近年来经常看到城市和大型企业发生重大火灾的报道:转瞬间一条居民街,一个工业设施被焚于火灾,其损失之大令人惊惧。考察古今火灾的酿成,除人为因素外,更可能是天然条件所酿成。天然火灾原因自然很多,火山,地震,星陨,雷电等等,但是更多的,作者认为是和地质环境有关系,是一定地质条件下溢出的天然气在作怪。从报道的重大火灾看,其特点就是火势燃烧的迅速,转瞬间就烧起一条街,几乎是同时起火,根本无法相救,火势甚至会越过城墙和壕堑,越过水面把湖泊中岛上的树木也烧着了,这除了天然气在作怪,任何人为的条件都难以形成这种情景。
In recent years, there have been reports of major fires in cities and large enterprises. Suddenly a residential street, an industrial facility was set in fire and its loss was alarming. Investigate the formation of ancient and modern fires, in addition to human factors, but more likely to be caused by natural conditions. There are many natural causes of fire, such as volcanoes, earthquakes, galactic meteorites, lightning bolts and so on. But more, the author thinks it is related to the geological environment and is a natural gas overflowing under certain geological conditions. From the reported major fires, it is characterized by the rapid burning of the fire, burning a street in a flash, almost simultaneously catching fire and simply unable to save the fire. The fire even crossed the walls and ditches and crossed the water to the trees in the lake Also burned, which in addition to natural gas at play, any artificial conditions are difficult to form such a scenario.
