一地球物理学是以物理学的原則和方法来研究地球整体及其組成部分——地球本体、大气和海洋——的性貭、状态及在其中发生的自然現象的物理过程的一門科学。很早以前,自然現象就为人們所注意,我国古代科学家对于地球物理并有了不少的貢献。最早的地震历史記載可追溯到公元前1189年,或者更早。世界上第一架地震計在公元132年就已出現。汉代已发明測风向和雨量計。公元724年,僧一行等已測出子年綫一度的长度。在11世紀以前,中国人就已知道地磁偏角并发明航海指南針。明永乐年间(1424年) Geophysics is a science that uses the principles and methods of physics to study the physical processes, phenomena, states, and natural phenomena occurring in the Earth as a whole, as an integral part of the Earth’s body, the atmosphere, and the sea. Long ago, natural phenomena were noticed by people. Ancient Chinese scientists made a great contribution to geophysics. The earliest earthquake records date back to 1189 BC, or earlier. The first seismograph in the world appeared in 132 AD. Han Dynasty has invented the wind direction and the rain gauge. In 724 AD, monks and his party had measured the length of a sub-year line. Before the 11th century, Chinese people knew the declination of the earth’s magnetic pole and invented the nautical compass. Ming Yongle years (1424)
