![]() It gives us complete digital data and it works automatically. This records both velocity and accelerations of earth. This network was designed to provide an automated solution of seismic event for immediate response to tsunamigenic earthquakes. The new network of seismographs is composed of 12 broad-band seismometers, 28 short-period seismometers and 86 accelerometers. In 1997, KMA started a project for strengthening the national seismological observation network and the tsunami warning system. ![]() KMA has digital type seismographs with 45 local stations and 106 accelerometers. The highest magnitude recorded yet of an earthquake in the Korean Peninsula is 5.3, and it occurred in 1980. The average number of earthquake events has been about twenty per year since 1978, and generally the magnitude of these have not been so high, from 2.0 to 5.0 on the Richter scale. However, seismographs often record sudden occurrences of moderate events, and historical documents have recorded a few damaging earthquakes in this country, which show that Korean Peninsula is not totally a safe zone from earthquake disasters. The earthquake and tsunami monitoring section of the division carries out several jobs: monitoring seismic activities in the country, analyzing seismograms to calculate the earthquake source area and its magnitude, issuing timely seismic information, warnings about tsunamis, and developing seismic database (DB) with raw and event data.įortunately, earthquake activities in and around the peninsula are relatively low in number and intensity compared with the neighboring countries Japan and China. In order to mitigate earthquake and tsunami disasters, the division monitors seismic activities in and around the Korean Peninsula for 24 hours per day, and issues timely warnings and informations about them. The Earthquake Division of the National Meteorological Center in the KMA oversees these activities. KMA observes seismic and tidal phenomena, collects related data from its nationwide observation stations on a real-time basis, and analyzes the data using its comprehensive data processing systems. The Korea Meteorological Administration (KMA), as the government's meteorological organ, is responsible for issuing information on earthquakes and tsunamis.
