The volcano is called the Mauna Loa, - Volcanoes can be really, really dangerous. It can animals, and plants. In a volcano eruption hot lava shoots out of a volcano. After a volcano eruption lava cools off. After the lava cools off it turns into solid rocks, which are called “Igneous Rock”. If the lava falls down to the water it cools off and makes landforms. For example: Hawaii would have not destroy people next to the volcano, been an island if the volcano that made it didn’t erupt. So Hawaii was made by a volcano’s lava also known as magma....   [tags: active volcanoes, eruption] 669 words

Forecasting Earthquakes and Volcano Eruptions - There are many pro’s for attempting to forecast an earthquake or volcano. Forecasting an earthquake or eruption saves lives and property, mainly by preparation, as there is no way to prevent these events with today technology. On February 4th 1975 in Haicheng China there was a magnitude 7.5 earthquake. Over a period of months there were changes in elevation in land, ground water and unusual animal behavior which are all precursors to an earthquake. Days before the 7.5 magnitude earthquake there were foreshocks that triggered an eviction warning that effectively saved over 150,000 lives or injuries....   [tags: preparation, prevent, technology, disaster]

The quake was large and rocked the nearby towns of Pompeii and Herculaneum, doing extensive damage that would take years to repair. Due to the limited knowledge of geology at this time, Roman scholars were unable to make the connection between the earthquakes and the possible peril of a Mount Vesuvius eruption.(BBC) Some even argue that the people didn’t even know Vesuvius was a volcano....   [tags: eruptions, pompeii, herculeam] 1691 words

Although, andesite magma dominate fragmental debris, some magma intrudes the cones such as sills or dikes. Due to this multiple intrusions, the strength of the structural framework is obtained and therefore composite volcanoes stand higher than those composed solely of the fragment materials....   [tags: vulcanology, earth sciences]

Since then the myths have all gone but the name Vulcano has remained as the symbol for all volcanoes. "A volcano is both the place and opening from which molten rock, solid rock or gas issues from a planetary interior" (Scarth 1994)....   [tags: Papers] 882 words

Why Causal Connections Do Not Solve the Gettier Problem - The purpose of this paper is to show that Goldman's causal theory of knowledge does not solve the Gettier problem. First, I will reiterate the Gettier problem. Second, I will show how Goldman's theory attempts to solve the Gettier problem. Next, I will show how over determination points out a major flaw for Goldman's theory. Finally, I will demonstrate that Goldman's theory does not work if the world we live in is not one of absolute truth and void of deception.

The Effects and Causes of Volcanic Activity - Volcanoes are formed when magma is expelled from the Earth’s surface, resulting in volcanic eruptions consisting of ash and lava. Over time, the lava cools and forms into rock on the Earth’s surface. Whenever an eruption occurs, the newly-formed rock from the lava layers continuously until the volcano takes its shape. Volcanic eruptions have taken place for thousands of years, and even today, according to the U.S Geological Survey (2010), there are approximately 1500 active volcanoes located throughout the world....   [tags: lava, magma, volcanic eruptions, climate change]

The 1815 Eruption of Mount Tambora - Mount Tambora, located on the Island of Sumbawa, Indonesia is classified as a Stratovolcano. Also known as a composite volcano, Tambora is a tall conical volcano (cone like structure) where layers of the walls are built by hardened lava and volcanic ash. The term composite is used to describe the volcano due to the composite layered structure built from sequential outpourings of eruptive materials1. Among the most common types of volcanoes, Tambora also shares its destructive prowess with best-known volcanoes such as Krakota (1883) and Vesuvius (79 A.D)....   [tags: Plate Tectonics ] 2292 words

Volcanoes in Australia and New Zealand - Why doesn’t Australia have volcanoes and New Zealand does.

No eruptions have been recorded in the past century. Volcanoes occur on the tectonic plate boundaries. Because Australia is in the middle of the Australian plate and it is impossible for any new volcanoes to form.

Mt.Vesuvius and its 79 AD Eruption - Volcano: A hill or mountain formed around and above a vent by accumulations of erupted materials, such as ash, pumice, cinders or lava-flow. The term refers both to the vent itself and to the often cone-shaped accumulation above it. (Scarth, 1994.) This definition can do Mt. Vesuvius no justice. Instead, I would describe it as one of the most hellish and population decimating volcanoes. Vesuvius lives…or lived.

However the Minoan population ended abruptly and seemingly simultaneously 430 years later, this left archaeologists and historians searching for the cause (Castleden 1990, 143). The main reason archaeologists are studying the reason for the downfall is because if a date was known, a more precise historical timescale could be produced that would give a more accurate chronology of ancient history during this time (Barber 1990, 221)....   [tags: Archeology Ancient History]
