有关1626年北京王恭厂奇灾的起因,众说纷纭,笔者主张地震说。这不仅因为事件同时有地震记事,而且事件发生前后有一系列地震迹象。这些迹象包括地震时间进程和空间分布两大方面,充分表明引起王恭厂火药库爆炸的地震具备一般天然地震应有的特征。北京地区是华北地震多发地区之一。史料证明,十六世纪末叶以后,地震频度加剧,震级猛增。发生在北京和影响北京的地震较大者就有:1597年10月6日渤海湾7 1/2级地震,1626年6月28日山西灵丘7级地震,1665年4月16日北京通县6 1/2级地震,1679年9月2日河北三河—北京平谷间八级地震,1720年7月12日河北沙城6 3/4级地震,1730年9月30日北京西 On the 1626 Beijing Wang Gong plant disaster caused by different opinions, I advocate the earthquake said.

Beijing is one of the most frequent areas in North China. Historical data show that after the end of the sixteenth century, the frequency of earthquakes intensified and the magnitude of earthquakes soared. The larger earthquakes that occurred in Beijing and Beijing were: the 7 1/2 Earthquake in Bohai Bay on October 6, 1597, the 7-magnitude earthquake in Lingqiu, Shanxi on June 28, 1626, and the April 16, 1616 Beijing-Beijing Earthquake County 6 1/2 Earthquake, September 2, 1679 Hebei Sanhe - Beijing Pinggu M8 Earthquake, July 12, 1720 Shacheng Hebei 6 3/4 Earthquake, September 30, 1730 Beijing West
