Explosive

• Strombolian


  one of the least violent explosive eruptions consisting of runny basaltic or basaltic-andesite lava spurted out of a magma-covered opening
• Vulcanian


  short but explosive eruption that ejects columns of ash and viscous lava bombs into the atmosphere.
• Plinian


  most violent explosive eruption, and the appearance of the explosion is often compared to the shape of a mushroom, similar to that of a nuclear bomb explosion.
• Hawaiian


  gentle spurts of liquid basaltic lava that shoot out from the vent like a lava fountain, or from the fissures on the flanks which create lava flow.
• Explosive Eruptions


  violent eruptions of viscous lava, solid debris, and hot gases that are ejected at supersonic speeds from the volcano's opening
