The damage caused by the recent earthquake in Gyeongju and Pohang highlights the need to develop countermeasures for mountainous sediment-disasters. Earthquake-induced ground-failure occurs due to inertial forces to the mountain and the subsequent rise of groundwater and pore water pressure. Although ground-failures are one of the main secondary effects triggered by earthquake, they have not yet been recorded in Korea and thus, the related research in the region is insufficient. In order to provide sufficient data for future countermeasures, we analyze the characteristics of ground-failure caused by 318 earthquakes around the world since the 1900’s based on the reviewed database of the U.S. Geological Survey (USGS). The percentage (the number) of earthquake-induce ground-failures was highest in Asia at 37% (120 times), followed by 19% (61 times) in South America and 13% (40 times) in the Middle East. The percentage (the number) of earthquake-induced ground-failures in Asia was highest in Japan at 32% (40 times), followed by 13% (16 times) in China, Taiwan and Indonesia, respectively. The magnitude of earthquake-induced ground-failures have gradually decreased since the 1900’s in Asia, Oceania, and North America. Although climate, soil and geological conditions vary between each country, earthquake-induced ground-failures typically occur when the magnitude of an earthquake is 5.0 or higher. Ground-failures are most common from earthquake between 6.5 and 7.0 magnitude and when the epicenter is located 10 to 20 km depth.
