人类对地震的认识最早始于我国.东汉的张衡在公元132年研制了世界上第一架地震仪——候风地动仪.他的基本思想是:地震是由远处一定方向传来的地面震动.这是一个本质性的理解,被公认为是地震科学发展的里程碑.直到18、19世纪,西方的一些人才重新确认这个概念.地震学诞生后,一直沿两个方向发展:一是研究地震——研究地震的成因和地震预报;二是利用地震——利用地震产生的地震波去探测地球内部.从科学史上看,前者开始得早,但进展缓慢.而本世纪以来,后者即利用人工方法产生地震波,再接收它们在岩层分界面产生的反射
The earliest human understanding of earthquakes started in our country, and Zhang Heng, from the Eastern Han Dynasty, developed the first seismograph in the world, the seismograph, in AD 132. His basic idea is that earthquakes are ground vibrations coming from a certain distance in the distance This is an essential understanding and is acknowledged as a milestone in the development of earthquake science.Throughout the 18th and 19th centuries, some people in the West reconfirmed this concept.After the birth of seismology, it has been developing in two directions: one is to study earthquakes - to study the causes of earthquakes and earthquake prediction; the second is the use of earthquakes - the use of seismic waves generated by earthquakes to detect the Earth’s interior. From a scientific history point of view, the former started early, but progress is slow, and this century, the latter that the use of artificial The method generates seismic waves and receives their reflections at the formation interface
