What are the Hazards of Volcanoes? When a volcano erupts, there are a number of hazards that result from the event. First, the level of destruction in the immediate area of the volcano can be significant depending on the amount of lava and ash that results from the eruption. The ash can...

Seldovia is 80 miles from the volcano, on the far side of Cook Inlet. Two eruptions are captured in the photos, the first at 11:20 pm on March 27, and the second two hours later. The camera, a Canon Digital Rebel XTi with a Canon 70-200mm L lens, was only barely able to ...
Landslides, rock-slides, avalanches, slumps are widespread after the shaking of the ground. These are the secondary hazards that trigger after the earthquake. Landslides caused by the slope failure are triggered by a strong movement that occurs under the ground and causes damage to infrastructure an...
The target of this study is the Fogo Island in Cape Verde, where the hazards (caldera and/or flank collapse) and the timing (120 ka or younger?) are still controversial. Using high-resolution DEM, field geological and structural analysis, and high-precision K-Ar dating, we produced an ...
