A natural disaster occurs as the effect of natural hazard. The UN office for co-ordination of humanitarian affairs, defines natural disaster as the “consequences of events triggered by natural hazards that overwhelm local response capacity and seriously affect the social and economic development of a region.”. According to the UN office definition, not all natural phenomenons that occur on planet earth can be termed as natural disasters. A natural phenomenon becomes natural disaster when it proves uncontrollable during its occurrence. For instance, when hurricanes strike an uninhabited island, such a phenomenon cannot be termed as a natural disaster. In ...

In this paper we will discuss Etna volcano which is situated on 37° 45′ 18″ N, 14° 59′ 43″ E.
General Information
Etna is an active stratovolcano located on the east coast of Sicily, close to Messina and Catania. This is the highest active volcano in Europe. Now the height of Etna is 3329 m above sea level. It often varies from eruption to eruption. So, now the volcano is 21.6 m lower than it was in 1865. Etna is the highest mountain in Italy south of the Alps, it covers an area of 1250 square kilometers. Thus, Etna - the largest active volcano in Italy, surpassing its closest "opponent" Vesuvius more than 2.5 times. Throughout its existence Etna ...
The rock I will be examining in this report is granite. Granite – is the most commonly spread rock in the continental crust formed by the slow cooling and solidification of magmatic melting rocks in depth. Granite can also be formed during metamorphism – under the influence of high temperature and pressure, as well as under the influence of a variety of liquids and gases (fluids), rising from the depths. Granites play a huge role in the structure of the Earth`s crust and the whole continents, since this solid rock is one of the main materials forming the outer part ...
Tsunamis
Introduction
A tsunami (“a wave in port” in Japanese) are the marine gravity waves that are extremely large in length and height, and are the result of the up or down shift of ocean bottom areas with strong underwater and coastal earthquakes, occasionally, though, are the result of volcanic eruptions and other tectonic processes. Tsunamis are among those few natural disasters that are capable of causing huge numbers. First chapter of this research is dedicated to the causes of tsunami, wave formation mechanism, and waves’ various characteristics. The topic of the conducted research is highly relevant to our area ...

Introduction
On 11 April 2012 two huge earthquakes occurred beneath the floor of the Indian Ocean, off the coast of North Sumatra. Registering a magnitude of 8.6, the first was followed by another of 8.2 magnitude, which scientists subsequently identified as an aftershock. Neither triggered a large scale tsunami, which scientists attribute to the movement being of the “strike-slip” type, rather than the “thrust” type. However, strike-slip earthquakes are normally of a much lesser ...
Are you one of those adventurers who are planning to climb Mount Everest to reach the highest point on earth? You may have to change your plans already. Mount Chimborazo, located in the Cordillera Occidental, Andes Mountains, Ecuador has been found out to be the “Highest Mountain above the Earth’s Center”. Although, Mt. Everest has the highest altitude, Mount Chimborazo is said to be higher by at least two (2) kilometers than Mount Everest due to the “equatorial bulge” of the earth. (geology.com, 2014)
Mount Chimborazo is an Andean stratovolcano in Central Ecuador. It is also the tallest ...
1. How do continents grow and how are they modified
Continents arise due to movement of plates causing boundaries within the earth surface. Plates move through the oceanic crust along narrow zones between each other leading to the development of plate-tectonic forces. As a result, this forces leads to development of boundaries between the plates. This plates becomes the continents. Generally, continents arise because of continental drift that forces a single land mass on the earth surface to split and drift hence forming a continent. Their modification arises due to various plate boundaries that develop within the earth surface. ...
Abstract
The Altar basin found in the north western Sonora of Mexico, is a known subsidiary basin forming the present inactive part of the Colorado River delta. The sedimentary records of this basin show how the delta upgraded over a late Miocene. A structurally distinct aquatic basin at the northern end of the Gulf of California is found. Our interpretation of outcrop data, and information from exploratory wells, as well as analog seismic lines of Petróleos Mexicanos (PEMEX), and magnetic and gravity explorations from various sources pointed to the existence of three sedimentary sequences, which can be related at ...
My favorite food – Pizza
Who hasn’t enjoyed eating food? If you are dining at home or eating out at your favorite restaurant with family and friends it is always a treat. I love to eat pepperoni pizza, it is my favorite. Just thinking about a large pepperoni pizza gives me an irresistible hunger that becomes painful in the stomach if I do not get my favorite food. On entering the restaurant the delicious, warm smell of dough and a million spices tickles the nostrils and sends finger-like sensors to the brain. Sitting and waiting is torture and the anticipation of biting into ...
Background
More than six months ago, on June 27, a volcanic eruption occurred in Hawaii, its lava continuing to bubble till September. It crawled its way from the erupted volcano till the edges of the nearest village, causing people to evacuate from their homes. The leading edge of the lava flow was about 110 meters wide with an average speed of 5 meters per hour. The volcanic eruption occurred at the mountain Kilauea. Volcano experts quote Kilauea as “the most continuously active volcano on Earth; lava streaming into the ocean at a steady rate of around 5 [metres per second] ...

