Mini-doc on the phenomenon of super-jangma; that is, extreme monsoon weather in Korea. Jangma flooding is always somewhat dangerous, and every year there is flooding severe enough to cause injuries and death.
But several years ago, Korea experienced a "keun-bi ", in which over 600 ml. of rain fell in 24 hours (annually Korea receives on average approximately 800 ml.). The result was catastrophic, and the black and white photos in this video are from a magazine article I wrote about some of the damage in our district.
At that time, mudslides destroyed apartments. The municipal government has is continuing to upgrade flood breaks and storm sewers--just as well since climate change seems to be a factor in this weather trend.
