Volcanology

Volcanoes can destroy the land all around them. There are volcanoes all around the world, some may be dormant then may become active. There are some volcanoes that destroyed all of the living things around them, such as, Vesuvius, and Mt. St Helens. Some volcanoes are very different from the others. There could be different ways a volcano could erupt. Vesuvius and Mt. St Helens both destroyed a great amount of land around them. Furthermore, the two volcanoes caused Earth quakes. In addition,…

This report is about Mount Etna. Mount Etna is a volcano found in Italy. “Mount Etna is the largest active volcano in Europe and one of the world's most frequently erupting volcanoes.” (Mount Etna: Facts) Mount Etna’s earliest known eruption was in 6190 BCE. The second known eruption was in 5150 BCE. These eruptions are known because of radiocarbon found in the area. The date of when this volcano was formed is not certain like most volcanos this one was formed on plate boundaries. Mount Etna is…

The map is almost uncannily similar to today's: a spray of black dots showing the recorded sightings of a foul grey haze spreading across Europe, from Helsinki to Naples, from Heligoland to Mallorca, and reaching eventually to Aleppo and Damascus – and all of it caused by clouds of ash from an immense volcano erupting far across the sea in Iceland. But this was a map made from data collected in 1783. The volcano was called Laki, it erupted for eight dismal months without cease, ruined crops,…

Petrography of host rocks The Venarch manganese deposit is accommodated by volcanic and plutonic rocks. The volcanic strata mainly consist of basalt, trachybasalt, andesite, and basaltic andesite which are intruded by monzonite, monzodiorite, granodiorite, and syenite. The plutonic rocks are mostly granular in texture; however other textures such as graphic and poikilitic textures are present. The dominant minerals are plagioclase phenocrysts, quartz, K-feldspar, and hornblende and accessory…

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…

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…

Volcanoes aren’t that bad, sure if you are near one and they happen to EXPLODE your dead, but for Mother Nature and our Earth volcanoes are extravagant creators of soil. Volcanoes are above ground and under water, both can drastically affect our Earth, living things, and soon to be living things. How do volcanoes affect people and environments? There are lots of volcanoes all over the earth some active, some not active, and some that will soon be active. We are not exactly sure how many active…

Volcanoes have a purpose to be on Earth. Volcanoes are on earth is because volcanoes are a natural way to cool off the earth. These volcanoes are releasing internal heat pressure. Volcanoes are erupting because this is how much pressure they have. “ Volcanoes can remove heat from the interior,” according to Oregonstate.edu. Volcanoes do wonderful things for Earth. There are many dangerous volcanoes. One of the most dangerous volcano is the Campi in Flegrei, Italy. Campi had more recent history…

Extraordinary Careers in Extraordinary Times-- The Volcanologist Volcanologists are scientists who partake in the study and analysis of volcanoes, in order to help us be more aware of their threat and to gain more information about them. They do this by collecting samples from volcanoes, using chemical dating technology, and observing data about the volcano. However, in a couple years, due to the rapid growth and development of artificial intelligence, this occupation may be changed in…