Vitrophyre Rhyolite in Valles Caldera
Vitrophyre Rhyolite is a type of igneous rock found in the Sante Fe and Valles Caldera areas of New Mexico (see map). Rhyolites are the extrusive equivalents of the plutonic rocks and hence the Rhyolite outcrops closely resemble granite formations. They are composed of high content of Silica and low in iron and magnesium. The Rhyolite melts are intensely polymerized and their lavas are very viscous. The Rhyolites are also known to occur in volcanic plugs and dykes.
Figure 1. The cross sections and the geological maps of the Vitrophyre ...
Volcanoes - geological formations on the surface of the earth's crust or another planet's crust where magma reaches the surface, forming lava, volcanic gases, rocks, volcanic bombs and pyroclastic flows.
Volcanoes are divided according to the degree of volcanic activity on the active, dormant and extinct. An active volcano is considered to be a volcano erupted in historical time period or during the holocene. The concept of "active" is quite inaccurate, since the volcano, which has active fumaroles, some scientists refer to the active, and some refer this volcanoes to be extinct. Sleepers are considered to be inactive volcanoes, ...
A Review
- Introduction
In summary, the article by James Wood and Alex Guth entitled “East Africa's Great Rift Valley: A Complex Rift System” provides information about the East Africa Rift Systems. The geology of the rift system was described. Also, the formation of the said rift system was discussed by providing a model supporting the geology of the rift system. Overall, the article strikes as a journal with a theme that concerns the geology of the East Africa Rift System. However, it must be important to emphasize the strong and weak points of the article. Needless to say, this paper ...
1. Meteors’ Hunting in the Antarctic Glaciers
The Antarctica is a popular and unique area for finding meteors because of the extremely cold weather conditions in this area (Gonzalez). Scientists find meteorites easily in the Antarctica since the meteorites are frozen in glaciers. Moreover, these meteorites are well-preserved unlike those that fall on earth or the sea, where they are hidden among other objects.
Identifying meteorites in glaciers is relatively easy. Since meteorites are dark, they are easily visible against an ice background. Moreover, many of them are preserved for years owing to the freezing temperatures of the glaciers. ...

