America’s national parks are more than areas of scenic or historical importance, these parks embody the idea of preserving what is left of this country’s beautiful wildlife, before mankind adapted and urbanized. Ernest Ortega, the Former Park Superintendent stated, “Parks belong to everyone. Parks belong to all of us. Our history is there. America’s history, as diverse as it is, is captured by the national parks (“This is America”).” National parks are there for everyone and with the times…

Loa, and Mauna Kea.Kohola is the oldest volcano on Hawaii Island at more than one million years old and Kilauea is the youngest at between 300,000 and 600,000 years old.Kilauea's summit caldera is large at 2 miles by 2 miles in size.…

Iceland is located in the North Atlantic sea, near the arctic circle. Iceland is 40,000 square miles large, which is approximately the size of Virginia and Kentucky combined. Only around 20 percent of the island is inhabited, and it is smallest country in Europe based on population (Geography). Some refer to the island as the land of fire and ice due to the presence of both glaciers and volcanoes (Gunnarsdóttir, Nanna, 2016). Volcanoes can even be found beneath glaciers. Glaciers cover more than…

The Earth is a birthplace for incredible natural disasters. These are earthquakes, tsunamis, and tornadoes to name just a few. But one disaster, famously known for its ability to spew hot magma from an opening in its surface is considered the most captivating. Volcanoes, whose name originates from Vulcan the Roman god of fire, are some of the most stunning and fascinating processes to occur underneath and on the surface of the earth. To better understand volcanoes this essay will touch on…

blast blew the mountains apart on the evening of April 10. The blast killed at least 10,000 islanders and destroyed the homes of 35,000 more. Before its eruption Mount Tambora was about 4,300 meters (14,000 feet) high. After the eruption ended, a caldera spanning some 6 km (3.7 miles) across remained. Many volcanologists regard the Mount Tambora eruption as the largest and most-destructive volcanic event in recorded history, expelling as much as 150 cubic km…

nature. Because of this, they have very large diameters, and gently rising slopes. Many shield volcanoes feature a caldera at their summit, which is a result of the underlying magma chamber empties and collapse. The rock between the summit and the now empty magma chamber it too heavy for the structure of the volcano, and collapses into the empty space. This collapse gives the caldera very steep walls. Towards the end of a shield volcanos life, the eruptions become more random and eject rock,…

entering into a utopia. Fira and Oia are the two more thought-provoking towns, and sure, you could take a short bus between these two towns, but you might miss out on some of the most unforgettable and breathtaking scenery in all of Europe. Walk the Caldera-top path and delight your senses with experiences of another world. Fira: What to Expect If you decide to blaze a trail during Santorini's low season, you will have a quieter experience as most of Fira and Oia will be deserted. The first…

The initial explosion decimated the Santorini islands, and the collapse of the caldera (along with the explosion of the island) created a massive tsunami, which reached the Eastern Mediterranean shorelines and easily overtook many surrounding islands and coastlines, including Crete. The estimated wave height was 35 to 150 meters, and…

ago Missouri was a landscape dominated by volcanic calderas some of those measured 15 miles in diameter. They closely resemble the caldera of Yellowstone which is dormant today and do not erupt from one main vent but instead erupts lava from multiple vents in a series of smaller eruptions. Sometimes the pressure can build up forming a crater, miles in diameter. The higher the silica content the more viscous or thick the lava. Rhyolite calderas produce the most violent eruptions of any type…

Trans-Pecos Province Magma Types Nathanial Matis 01/12/2014 Trans-Pecos Province Magma Types Nathanial Matis Abstract The Cretaceous was the starting point when the Laramide Orogeny began to fault and fold as a result of tectonic activity which pushed the Farallon plate into the North American plate forcing the subduction of the Farallon. This subduction caused the plate to melt and form magma that either formed laccoliths, or intruded country rock with different igneous compositions. These…
