Live seismic activity in South Korea — updated every 60 seconds from USGS data. South Korea experiences periodic earthquakes, mainly in the southeastern Gyeongju region.
South Korea experiences periodic earthquakes, mainly in the southeastern Gyeongju region. The 2016 Gyeongju earthquake (M5.8) was the largest in South Korea in decades. Major faults include Yangsan Fault, Ulsan Fault. Notable quakes include 2016 Gyeongju (M5.8), 2017 Pohang (M5.4). The seismic risk is low to moderate. Tectonically, South Korea lies on intraplate – far from active plate boundaries. This page provides real‑time USGS data and historical context for South Korea.
The region is defined by Yangsan Fault, Ulsan Fault, and the risk level is classified as Low to Moderate. With a population of 51 million, understanding local seismic hazards is crucial.
South Korea lies on Intraplate – far from active plate boundaries. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.
The strongest recorded earthquake in South Korea was the 2016 Gyeongju earthquake (M5.8). 2016 Gyeongju (M5.8)
South Korea experiences low to moderate seismic activity, with occasional felt earthquakes, according to USGS historical data.
The most recent major earthquake in South Korea was the 2016 Gyeongju earthquake (M5.8). 2016 Gyeongju (M5.8)
Yes. South Korea is crossed by Yangsan Fault, Ulsan Fault, making it prone to seismic activity. The seismic risk level is classified as Low to Moderate.
Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
