Typhoons and Rainstorms
9.Basements are especially dangerous

Rule 6:
Basements are especially dangerous.

During a torrential rain in Fukuoka in June 1999, the basement of an office building was suddenly inundated and a worker was killed. A month later the same thing happened in a Tokyo building. Shopping malls and parking garages may also have underground levels. Although it may seem secure during our normal daily routine, any space below ground level can become a dangerous flood trap during a heavy storm.
