Mt. Pelee is not a very tall volcano, in fact it is an example of what is called a "lava dome". It had a big eruption in 1902 which wiped out most people in a town downslope.
During the eruption, a burning cloud of hot ash and gases swept into the town. A similar eruption is illustrated in this picture of an Alaskan volcano.
Survivors of this eruption included one man who was in an underground jail cell, as well as sailors who were off-shore and witnessed the destruction of the city from a distance. Comments by these eyewitnesses included the following:
- "The mountain was blown to pieces, there was no warning."
- "It was like a giant oil refinery."
- "There was hurled straight toward us a solid wall of flame. It sounded like a thousand cannon."
- "The wave of fire was on us and over us like a flash of lightning. It was like a hurricane of fire."
- "The town vanished before our eyes."
