ANOMALIES OBSERVED BY ULTRA BROADBAND SEISMOMETER BEFORE WENCHUAN EARTHQUAKE

Zhang Yan,Wu Yun,Lü Yongqing,Hu Jin and Lü Pinji(Institute of Seismology,CEA,Wuhan 430071)  
According to the observations of 16 ultra-broadband seismometers from 1st to 12th May 2008,it is demonstrated that there were obvious anomalies in 64-512 s ahead of the Wenchuan Ms8.0 earthquake in some frequency exclusively from the impact of the typhoon,this phenomena might be information related to the earthquake preparation.
