WebAlthough they are not as explosive as large silicic caldera complexes, strato volcanoes have caused by far the most casualties of any type of volcano. This is for many reasons. First is that there are so many more strato volcanoes than any of the other types.

WebMay 12, 2024 · These volcanoes can be hundreds of kilometers wide. Shield volcanoes tend to erupt fluid basalt lava. Violent explosions are possible. But they’re not as common for shield volcanoes. Because basalt has a low viscosity (more watery), it can flow on the surface better. When these types of volcanoes erupt, lava flows out large distances.
WebNov 10, 2024 · Over 60% of the world’s volcanoes are believed to be stratovolcanoes, which have steep sides, high summits, and can cause some pretty exciting eruptions. These volcanoes are mostly made of andesites and dacites, which are much more viscous types of lava than the basalt lavas found in shield volcanoes. cheapest atkins induction mealsNyiragongo is very dangerous because its magma has an unusually low silica content, making it quite fluid. Fluid lavas are typically associated with the formation of broad shield volcanoes such as those of Hawaii, but Nyiragongo has very steep slopes down which lava can flow at up to 100 km/h (60 mph).
