Research about noise variation around YUS station before and after the Yushu Earthquake

HAO Chun-yue,ZHENG Zhong,ZHANG Shuang (institute of Geophysics,China Earthquake administration,Beijing 100081,China)  
A earthquake occurred on Apr.14,2010 in Yushu county,Gansu Province in North China,the magnitude is MS 7.3.We researched the noise of Yushu station around the hypocenter of Yushu earthquake to see the variations of noise before and after the Yushu earthquake.We used two methods to research the noises,one is to research the RMS of the noises in several frequency bands, the other method is to research the noise spectrum during the one month before and after the Yushu earthquake.The research results told us that the noise of Yushu station had a higher noise level in 2009 than the level in 2008 in high frequency bands.The high frequency noise spectrum has minor increase relative to the noise model one month before Yushu Earthquake,has obvious increase half month before Yushu Earthquake,and has gradual decrease after a sharp increase after the earthquake.At last,the high frequency noise decrease gradually to a 2009 and even a 2008 model level,which lower than the noise level one month before Yushu Earthquake,seem to donate the fact that the high frequency noise increase before Yushu Earthquake have relationship with Yushu Earthquake,which is called the noise anomaly.
