ANALYSIS TO THE SEISMIC WAVE FROM TIANCHI VOLCANO IN CHANGBAISHAN MOUNTAIN
-
摘要: 长白山天池火山是最具潜在喷发危险的火山,地震监测是有效的火山监测手段之一。小波分析是一门新兴学科,被称为"数字显微镜",它在时频两域具有良好的局部特性。本文对火山区不同种类的地震波形运用小波分析和频谱分析的方法,希望能提取不同类型火山地震的一些频谱特征,确定火山地震的类型。Abstract: Seismic monitoring is one of the effective means for volcano surveillance,especially for Changbaishan Tianchi Volcano,which is at stake of erupt.As a new study,Wavelet analysis is called "the digital microscope" and applied well in time and frequency field.Here we used Wavelet and spectral analysis to different kind seismic waves in volcanic area,in order to pick up their spectral character and determine the type of these earthquakes.
