Don't count on rainfall to bring those numbers down - it only receives a maximum 200mm every year. Worse, it is also one of the lowest places on Earth - at 410 ft (125m) below sea level.

These springs release chemical compounds like ferrous chloride and iron hydroxide that solidify when they come into contact with the atmosphere, painting the salt deposits and lakes in bizarre shades of green, yellow and white. What little reserves of water can be found are unsafe for human consumption - the waters are toxic.

The volcano is fed by at least two active lava lakes beneath the surface, one of which has been bubbling over since the mid-1960s, according to the Smithsonian Institution.
