1936年夏在马边县玛脑地区,相隔约20天内连续发生两次6.7级强烈地震。自1960年以来,已有不少单位和个人进行过不同程度的调查和研究,编著有相应的书籍和报告。历年来的研究,对两次强震的地点、震级、发震时间及烈度评定都基本是一致的。但由于两次地震相隔时间较近,又地处边远少数民族山区,交通不便,在时代的情况下,不可能作专门的调查。嗣后的工作虽然资料逐渐增多,但两次地震彼此相混,很难分开。资料记
In the summer of 1936, a magnitude 6.7 earthquake sustained two consecutive seasons within about 20 days in the Marin area of Mabian County. Since 1960, many units and individuals have conducted various degrees of investigation and research and compiled corresponding books and reports. The study over the years has basically the same assessment of the location, magnitude, occurrence time and intensity of the two strong earthquakes. However, due to the relatively close time interval between the two earthquakes and the remote ethnic minority mountainous areas, traffic inconveniences can not be investigated exclusively under the current circumstances. Although the subsequent work gradually increased data, but the two earthquakes mixed with each other, it is difficult to separate. Data record
