While the terms are distinct, the Vesuvian type (or Plinian) is often associated with the Pelean type in older geographical classifications due to their shared extreme explosiveness. Both involve high-viscosity magma and massive ash columns. However, modern geology usually treats ...

Vulcanian type volcanoes produce characteristic cauliflower-like ash clouds during eruptions. These eruptions are moderate to violent, involving the explosive release of gas and pulverized rock. The resulting clouds are dark, dense and turbulent, expanding outward as they rise into the ...
The Pelean type is the most explosive due to its extremely viscous magma. This thick lava often blocks the volcanic vent, creating immense pressure from trapped gases. When the pressure finally overcomes the blockage, it results in a massive explosion ...
