中文摘要:
      1920年12月16日海原发生8.5级大震。在该年前期,冀、鲁、豫、晋、陕五省大旱。与大旱有关的副高,其边缘引张环作用于旱区西边,对海原大震有中短期促发作用。临震前有西伯利亚寒潮传出的脉动触发了该大震,待寒潮大风来到震区时已在震后一天。这对灾民也是一种附加灾害。
英文摘要:
      The Haiyuan M8.5 earthquake occurred on December 16, 1920. Hebei, Shandong, Henan, Shanxi, and Shaanxi provinces suffered severe drought in the early 1920, and the subtropical high, which was related to the great drought, affected the western part of the drought area and had a short-and medium-term promoting effect on the Haiyuan earthquake. The microtremor generated by the Siberian cold wave prior to the earthquake was also related to Haiyuan earthquake, and the cold wave arrived in the earthquake area one day after the earthquake occurred, thus causing additional problems for the victims.
