Lava Records

Definition Lahars also called mudflows contain fusion of water and consolidated particles of gravel, ice, wood, and other fragments that flow from volcanoes are distinct, prompt, and gravity-induced outflows of drenched, high-consolidation mixtures.(Vallance, 2000) Types Primary lahars These are generated amidst outbursts by numerous eruption-related activities. Such lahars wiped out almost 37,451 people all over the world between AD 1600 and 2010. The Nevado del Ruiz disaster in 1985 caused…

The search for the legendary lost island known as Atlantis has been grabbing the attention of explorers, historians and philosophers for over 2,000 years. People to this day still argue about its location. Plato, the Greek philosopher, wrote about this ancient civilization in two of his dialogues. Although some argue that this place is fictional, there are scientific and geographical explanations as to why the city would have sunken. Also, there have been relics that were found that suggest they…

The Popocatepetl is a volcano that has captured attention since prehispanic times and until know for is activity, size and story. It is one of the highest volcanoes in Mexico as well as one of the most active. The fact that the is a large population living around this volcano makes it even more dangerous. The name “Popocatepetl” was given by the Aztecs, it means “smoking mountain”. They gave it this name because during their empire the Aztecs were able to witness options. The Popocatepetl has…

White hot lava bubbles as the beast shakes, it awakens. Ash falls from the sky as heat crawls down the mountain. The volcano erupts. Many people don’t know much about volcanoes, only that lava comes out. There are many different types of volcanoes, but all people think of or see when the word volcano comes up is death and destruction. However, volcanoes can help living things, and they can build as well. No matter where you live, volcanoes effect you. The question is, how? Volcanoes can…

The great Crater Lake in Oregon was once a stratovolcano named Mount Mazama. Mount Mazama had a very catastrophic pyroclastic eruption that produce about 12 cubic miles of magma. The Mount Mazama volcano has been recorded as one of the largest volcano eruption that has taken place in the last 10,000 years. The Mount Mazama volcano was one of the major volcanoes at the Cascade Range. The range of Mount Mazama’s summit was roughly between 11,000 and 12,000 prior to its climatic eruption. The…

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…

VMS deposits occur in a diversity of shapes ranging from flat lens shaped to large sheet-like sulphide mineral rich bodies (Allen, et al., 2002). The preferred environment for these deposits to form in is submarine near a seafloor opening i.e. black smokers, where hydrothermal fluids escape and precipitate on the ocean bottom (Evans & Moon, 2006). The mineralogy of Kidd Creek VMS deposits often consists out of more than 60 different ore minerals and ore-related gangue minerals, of which 90% or…

Mount Vesuvius is known as one of the most famous volcanos on the planet. It is in the Eastern Hemisphere, and does not lie on the ring of fire, which is somewhat rare. Mount Vesuvius in located on the continent of Europe and in the country of Italy. Its geographical coordinates are North 40 degrees and East 14 degrees. The tectonic plates below Mount Vesuvius are the Eurasian and African Plates. The plates that have interacted to form this volcano are convergent. It is still an active…

This happened in the famous lost city of Pompeii almost 2,000 years ago, after Mount Vesuvius erupted the whole city of Pompeii was covered with lava and ash causing everybody to die. Most of the people affected looked as if they were doing normal day things when their roof crashed in on them. More than 100 plaster casts of bodies have been made and put into museums. Therefore, heavy rains, weather…

Mount Vesuvius is located on Campania, Italy. It is one of several other volcanos that form the Campanian volcanic arc. Vesuvius consists of a big cone partly bordered by the rim of a summit caldera caused by the breakdown of a former and initially much higher arrangement. The height of the main cone has been continually changed by eruptions but was 4,203 feet in 2010. Vesuvius is a stratovolcano at the convergent boundary where the African Plate is being subducted below the Eurasian Plate.…
