  • As part of preparing for future earthquakes near three LNG receiving terminals located in coastal regions of Korea, acceleration monitoring systems were installed at four free field sites and on a pile foundation beneath a storage tank in a receiving terminal. Several equipments and accessories were devised to successfully install and operate the monitoring system at LNG receiving terminals. Synthetic earthquake-alarming software systems designed for decisionmaking, based on peak ground acceleration computed using the measured data, were developed for rapid response during earthquakes, not only in each local terminal area but also in the central control division. In addition, a framework software linking nationwide data on peak ground accelerations was included in the integrated earthquake alarming system in the central division, for various future applications. The earthquake alarming systems developed in this research for LNG receiving terminals, based on acceleration monitoring, represent a useful framework for industrial facilities located in coastal regions, where geotechnical conditions may show marked spatial variations.
