Mount Pelée is a huge, active stratovolcano. It sits at the northern end of Martinique. This island is part of the Lesser Antilles Volcanic Arc. This arc is a long, curved chain of volcanoes.

The volcano is shaped like a cone. This cone is made of many layers. These layers are made of hardened ash and solidified lava. A stratovolcano like this forms in a subduction zone. This happens when one piece of the Earth's crust meets another. In this case, the Caribbean Plate meets the Atlantic oceanic crust. This movement creates the heat and pressure needed for volcanoes.

The volcano has changed many times over thousands of years. Scientists see three different stages in its history. The first stage was called the Paléo-Pelée stage. During this time, it was a common stratovolcano. The second stage began about 100,000 years ago. This stage saw the formation of the Morne Macouba lava dome. Around 25,000 years ago, a large part of the mountain collapsed. This created a massive landslide. The third stage is the modern stage. This stage created most of the cone we see today. It left behind deposits of pumice and ash.

Mount Pelée is famous for a very sad event in 1902. On May 8, 1902, the volcano had a massive eruption. This eruption destroyed the town of Saint-Pierre. It killed between 29,000 and 30,000 people in just a few minutes. This was the worst volcanic disaster of the 20th century. Only three people were known to survive the event. One man, Ludger Sylbaris, survived in a small, dark jail cell. A girl named Havivra Da Ifrile found safety in a sea cave. Another man named Léon Compère-Léandre escaped with bad burns.

Even though the big eruption was long ago, the volcano is still active. It erupted again from 1929 to 1932. In 1929, people were ready and evacuated the area. This helped keep people safe from the pyroclastic flows. These flows are fast-moving clouds of hot ash and gas. Today, scientists watch the volcano very closely. They look for small earthquakes that show magma is moving. In May 2025, researchers recorded 632 earthquakes in one month. These shakes mean the magma is moving deep underground. They do not mean an eruption is happening right now.

Many living things call Mount Pelée home. A special frog called the Martinique volcano frog lives only there. The mountain also has large forests that many birds love. You can find many types of birds like hummingbirds and orioles there. Because the area is so special, it is a UNESCO World Heritage site. This status helps protect the forests and the volcanoes. The mountain range covers 12% of the island of Martinique. It is a very important place for nature and science.
