Based on the eruptive materials, volcanic hazards, and violence of eruptions, which type of volcano would be the most dangerous to live near? Cite specific hazards and how they could affect nearby residents

Answer: Composite cone volcanoes are considered the most dangerous volcanoes because of the violence of their eruptions and the numerous hazards they can generate. The lava associated with them tends to be andesitic or rhyolitic, which is stickier and results in pyroclastic eruptions. Pyroclastic flows can result in damage and death. Ash fall can result in damage and disrupted travel. Lahars can be problematic both during the eruption and long after the eruption is over, causing destruction and damage over long distances away from the volcano.
