"Authorities explain that sinkholes occur due to improper construction or aging sewage and water pipes"
With more and sewage and water pipes aging I suspect this danger to become a lot bigger.. and not just here in Korea but in many different countries around the world. |

| What is scary is that nearly 48 percent, or about 5,023 km, of sewer pipes in Seoul are more than 30 years old. An inspection last year by the Environment Ministry of 1,637 km of sewer pipes 20 years or older throughout the country found one vulnerable spot per kilometer. |
So, of the 1637km they inspected...they found 1637 vulnerable spots.
If that isn't bad enough...apply that formula to rest of the uninspected pipes...make 5023 vulnerable spots.
Check this out...and times it by 5000...ouch!
