What is pelean lava?

Pelean lava is a type of volcanic lava that is characterized by its highly viscous and thick consistency, which results in the formation of steep-sided lava domes or volcanic plugs. Named after the 1902 eruption of Mount Pelée in Martinique, where this type of lava was prominently observed, Pelean lava typically flows slowly and can build up pressure, leading to explosive eruptions. Its high silica content contributes to its stickiness, making it distinct from other types of lava, such as basaltic lava, which flows more easily.
