【摘要】 清朝时期,从今甘肃地区看,地震前后震区或震区所在的祁秦吕贺构造带及其分支白银—靖远—海源—固原—平凉弧形构造带气象异常频次增加。气象异常类型有旱涝异常(周围大面积区域旱或大旱,中心风调雨顺、涝或大涝;周围大面积区域正常、涝或大涝,中心旱或大旱,旱、涝区走向与构造带一致)、气温异常(夏陨霜、夏大雪、夏冬暖)、生物异常(主要有秋冬重花、饥荒和疾疫等)、其他异常(如地震云、黑眚、地生白毛、黄河清澈见底、大风、雷鸣等)。地震前后,气象异常具有多发特征。更多还原

【Abstract】 In Qing Dynasty,meteorological disasters before and after earthquakes happened frequently at Qi-Qin-Lv-He seismic belt and its branches Baiyin-Jingyuan-Haiyuan-Guyuan-Pingliang tectonic belt of Gansu Province,which was concretely expressed in the following examples: drought and flood anomaly,drought in the surrounding areas while normal or flood in the center;normal climate or flood in the surrounding areas but drought in the center;the flood and drought areas were consistent with the direction of tectonic belt;temperature anomaly,such as frost,snow and rain in summer,but especially warm in winter;abnormal organism,for example,flowering in winter and autumn,famine and blight;other abnormal weathers,such as seimic cloud,drum,frequent thunderstorm,black buran,gale,thunder and so on,those abnormal weathers occurred frequently before and after earthquakes.更多还原
