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 ...
Craters and calderas are depressions formed by volcanic activity. A crater is a funnel-shaped vent at the top of a volcano formed by eruptions. A caldera is a much larger, basin-shaped depression created when a volcano’s summit collapses inward following ...
Pyroclast (from the Greek words for “fire” and “broken”) is the collective term for all fragmented material ejected by a volcano. This includes everything from fine volcanic ash and dust to medium-sized Lapilli and large volcanic bombs or blocks torn ...
While water vapor makes up the majority (up to 90%) of volcanic gases, the remaining significant components are Sulfur dioxide (SO2), Carbon dioxide (CO2) and Nitrogen (N2). Smaller amounts of hydrogen sulfide and carbon monoxide are also common. These gases ...
