法国国立天文和地球物理研究所(法文名称的缩写为 INAG)的地震学家们近来研制了一种能安装在海底的地震仪,并称之为“海底地震仪器”的进展。根据法国国立天文和地球物理研究所取得的成果,巴黎地球物理研究所成功地制造了七台海底地震仪。这些地震仪可以通过自由下落的方式安装在深度为1,000米以上的海底,并按照预先确定的程序进行有始有终的记录。工作结束后,在操作装置上除掉压载,地震仪就 Seismologists from the French National Institute of Astrophysics and Geophysics (INAG) have recently developed a seismograph that can be installed on the seabed and described it as a “seafloor seismic instrument”. Based on the achievements of the French National Institute of Astrophysics and Geophysics, the Paris Institute of Geophysics has successfully produced seven seabed seismographs. These seismometers can be mounted on the seafloor at a depth of 1,000 meters or more in a free-fall manner and have an end-of-record recording according to a predetermined procedure. After the work is finished, ballast and seismograph are removed from the operating device
