South Korean forest fire risk rises three weeks before Chuseok

An analysis by the National Institute of Forest Science reveals that approximately 80% of forest fires caused by grave visitors occur between three weeks before Chuseok and during the Chuseok holiday period. Based on 182 incidents recorded between 2011 and 2025, the highest frequency of fires was observed 14 to 21 days before Chuseok.

The increased risk during this period is attributed to early visits for grave maintenance (beolcho). Data shows that the probability of forest fires increases in areas with high cemetery density and in locations close to graves. High-risk areas where the probability exceeds 0.5 include Andong in Gyeongsangbuk-do, Hapcheon in Gyeongsangnam-do, and Pocheon in Gyeonggi-do.

Authorities remind the public that using fire or bringing incendiary devices into forests or adjacent areas is prohibited under the Forest Disaster Prevention Act. Violations can result in fines of up to 2 million won, while negligent fires that endanger the public can lead to up to five years in prison or fines up to 50 million won.
