摘要
高精度重力观测是地震学研究的一个重要手段,近年来在中国地震预测预报工作中发挥了重要作用。首先简要介绍了重力观测仪器的发展现状与分类,然后从重力观测网规模、重力数据处理流程、重力观测结果解释等方面对中日两国的研究现状进行了对比,并在此基础上系统分析了中国地震重力观测研究面对的挑战,力争为后续工作提供一些借鉴与启示。
High precision gravity observation is an important tool of seismological research and has played an important role in earthquake prediction in China in recent years.This paper first briefly introduces the development status and classification of gravity observation instruments,then compares the seismic gravity observations and researches for seismic events between China and Japan from the aspects of the scale of the seismic gravity observation network,the gravity data processing process and the interpretation of gravity observation results,and finally systematically analyzes the challenges faced by the gravity observation research in China.The aim of this paper is to provide some reference and enlightenment for the follow-up work.
