Abstract The disadvantages of seismic alarm only based on the amplitude of seismic wave are analyzed.Through the comparison between the alarm mechanisms with digital and analog seismographs,the method for seismic alarm with the method of detecting both the period and amplitude is proposed.
Key words :
digital seismograph
seismic alarm
period
amplitude
earthquake
