WebInstead, felsic eruptions of stratovolcanoes tend to be more explosive and are associated with the creation of tephra or pyroclastic flow. This begs the question: What type of volcano is andesite? Andesite is often found in stratovolcanoes-produced lava flows. These lavas were formed from small crystals because they cooled quickly at the surface. WebShield volcanoes have very gentle slopes of only a few percent that become even more gentle near the summit. The great width of these volcanoes relative to their height is the result of the low viscosities of erupted lavas that produce thin widespread lava flows, eruptions from both the summit and fissure vents on the volcano’s flanks, and widening … the pale blue eye kurdSeveral of the most-famous volcanic disasters in history resulted from the eruptions of stratovolcanoes.
