ANALYSIS TO THE SEISMIC WAVE FROM TIANCHI VOLCANO IN CHANGBAISHAN MOUNTAIN

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.
