Abstract

The research in seismic ambient noise as a tool for geophysical studies must primarily rely on the space-time characteristics of the noise itself. What is important in this research is to characterize the distribution of noise sources both over frequency and in energy content. The present review considers the main mechanisms for the generation of microseisms, including primary and secondary microseisms (0.05–0.3 Hz), low frequency oscillations (0.2–50 mHz), high frequency oscillations (2–60 Hz), and lake-generated microseisms (0.5–2 Hz). We also describe the most popular procedures in use for the processing and analysis of continuous seismic ambient noise arrivals; we demonstrate a wide range of geophysical problems based on recordings of microseismic ground motion.

微震作为地球物理研究的工具。回顾

摘要

作为地球物理研究工具的地震环境噪声研究，必须首先依赖于噪声本身的时空特征。在这项研究中重要的是表征噪声源在频率和能量含量上的分布。本综述考虑了微震产生的主要机制，包括初级和次级微震（0.05-0.3 Hz）、低频振荡（0.2-50 mHz）、高频振荡（2-60 Hz）和湖泊产生的微震（0.5–2 赫兹）。我们还描述了用于处理和分析连续地震环境噪声到达的最流行的程序；我们根据微震地面运动的记录展示了广泛的地球物理问题。
