Ol Doinyo Lengai volcano showing signs it may erupt
A volcano in northeastern Tanzania is showing signs it may erupt.

The Ol Doinyo Lengai - called as the 'Mountain of God' by the Masai people - is the only known active volcano with a type of lava that can move faster than a person.

It's now threatening nearby villages and three major sites of early human development.
