Abstract 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.
Key words ：
ultra-broadband seismometer
Wenchuan earthquake
