Full Answer

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. Pyroclastic flows are too fast to outrun, and they are so hot and cloying that they kill people and animals instantly.

While the negative effects of volcanoes are very serious, there are also some very positive effects. For one, the lava and ash are rich in nutrients. According to the BBC, they break down into the soil and make very fertile farmland. Volcanoes are also good sources of geothermal energy, provided a structure is in place to capture it. Finally, volcanoes create remarkable scenery that is great for tourism.
