关于1932年8月14日西藏林芝7(1/4)级地震的讨论
THE DISCUSSION ON LINZHI, TIBET, EARTHQUAKE ( M=7(1/4) ) OF AUG 14, 1932
【摘要】 西藏地震史料汇编记载1932年8月14日西藏林芝发生过一次X度地震.据仪测资料,同日只有12时(北京时)在缅甸境内发生一次7级中深源地震.二者相距300多公里.它们是二次地震还是一次地震呢?认真分析了仪测资料,并重新修定震中,确认该日只有一次7级地震,震中在缅甸境内.再通过对历史记载的仔细分析,认为林芝地区的破坏,评为Ⅷ度比较合适.从而可考虑林芝的破坏受缅甸影响的可能性比较大.而Ⅶ度的高烈度可以深震常有的远距离异常区给以解释.
