Kowloon Walled City | A population density nightmare

Kowloon Walled City was a largely ungoverned Chinese settlement in Kowloon, Hong Kong, comprising of 350 interconnected high-rise buildings where 33,000 residents lived within a plot measuring just 210 meter by 120 meter. Originally a Chinese military fort, the Walled City became an enclave after the New Territories were leased to Britain in 1898. Its population increased dramatically following the Japanese occupation of Hong Kong during World War II and reached a peak of 33,000 residents in 1987. When it was demolished in 1993-94, it was thought to be the most densely populated place on earth.

Dirty thunderstorms

A dirty thunderstorm (also, Volcanic lightning) is a weather phenomenon that occurs when lightning is produced in a volcanic plume. A study in the journal Science indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms.
