曹蕴键和《曹南地震灾变记》

曹蕴键（1882—1970），字铁如，原籍山东定陶县，寄居菏泽。清末与民国时期历任知县、秘书、文书等职。1952年6月，被聘为中央文史研究馆馆员。《曹南地震灾变记》详述了他在1937年菏泽大地震时的亲身经历、震后的应急自救措施，以及所见所闻。菏泽大震发生于抗日战争爆发后，战火已烧到河北南部、山东、江苏沿海地区，政府和民间均无力救灾，有关震情与灾情的资料严重缺失。《曹记》则可稍作弥补，堪称珍贵史料。

Cao Yunjian and Record of disaster of Caonan earthquake

Cao Yunjian (1882—1970), also called Tieru, a native of Dingtao County, Shandong Province, lived in Heze. In the late Qing Dynasty and the Republic of China, he served as county magistrate, secretary and clerical official. In June 1952, he was hired as a librarian of Central Research Institute of Culture and History. Record of disaster of Caonan earthquake details his personal experience during the great Heze earthquake of 1937, as well as his emergency and self-help measures after the earthquake, and what he saw and heard. Heze earthquake occurred after the outbreak of the war of resistance against Japan, the war had spread to the coastal areas of southern Hebei, Shandong and Jiangsu, and both the government and the people were unable to provide disaster relief. There is a serious lack of information about the earthquake and the disaster. Record of disaster of Caonan earthquake can make up for this, and can be called precious historical materials.
