Abstract High frequency tremor wave were found in onesamplepersecond data observed by broadband tiltmeter, broadband seismometer and PET gravimeter. The analysis results of the data recorded in broadband titmeter and the meteorologic data during 2008—July 2011 indicate that the high frequency tremor wave(0.13-0.33 Hz)is related to typhoon and the sea wind with a speed of grade 6 or more, especially the sea wind in Taiwan Strait.
