古诗有:“山雨欲来风满楼。”任何一种自然现象发生之前,总是会有前兆的。地震也不例外,地震前,在一定地域内,会出现一些物理、化学方面的变化,动物(蛇、鱼、鼠等)也会出现各种异常反应。那么,鱼类和地震有什么关系呢?先看几例:1917年7月31日云南大关发生6.5级地震。地震前一个月,大关河中鱼类浮出水面。地震前数日,河水大涨,河鱼千万自跃上岸。1976 Ancient poems are: “Before the rain all over the wind. ” Before any kind of natural phenomenon, there will always be a precursor. Earthquakes are no exception. Before the earthquake, some physical and chemical changes occurred in a certain area. Various abnormal reactions also occurred in animals (snakes, fish, mice, etc.). So, what is the relationship between fish and earthquakes? Look at a few cases: July 31, 1917 Yunnan 6.5 earthquake occurred. One month before the earthquake, fish in the river mark surfaced. A few days before the earthquake, the river rose so much that the river fish leaped ashore. 1976
