People have travelled across the entire globe searching for the city of Atlantis. They have dived into the deepest depths of the sea, and have climbed mountain ranges all in the pursuit of discovery. At least half a dozen expeditions are launched each year, and some explorers would swear they were successful. Professionals claim that the most likely location of Atlantis is a small island called Santorini which is off the coast of Greece. It would seem as though Plato described this exact place…

Would people recognize the difference between “active volcano” and “Holocene volcano?” Well there is no difference, people just use the term “active” wrong. Scientist say that, “...it is misleading to restrict “active volcano” to recorded human memories: we prefer to add another identifying word (“historically active” or “Holocene volcano”).” People are probably confused on what these terms actually mean because no one would see the difference or wouldn’t care. Volcanoes are very old, they…

In a modern global history class taught today, students learn all about the eruption of Mount Vesuvius in 79AD. They know the basic facts, such as how the cities of Pompeii and Herculaneum were covered with ash, how many, many people died because of the volcano eruption, and how the description we have of the eruption is from a letter written by Pliny the Younger (61AD-113AD). However, many students are not taught about what Roman life was like in Pompeii before the eruption of the volcano. The…

lasted 18-20 hours, and left huge amounts of volcanic ash and rock in the air, blanketing the sun and turning day into night. As the cloud collapsed, it triggered the second phase- the Peléan phase, where pyroclastic flows of andesite rock, and molten lava engulfed Pompeii, and Herculaneum. These cities were buried in fine ash, pumice, and pyroclastic deposits, while a toxic cloud of gas descended upon Pompeii (History.com staff, 2009). Around 2,000 died from the eruption, either from…

The Augustine volcano stands 1260 meters high casting a massive shadow within the Cook Inlet on its 82 square kilometer island(Aden)(59.36 N, 153.43 W). This Stratovolcano has large explosive eruptions that spew lava and ash. When Augustine erupts, the surrounding area of Cook Inlet and the surrounding area suffer the effects. While augustine has a repose time of twenty four years on average the state of Alaska and the immediate area have grown used to the eruptions…

The purpose of this paper is the explain a natural phenomena, Axial Seamount. Even if the reader has no knowledge of Axial Seamount, they will be able to fully understand the content of this paper. They will learn facts about Axial Seamount such as what it is, on what plates it is located on, what landforms are around it, etc. Axial Seamount is an underwater volcano located in the Northeastern Pacific Ocean, about 483 kilometers (300 miles) off the coast of Oregon. Because its frequent volcanic…

There are a total of ten different landscape regions located within the Pacific Northwest. The rocks that are within each region provide the foundation for the landscape within the region. The study of the rock located in the region tells us about the geologic past and provides insight on the materials and processes from which the landscape was formed. I will briefly discuss each of the areas and provide insight on the types of rocks in which they are formed from. We will start with the Basin…

This week I learned about the three different types of volcanoes and the types of volcanic hazards associated with each type of volcano. This information is important to me because now I understand the hazards associated with living in certain parts of the country that have volcanoes. I understand that the volcanoes found in Hawaii (Shield volcanoes) erupt differently and pose different dangers than the volcanoes in the Cascade Mountain Range (Composite volcanoes). Since I live in Portland,…

Kilimanjaro rises approximately 4,877 metres (16,001 ft) from its southern base in the plains near the municipality of Moshi to its summit height of 5,895 metres (19,341 ft).[2] Kilimanjaro is the highest volcano outside South America.[7] Kilimanjaro is a large stratovolcano and is composed of three distinct volcanic cones: Kibo, the highest; Mawenzi at 5,149 metres (16,893 ft);[8] and Shira, the shortest at 4,005 metres (13,140 ft).[9] Mawenzi and Shira are extinct, while Kibo is dormant and…

volcanic matter, away. By about 3 o’clock, the lapilli fell onto Pompeii. Each lapilli could not harm anyone, its weight as a whole collapsed buildings. Clouds of volcanic dust filled the air decreasing the visibility. At dawn the clouds departed, but lava flowed into the city. The first flow was slightly warm, slow, and an inch thick, but the flow following it was at boiling temperatures and moved at 50 miles per…
