The most glaring negative effects of volcanoes are death and destruction, including loss of human life. While lava flows are dangerous to nearby structures and buildings, ashfall is deadly. According to Volcano World, if ash is heavy enough, it causes buildings to collapse. The ash slowly suffocates people by making breathing nearly impossible or aggravating respiratory problems. Another cause of death is pyroclastic flow, which is a combination of hot gas and ash.
