Some airborne materials released by volcanoes are not gases at all, but great masses of tiny particles, called aerosols. Most gases will disperse into the atmosphere shortly after being released from the volcano, sometimes causing lingering detrimental side effects such as acid rain. Airborne ...
Volcanoes form as a result of shifting tectonic plates beneath the earth's surface. Explore the process of volcanic formation, discover the Ring of Fire, and examine the types of volcanoes found throughout the globe. From Cornfield to Volcano ...
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...
Although experts believe “the probability of a volcanic eruption is relatively low,” the relentless inflation and recent shaking of Italy's Campi Flegrei caldera raise questions for experts—and locals.
Cinder cones, also known as pyroclastic cones, are the smallest and the simplest type of volcano. They are the world's most common volcanic landform. As the name "cinder cone" suggests, they are cone-shaped hills made up of ejected igneous rocks known as "cinders". These small volcanoes ...
The rocks in the earth's crust are constantly being stressed by forces exerted on them by natural processes, such as the movement of the earth's lithospheric plates or the pressure built up by magma beneath a volcano. Rocks can either change shape or break in response. ...
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...
As with natural threats, man-made hazards are occurrences that have not existed, such as terrorism. Man-made disasters are examples of particular situations in which man-made threats have become a fact in an event.Complex EmergenciesSome disasters are caused by a combination of natural and man-...
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 ...
