A magnitude 3 earthquake rattled an area northeast of Yeoncheon, a border county in northern Gyeonggi Province, early Sunday morning, marking the strongest seismic event on the Korean Peninsula this year, according to the Korea Meteorological Administration.
The quake struck at 4:13 a.m., with its epicenter located 4 kilometers northeast of Yeoncheon at latitude 38.13 degrees north and longitude 127.1 degrees east. The tremor originated at a shallow depth of 9 kilometers, as detailed by the weather agency.
An image provided by the Korea Meteorological Administration and released via Yonhap news agency highlighted the precise location with a red dot in Yeoncheon, Gyeonggi Province, underscoring the proximity to this strategically sensitive border region.
This event stands out as the most powerful earthquake reported on the Korean Peninsula in 2026 so far. It is also the first tremor exceeding magnitude 3 detected both on the peninsula and in the surrounding waters this year.
Historical data from the Korea Meteorological Administration reveals seismic activity in the vicinity is not unprecedented. The last earthquake surpassing magnitude 3 within a 50-kilometer radius occurred on May 10 of the previous year, registering at magnitude 3.3 in the same area.
Since 1978, a total of 19 earthquakes have been recorded in the region, indicating a pattern of moderate seismic occurrences near Yeoncheon, though Sunday's event drew attention due to its intensity relative to recent years.
