An earthquake of 5.8 magnitude occurred in Gyeongju on September 2016, and a 5.4 earthquake which is the second largest earthquake ever recorded also occurred in Pohang on November 2017. As the magnitude and frequency of earthquakes increase in Korea, unprecedented seismic damages, land creeping and liquefaction have been observed, and the perception that Korea is a safe zone for earthquake is changing. Recent characteristics of earthquake in Korea are shallow crustal earthquakes, which are difficult to predict and have a large vibration in comparison with seismic scale. We do not have a lot of experience in earthquake, so it is urgent to prepare countermeasures against earthquake-induced sediment disaster. In this study, we measured by the three point method on the slope of mountain where cracks and erosion occurred or possible occurred due to the earthquake occurred in Pohang, 2017. As a result of investigating surface fluctuation focusing on the cracks and stepped area occurring at the earthquake site, only a small erosion, sedimentation and area change were observed in most plots, but no significant correlation was found with a rainfall factor. However, if the above study continues and the data is accumulated, it is possible to identify the rainfall factors affecting the damage area by earthquake, and it can be useful to prepare the non-structural measures such as the landslide warning criteria in earthquake-prone area.
