According to the map above Korea is in a safe zone away from a Convergent Plate Boundary. It is also apart of the Eurasian Plate and while it may seem like it from maps Korea is in fact not a part of the Ring of Fire. Meaning that Korea does not have much seismic activity and few volcanoes. In fact Korea only has four Holocene volcanoes, meaning that the volcanoes have been active for the last 11,700 years. The four volcanoes are called Ch'uga-ryong, Halla, Ulreung, and Baekdu Mountain. And there has been minimal activity from them. The last time any activity was recorded was in 1903 from the largest of the volcanoes that being Mt. Baekdu. Alongside this there has only been 20 earthquakes per year since 1978 in Korea, and most of these earthquakes have been 2.0 to 5.0, which is not considered very high. The highest magnitude of earthquake recorded was a 5.8 in 2016 called the Gyengju earthquake. The most recent earthquake was recorded in 2017 called the Pohang earthquake and was recorded as a 5.4 magnitude earthquake. In conclusion Korea is pretty safe from most disasters involving tectonic plates thanks to its position outside of the ring of fire and in a safe zone away from any converging, diverging, or transforming plate boundaries.
