Volcanoes

The spatial and temporal distribution of volcanism on Earth's surface is associated with geodynamics. Volcanic morphology is related to physical properties and chemical composition of the magma governed by the tectonic setting as well as exogenous processes over geological time. Eruptive activity comprises phenomena that are potentially dangerous to humans and infrastructure. The negative effects of those phenomena, however, can be minimized with hazard evaluation studies and volcanic monitoring. In contrast, eruptive activity has generated some of the most fertile soils of our planet, geothermal energy is produced from the internal heat of volcanic systems, volcanic materials have constructive and industrial uses, and volcanic landscapes are tourist sites.
