Volcanologist Tom Pfeiffer explores some of Indonesia's most remote volcanoes.
The ancient Aztec legend of Popocatépetl.
In Indonesia, the air is 40 times above safe levels for humans and sulphuric acid vents from the ground in dense, yellow clouds; small volcanoes are reported to erupt every 15 minutes.
Japan is home to two of the top five most dangerous volcanoes on the planet.
For people who live on active volcanoes, life has an element of impermanence to it.
