Part of Hongdaeipgu Station on Subway Line No. 2 in Seoul was flooded as a result of a 10-minute torrential downpour on Wednesday night.
According to Seoul Metro, muddy water poured into the station around 10 p.m., temporarily blocking a couple of exits and some ticket turnstiles. Part of the station was flooded with 5 cm of rainwater and passengers had to roll up their pants or take off their shoes.
At the time, some 10 mm/h of rain fell in Seoul. A spokesman for Seoul Metro said trains ran without a hitch although rainwater flowed on the platform.
Around 10:20 p.m., officers from Seoul Metro and a nearby fire station began pumping out the water, while piling up sandbags to prevent more rainwater from pouring in. They brought the situation under control around 11 p.m.
Back in May, the Seoul city government took anti-flooding measures and launched a disaster control center to improve the response to such emergencies.
