The Eifel region in Germany is geographically famous for its Maars, which are broad, low-relief volcanic craters. These were formed by phreatomagmatic eruptions (magma interacting with groundwater). Many of these circular depressions have since filled with water, creating a unique ...

Geothermal power is generated by tapping into subterranean hot water and steam found in volcanic regions. Magma close to the surface heats groundwater, which is then extracted through deep wells. This high-pressure steam is used to turn turbines and generate ...
Ojos del Salado, located on the border between Chile and Argentina, is the highest active volcano in the world, standing at 6,893 meters. While it hasn’t had a major eruption recently, it shows persistent signs of activity like fumaroles. It ...
A volcanic neck (or plug) is a landform created when magma solidifies within the central vent of an active volcano. Over millions of years, the surrounding softer ash and cinder cone are eroded away by wind and water, leaving behind ...
Pumice is a highly vesicular (porous) volcanic glass produced during explosive eruptions. It forms when gas-rich, frothy magma cools so rapidly that the gas bubbles remain trapped as holes within the rock. Because it is filled with air pockets, its ...
