Extreme rainfall hit the southern coast of South Korea this week, causing flooding and a building collapse in Busan [1].
The storm has saturated the ground across the Namhae area, raising the risk of further structural failures and landslides if the rain continues [1].
Over a three-day period, the region recorded a total of 483 mm of rain [1]. The intensity was particularly severe in the Gangseo-gu district, where maximum hourly rainfall exceeded 100 mm [1].
In Daedapo, Busan, the deluge left several shops water-logged and caused the roof of a fishing-gear store to collapse [1]. Local authorities said that no one was injured in the collapse, but the damage to local businesses remains significant [1].
The heavy rain affected several coastal areas beyond Busan, including Geoje and Tongyeong [1]. The sudden volume of water overwhelmed local drainage systems, leading to the widespread flooding of commercial properties [1].
Reporter Kim Geun-woo said that while there were no injuries, there are concerns about additional damage to older buildings as the rain persists [1].
Officials said that the saturated soil makes the region vulnerable to further incidents [1]. Residents in the southern coastal zones remain on alert as weather patterns continue to bring heavy precipitation to the peninsula [1].
“Total rainfall over three days reached 483 mm [1].”
The concentration of nearly 500 mm of rain over just three days highlights the increasing volatility of weather patterns on the Korean peninsula. When hourly rainfall exceeds 100 mm, urban drainage systems often reach capacity, transforming commercial districts into flood zones and placing extreme stress on aging infrastructure, as seen with the roof collapse in Daedapo.
