In August 2022, an unprecedented downpour, the heaviest in 115 years, hit Seoul's Gangnam-gu, Seocho-gu, and Dongjak-gu areas, with a rainfall rate of 141 mm per hour. This led to widespread damage, including the flooding of the Gangnam Station area and the complete submersion of stations on both the Line 2 and Shinbundang Line subways. Tragically, the disaster also resulted in the loss of eight lives, including a brother and sister who fell into a manhole while walking on a nearby street.
