在地震发生前的瞬间,大自然总会以各种方式向我们发出预警，最令人称奇的现象之一便是地震发生时鱼群的异常反应，这一神秘现象引起了科学家们的广泛关注，也让人们对大自然的神奇力量有了更深的认识。
中文： 地震，这个人类历史上屡次造成巨大灾难的自然现象，总是让人防不胜防，在地震来临之前，大自然似乎总会有所暗示，最引人注目的便是地震瞬间鱼群的异常行为——乱跳。
地震发生时,地壳的剧烈运动会导致水体中的压力发生变化，这种变化对水生生物来说是一种强烈的刺激，鱼群作为水生生物的代表，对这种刺激的反应尤为明显，在地震即将来临的瞬间，鱼群会突然变得异常活跃，纷纷跳出水面，甚至跳出鱼塘。
这种现象在地震学上被称为“鱼群效应”，科学家们通过研究发现，鱼群在地震前的异常行为可能与地壳运动产生的次声波有关，次声波是一种频率低于人类听觉范围的声波，它能够在水中传播很远，当地震发生时，地壳的剧烈运动会产生大量的次声波，这些次声波通过水体传播，对鱼群造成刺激，导致它们出现乱跳的现象。
英文： Earthquakes, this natural phenomenon that has caused immense disasters throughout human history, always seem to come without warning. However, before the earthquake strikes, nature seems to send us subtle hints. One of the most striking phenomena is the abnormal behavior of fish during the moment of an earthquake—suddenly jumping out of the water.
When an earthquake occurs, the intense movement of the earth's crust causes changes in the pressure within bodies of water, which is a strong stimulus for aquatic life. Fish, as representatives of aquatic organisms, react particularly明显 to this stimulus. In the moments leading up to an earthquake, fish suddenly become highly active, jumping out of the water even out of fish ponds.
This phenomenon in seismology is known as the "fish effect." Scientists have found that the abnormal behavior of fish before an earthquake may be related to the secondary sound waves produced by the intense movement of the earth's crust. Secondary sound waves are sound waves with frequencies below the range of human hearing, which can propagate far in water. When an earthquake occurs, the intense movement of the earth's crust generates a large amount of secondary sound waves, which propagate through the water and stimulate the fish, causing them to jump out of the water in a frenzy.
