PURPOSE: A seismic monitoring system is provided to rapidly confirm and measure an earthquake to precisely predict damages due to the earthquake for coping effectively with the tense situation and store the seismic wave data semi-permanently for future investigation. CONSTITUTION: A seismic monitoring system includes a seismic wave monitoring unit for sensing generation of seismic and measuring the movement of ground by acceleration unit, and a seismic wave receiving part for analyzing the acceleration data of the ground, filtering seismic components of natural frequency band at which a supply maintenance office is weakest, performing a vector synthesizing of a horizontal two components(south and north, east and west) and a vertical one component to compute a maximum ground acceleration, determining whether the movement of the ground is an earthquake or a simple impact, analyzing seismic response characteristics and comparing a state of a gas supply management office with a preset value if the movement is determined to be the earthquake, and storing the data and transmitting a seismic alarm, the maximum ground acceleration and a spectrum intensity to a control part.
