甲:同志们,听我言, 我把地震谈一谈。 我们住的大地球, 形状象个大鸡蛋。 最外一层叫地壳, 平均厚度三十公里还要多。 地壳不断运动着, 倾斜褶皱又断裂。 地壳断裂或错动, 地面随着就震动。乙:噢！地动原是地壳动, 不是什么乌龟翻身地牛滚, 也不是老天要抓人。 地不陷,天不塌, 封建迷信别信它。 你说地球这么大, 大地震常常发生在那里呀?甲:地震分布不均匀, 但有规律可找寻。 海洋大陆交界处, A: Comrades, listen to me, I talk about the earthquake. The big earth we live in, shaped like a big egg. The outermost layer called the crust, the average thickness of more than thirty kilometers. The crust is constantly moving, tilted and creased. The crust is broken or dislocated and the ground vibrates with it. B: Oh! Ground movement is the crust, not what the turtle stand up to cow, nor is God want to arrest people. Earth does not fall, heaven does not collapse, feudal superstition do not believe it. You say that the earth is so big, where great earthquakes happen? A: The earthquake is unevenly distributed, but there are laws to look for. Marine continental junction,
