On September 30, residents of Dangsan-ri, Songhae-myeon, Ganghwa County, Incheon, observed a loud boom and clouds of dust from a mountain on the North Korean side.
Residents of the village, located about 1.7㎞ from North Korea, said sounds believed to be blasting had continued since the summer.
Alongside the explosion sounds themselves, concerns are growing about daily safety in the border region and worsening inter-Korean relations.
3-Line Summary
1. Explosion sounds were heard in a border village on Ganghwa Island.
2. Residents reported hearing them 10~15 times a day.
3. Both the cause and safety measures need to be examined.
A Loud Boom from a Mountain on the North Korean Side, 1.7㎞ Away
According to a JoongAng Ilbo report, while waiting and watching toward a mountain on the North Korean side in Dangsan-ri, Songhae-myeon, Ganghwa County, on the afternoon of September 30, residents heard a loud “bang” at around 2:50 p.m., followed by dust rising into the air. The explosion sounds continued several times and subsided about 30 minutes later.
Dangsan-ri is a border village about 1.7㎞ from North Korea. Residents said sounds believed to be blasting related to construction noise from the North Korean side had continued since last summer. The village head said that after the explosion sounds began, a road that had not previously been visible appeared halfway up the mountain.
The exact purpose of the explosions cannot be confirmed based solely on residents’ testimony. However, the report said that North Korea had been intensifying so-called borderification work in the area around the Military Demarcation Line since 2024, including laying mines, clearing vegetation, building tactical roads, and installing barbed-wire fences. Yang Moo-jin, a distinguished professor at the University of North Korean Studies, expressed the view that the explosion sounds in the Ganghwa County area were also likely related to this work.
Anxiety Beyond What Residents Experienced as ‘Construction Noise’
Residents of Dangsan-ri complained that, since June, explosion sounds loud enough to make them feel their homes shake had occurred about 10~15 times a day. Repeated loud sounds can go beyond causing daily inconvenience and may be perceived by residents of border areas as a sign of renewed military tension.
The village also experienced the effects of noise from North Korean broadcasts directed at South Korea, which continued for about one year beginning in July 2024. According to reports, some residents complained of sleep disorders and stress, while some received hospital treatment. For this reason, concern about the latest explosion sounds does not end with a single loud noise.
The mine explosion accident in the Demilitarized Zone in Paju is another factor that has heightened residents’ anxiety. Based on the results of a joint on-site investigation, the United Nations Command determined on September 30 that the laying of North Korean antipersonnel mines discovered south of the Military Demarcation Line constituted a violation of the Armistice Agreement. The Joint Chiefs of Staff urged North Korea to halt its activities, apologize, and take responsible action.
Ganghwa’s Peace Projects Also Within the Reach of Inter-Korean Relations
The Kyongin Ilbo reported an analysis that the latest mine explosion could once again hamper Incheon City’s projects involving North Korea and peace initiatives. Incheon City has experienced the cancellation of exchange projects, including humanitarian assistance and an inter-Korean soccer tournament, as inter-Korean relations cooled following the Demilitarized Zone mine explosion in 2015.
Incheon City maintains that it is difficult to pursue inter-Korean exchange and cooperation projects at the local-government level unless an atmosphere of peace is established. Experts suggested that Incheon’s peace policy needs to be viewed through three pillars: exchange projects, peace discourse within the region, and the safety of residents in border areas.
The clearest standard that remains in this matter is this: rather than hastily determining the nature of the explosion sounds, it is necessary to examine whether actual safety measures are being put in place to reduce the noise and anxiety that residents repeatedly experience.
