的主-余型地震序列,序列本身不具有明显的前兆意义。
By introducing the characteristics and intensity distribution of Ru-Shan M_L4.3 earthquake sequence on January 18,2005,it is recognized that this sequence is a mainshock-aftershock sequence with rapid attenuation of energy,and fluctuation in frequency,the sequence itself has no precursory meaning.
