But … Web3 mrt. 2024 · How do hotspot volcanoes form? Hotspots occur when one of the Earth’s plates moves over an unusually hot part of the Earth’s mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.
Web8 apr. 2024 · No, not at all. The general type of magma that produces runny lava flows is different to the types that produce those big explosive eruptions, and they do not erupt at the same time. Speaking of pyroclastic flows – the very hot, rapid avalanches of volcanic rock and gases, they are usually far too fast to outrun and far too hot to walk away from.
