A Lahar is a devastating volcanic hazard consisting of a mudflow of ash, rock debris and water. These flows occur when heavy rain, melting glaciers or displaced crater lakes mix with loose volcanic material. Lahars move at high speeds down ...

Fissure eruptions are most common at mid-oceanic ridges and continental plateaus. Instead of a central vent, magma emerges through long fractures or cracks in the crust. This occurs at divergent boundaries where plates pull apart, allowing low-viscosity basaltic lava to ...
Mount Kilimanjaro is classified as a dormant volcano. While it has not erupted in recorded history, its highest cone, Kibo, still emits volcanic gases, suggesting it could erupt again. In contrast, Mt. Fuji is also often considered dormant/active, but Kilimanjaro ...
The Pelean eruption type is geographically significant for producing pyroclastic flows, also known as Nuée Ardente (glowing clouds). These occur when highly viscous magma blocks the vent, leading to a build-up of gas that eventually explodes laterally. These high-speed, incandescent ...
Stromboli, located in the Aeolian Islands of Italy, is known as the “Lighthouse of the Mediterranean.” It has been in a state of nearly continuous eruption for over 2,000 years. Its regular, glowing bursts of lava are visible from long ...
