How Volcanoes Work: Products of Eruptions

From DLESE Community Collection (DCC)
Comment on this resource
This site describes volcanic features and phenomena generated by volcanic eruptions. It discusses eruptive products, which are highly variable and largely dependent on the composition, viscosity, and gas content of the erupting magma. In addition to the general discussion on lava flows there are links to detailed discussions on lava flow types and features along with specific information on basaltic, andesite, dacite, and rhyolite lavas. Other links lead to information about pyroclastic flows and lahars. Gaseous emissions are also examined, as are their harmful effects on both local and global scales.
