1983年11月7日,山东省菏泽市与东明县交界处发生一次中强地震。据我国地震台网测定:微观震中在北纬35°14′,东经115°17′。面波震级5.9级,震源深度12公里。 地震发生在新构造活动强烈的聊考深断裂带南段的菏泽地区。1937年8月1日曾在菏泽发生过两次7级左右地震,这次地震的极震区与1937年地震的极震区完全重合。宏观考察结果确定:这次地震宏观震中位置在菏泽市马岭岗公社与东明县胡庄公社之
November 7, 1983, Shandong Heze City and Dongming County at the junction of a moderate earthquake. According to China’s seismological network determination: the micro-epicenter is 35 ° 14 ’north latitude and 115 ° 17’ east longitude. Surface wave magnitude 5.9, focal depth 12 km. The earthquake occurred in the Heze area where the new tectonism strongly interacts with the Heze area in the southern segment of the deep fault zone. On August 1, 1937, there were two earthquakes of magnitude 7 or so in Heze, and the extremely seismic zone of this earthquake completely coincided with the extremely seismic zone of the 1937 earthquake. Macro-survey results to determine: the macro epicenter of the earthquake in Heze City Maling Gang commune and Dongming County Huzhuang commune
