Quiet Eruptions
Quiet eruptions are caused by smoothly streaming magma. This magma can have a lava flow than runs many kilometers away from the vent. One difference between quiet and explosive eruptions is the way gases dissolved in the different magma types are released. In the case of a quiet eruption, the thin and flowing magma allows the gases to be freed without a problem.
Pahoehoe is one of the two types of lava that quiet eruptions produce. Wrinkles, billows, and ropelike coils form on the surface of this fast-moving and hot lava. Aa is a more sluggish and a cooler lava. A rigid, pointy, and rough rock is created by this lava after it hardens.
Explosive Eruption
Explosive eruptions occur because of the type of magma in the volcano. Thick and sticky magma blocks the pipe of the volcano as the pressure builds up. Since pipe is clogged, the dissolved gases in the magma cannot escape as readily as in quiet explosions.The pressure continues to mount until the eagerly exploding gases force a massive explosion. The lava from this explosion separates into chunks and hardens from the intense blast, creating volcanic ash, cinders, and bombs. Pryoclastic flow, the mixture of volcanic ash, cinders, bombs, and gases, also comes from explosive eruptions.
