"彩虹"台风对宽频带地震计记录的影响
Influence of"Rainbow" typhoon on the recordings of broadband seismometer
摘要
Abstract
Using the recordings of broadband seismometers in adjacent stations in Guangdong Province during the No.201522 typhoon, also including one week before and after it, the correlation of the velocity amplitude is studied. It shows that the velocity amplitude of recordings from the station near to the typhoon landing area is gradually turning from stronger to weaker and the linear correlation coefifcient of the velocity amplitude of adjacent stations is above 0.9; Further analysis shows that the amplitude ratio between two adjacent stations is going to be stable when the frequency band of the recordings is deifned from 0.1 Hz to 1 Hz. In conclusion, the inlfuence of the typhoon on seismic background noise is very obvious. The amplitude ratio between two adjacent stations is stable in the 1-10 s frequency range.关键词
