The five pelean volcanoes are in the shape of domes and of the same family as the famous Gerbier de Jonc. Here are their names : the Montfol, the Sépoux, the Séponet, the Taupernas and the Lauzière.
A Peléan eruption is extrusive meaning it is caused by viscous, gas-poor magma which builds domes. Depending on the lava's viscosity, the domes can take on different shapes.
