The 2016 Gyeongju earthquake occurred on September 12, 2016 in Gyeongju, South Korea. It was a
M 5.8 earthquake, the strongest one ever recorded in the country since instrumental measurements
began in 1978. When the dams in Korea were shaken by the 2016 Gyeongju earthquake, seismic
motions of the dams were captured by accelerometers installed at many major dams in Korea by Korea
Water Resources Corporation (K-water). Fortunately, no severe damages were reported except only
longitudinal cracks found at crests of two earth dams for irrigation several kilometers away from the
epicenter.
In this paper, the characteristics of 2016 Gyeongju earthquake itself and seismic motions, in particular
accelerations, will be analyzed to introduce better understanding on seismic responses of dams
subjected to earthquake motions. Furthermore attenuation characteristics of measured accelerations
will be evaluated and compared to the previously suggested ones in Korea and other countries.
