Which volcano type is the most highly explosive?
Because they form in a system of underground conduits, stratovolcanoes may blow out the sides of the cone as well as the summit crater. Stratovolcanoes are considered the most violent. Mount St. Helens, in Washington state, is a stratovolcano that erupted on May 18, 1980.Click to see full answer. Similarly one may ask, which type…

Similarly one may ask, which type of volcano is the most explosive?Rhyolite caldera complexes are the most explosive of Earth’s volcanoes but often don’t even look like volcanoes. They are usually so explosive when they erupt that they end up collapsing in on themselves rather than building any tall structure (George Walker has termed such structures “inverse volcanoes”).Secondly, which volcanic centers tend to have the most explosive eruptions? Explanation: Lava domes have most explosive activity. Lava domes have the highest silicic magmas with pyroclastic material. Also, which type of magma is most explosive? Explosive eruptions are favored by high gas content and high viscosity (andesitic to rhyolitic magmas). Temperature of Magmas Basaltic magma – 1000 to 1200oC. Andesitic magma – 800 to 1000oC. Rhyolitic magma – 650 to 800oC. How does a volcano start?Volcanoes are formed when magma from within the Earth’s upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
