La Soufrière: Waiting for an Inevitable Catastrophe (1977)

Herzog heard that Guadeloupe had been evacuated ahead of a predicted eruption, learned that someone had refused to leave, and flew straight to the volcano with a camera crew. That decision is the whole film, and it tells you more about him than any interview. The deserted streets, the man who stayed to look after the animals and the one calmly waiting for death make for an eerie half hour. The volcano did not erupt, and the anticlimax is the point: a darkly funny study of how people face a catastrophe that never comes.
