First‚ we will discuss Mount St. Helens Volcano. Mount St. Helens is a stratovolcano located in the Pacific Northwest of the United States within Washington State. A stratovolcano is also known as a composite cone‚ which is “a large symmetrical structure that consists of alternating layers of explosively erupted cinders and ash interspersed with lava flows (Lutgens‚ 2012.)” Due to the cone shape of the volcano‚ stratovolcanoes are known for creating large explosive eruptions that can eject vast amounts

INTRODUCTION: The Ring of fire (figure 1) is a horse shoe shaped fault line. This fault line is prone to Earth quakes and volcanic eruptions. The ring of fire Is home to 452 volcanoes and 75% of the worlds dormant and active volcanoes live on the Ring. PLATE TECTONICS Plate tectonics is a theory that the earth is split up in to different areas of the world. They glide on the mantle of the earth the plates act like a hard ridged shell (fig 2 plate tectonics) Some of the plate tectonics move very

The Lava Pit One time in Hawaii‚ in 1888‚ there was a small village just next to a little beach.

The lava pit had always been filled with lava‚ and people wondered if it would ever erupt. For many years‚ tourists have visited Hawaii and come to see and take pictures of the lava pit. Unfortunately‚ many people

To what extent can planning and preparedness mitigate the effects of volcanic hazards? A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or environment. There is a very big difference that helps prepare for a volcanic hazard and that is whether you are in a MEDC or a LEDC. In a MEDC monitoring volcanic zones and potential hazards is an option many LEDC’s don’t have. In Italy at Mt Etna they have Geochemical monitoring programs currently run by INGV which focus on the

When people hear of Santorini‚ they think of the islands in Greece located in the beautiful waters of the Aegean sea.

Grímsvötn volcano is located near the center of the Vatnajökull ice cap in central Iceland. At a height of 5658 feet‚ it has the highest eruption frequency of all the volcanoes in Iceland. Grímsvötn volcano has a complex of calderas‚ of about six by eight kilometers in area‚ and a subglacial caldera lake sustained by geothermal heat. A caldera‚ a large‚ circular depression at the summit of a volcano‚ is formed when magma is withdrawn or erupted from a shallow underground magma reservoir. The caldera

You can hike‚ kayak‚ and canoe here. You can fish waist-deep in rivers as clear as glass. And you can watch the best fish catcher of all‚ the great Alaskan brown bear‚ sometimes diving completely under the water for its prey‚ sometimes catching fish in midair.
