What is the name of the volcano in Martinique?
La Soufrière de Guadeloupe is an active volcanic eruption that has seen many igneous and subterranean eruptions in the past.
The dangerous Martinique volcano only erupts once every two centuries on average. Mount Pelée, peaceful most of the time, experiences violent eruptions, especially of the Pelean type. The most dangerous active volcano in France is Mount Pelee on the island of Martinique.
There are two main types of volcanic eruptions depending on the type of magma emitted: effusive ones associated with “red volcanoes” and explosive ones associated with “grey volcanoes”. Effusive eruptions are Hawaiian and Strombolian eruptions, while explosive are Volcano, Pelean, and Plinian.
Geology and volcanology The fight against volcanic dynamism is characterized by explosive eruptions, rare but violent eruptions: the andesite contained in the depths of the volcano is a lava with a high silica content, very viscous, barely forming lava flows.

What is a subduction type volcano?
It is a volcanism with calcalcaline geochemistry. Subduction volcanoes generally line up parallel to the subduction zone, about 200 km from the oceanic trench. These alignments of volcanoes are called “volcanic arcs”.
Subduction is the process of sinking a tectonic plate under another plate of lower density, usually an oceanic plate under a continental plate or under a newer oceanic plate.
Subduction zones have intense seismic and volcanic activity, they are classified as active margins. The earthquakes delimit the limits of the plates and make it possible to visualize the subduction according to the Wadati-Bénioff plan. The characteristic subduction volcanism is explosive.
What are the different types of volcanoes?
- Strombolian eruptions, also called “Strombolian-like eruptions”;
- Volcanic eruptions, also known as “volcanic-type eruptions”;
- Pliny-like eruptions, also called “Pliny-like eruptions”;
- Pelean eruptions, also called “Pelean type eruptions”;
