Although volcanic eruptions pose considerable hazards to humans, past volcanic activity has created important economic resources. Tuff formed from volcanic ash is a relatively soft rock, and it has been used for construction since ancient times.<ref name="marcari-etal-2007">Marcari, G., G. Fabbrocino, and G. Manfredi.

Volcanic ash and weathered basalt produce some of the most fertile soil in the world, rich in nutrients such as iron, magnesium, potassium, calcium, and phosphorus.<ref name="kiprop-2019">{{cite web|last1=Kiprop|first1=Joseph|date=January 18, 2019|title=Why Is Volcanic Soil Fertile?|url=https://www.worldatlas.com/articles/why-is-volcanic-soil-fertile.html|access-date=November 27, 2020|website=WorldAtlas.com}}</ref> Volcanic activity is responsible for emplacing valuable mineral resources, such as metal ores.<ref name="kiprop-2019" /> It is accompanied by high rates of heat flow from Earth's interior.
