H istorial South Korea Earthquakes In the past, South Korea used to have serious earthquakes that impacted its history. For instance, South Korea had a range of magnitudes between 6.7-7.5 in its own history. These higher/ powerful magnitude of the earthquakes include : Gyeongju which was approximately 6.7-7.0 magnitude in 779 ; In 1518 in Seoul there was an approximately 6.7 magnitude ; In 1643, Ulsan approximately  6.7-7.4 magnitude ; and  in Yangyang , approximately 7.5 in 1681. Fortunately, South Korea has lowered to a 6 magnitude since 1978. Also, South Korean earthquakes are always equal or stronger than magnitude 5.0. [   1978 and later Earthquakes in South Korea  ] South Korea Magnitude There are plenty of earthquakes in South Korea that are lower than 5.0 magnitude in the area, but some of them have equal or higher than a 5.0 magnitude ( lower than 6.0 magnitude).
