Disaster Response in Port Areas Based on the Measured Data from Seismic Accelerometers

As of May 2023, the Ministry of Oceans and Fisheries (MOF) in Korea is operating a port alert system for seismic response at 28 stations centered on 13 trade ports to monitor the stability of the port structures rapidly after earthquakes. The peak ground acceleration according to measuring stations can be analyzed using the data processing algorithm. Based on this, we review the excess rate of the design acceleration for port structures during earthquakes and utilize them as an emergency safety check. It plays a significant role in operating intelligent situation management under earthquake disasters. This system makes it possible to make quick decisions and respond to earthquake disaster fields in ports. This paper overviews the smart disaster management system for ports in Korea, with priority given to the response stage. And it introduced the application of these measurement data processing algorithms.
