Update 06:28 UTC: The white bullets on the map below show the previous earthquakes in the region since 1900. Last years earthquake below Gyeonju was about the same strength than today's one M5.3 vs M5.4 today.

Update 06:25 UTC: The earthquake was felt all over South Korea and probably also in the southern parts of North Korea.

Update 06:18 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, does expect at least some slight damage like cracks in walls, fallen tiles, etc.