Earthquakes are vibrations of the Earth that are caused by the rupture and sudden movement of rocks along faults or breaks within the earth's crust. The elastic-rebound theory is a model used to explain the origin of earthquakes. It illustrates the buildup of elastic strain from stresses within the earth's crust and the abrupt release of energy along faults as the rocks return or rebound to their initial state (Ristau 249; Hamblin and Christiansen 510). The point within the Earth where the earthquake's energy is generated by the initial slippage or movement is called the focus. The epicenter is ...
Geography is one of the ancient earth science. The word ‘Geo’ meaning ‘Earth’ and ‘graphy’ meaning ‘to describe’ was first used by Eratosthenes, a Greek scholar in third century B.C. Geography is basically the study of the earth’s surface and associated changes and impacts associated with it. It is the study of the interactions of all physical and human phenomena and also the landforms created during these interactions. Physical geography is one of the main discipline of geographical science. It is mainly concerned with the study of the spatial patterns of weather and climate, soils and vegetation, water ...
The Sequoia and Kings Canyon in the United States is famous for having the highest and the jagged relief in the entire Sierra region. The rugged topographical nature of these parks is attributed to the formation of the Sierra Nevada mountain range in eastern California. According to Liu and Shen, the formation of this mountain range has been the subject of profound controversy (299). Huber suggested that the uplifting of the range, now approximated at slightly over 2800m above the adjacent lowlands, occurred in the past 20 million years (Liu & Shen 299). A number of subsequent seismic studies conducted ...
Introduction
Plate tectonics is important because it explains the reasons for the deformation of Earth’s surface. Plate Tectonics theory assumes that the Earth’s surface was broken into several small plates and the plates have collided with each other to form the continents. The theory explains that the oceans and continents also move in addition to the tectonic plates. It also explains the global distribution of earthquakes and volcanoes. The plate tectonics explains the major features of the earth, such as the continents and oceans, the earthquakes and volcanoes and the mountains and valleys. The theory explained that the ...
How inequality and inequity impacted death rate and government response with the eruption of Nevado del ruiz volcano?
This paper analyzes how inequality and inequity in the developing countries like Columbia contributes to vulnerability during the natural disasters. In relation to Armero, the government failed to provide the necessary information before the eruption of the Volcano. The government failed to provide the necessary facilities and resources to rescue the victims of the volcanic eruption. The unequal distribution of resources in Columbia led to poor action and response to disasters like the volcanic eruption. Poor or little investment in disaster management made Columbia fail to predict the dangerous volcanic eruption in Armero. Columbia failed to allocate adequate resources ...

Volcanism refers to the eruption of magma or molten rock, or hot water and steam, including volcanoes, pyroclastic fragments, geysers, as well as fumaroles on top of the surface of a planet (Encyclopedia Britannica 1). A volcano refers to the vent through which gases and magma are discharged. When a planet loses its internal heat it results to volcanism. When a rock that is close to the surface becomes hot sufficiently enough to melt, it results to a volcano being formed.
On the Earth, volcanism often occurs in association with plate boundaries. Where two plates move apart, for instance ...
Understanding of Pompeii about Mount Vesuvius eruption in AD 79
When the Vesuvius erupted in AD 79, it caught the population of Pompeii by surprise and utterly unprepared. Though we know now that all the signs of possible volcano were there in AD 79 but the residents of those times had no idea of the warning signs. We only get to know about the tyranny through the preserved letters from Younger Pliny who was an eye-witness to the disaster. Through him and his account we have gained insight of the reactions and effect on the people caught in the natural disaster.
Younger Pliny’s letters leave no shadow of ...
Introduction
The name diamond owes its origin to Greece. The term is a corruption of the Greek term Adamas, which means the invincible or the unbreakable. In mineralogy, diamond refers to an allotrope of carbons, which is capable of transiting from one state to another. The carbon atoms within the mineral are arranged in a cubic-centered crystal known as the diamond lattice. The diamond mineral has the formula C and exists in Isometric-Hexoctahedral (cubic) crystal system. It is also essential to note that diamond exists in the space group C63/mmc.
Diamond exists in different varieties, as distinguished by their colors. ...
In general, global warming happens when the earth’s surface temperature rises. Scientists have emphasized that the warming of the earth is a natural process. Greenhouse gases are vital in maintaining an optimal temperature for the survival of all living organisms (Spencer, 2007). While it is true that such warming is important, excessive greenhouse gases may result to substantial increase in temperature (Spencer, 2007). Such increase in temperature may have dire consequences to the planet.

Introduction
This research paper discusses the phenomenon of earthquakes – the geography and distribution of where they occur, and the explanations of the forces and processes involved. The theory explains why they occur more in some places than others and describes related phenomena including volcanic activity.
The Research
The accepted theory of the cause of most earthquakes cites the continuous movements of huge sections of the earth’s crust (known as the lithosphere), which comprises tectonic plates (Earthquakes and Plate Tectonics” 1977), which are further classified as either oceanic or continental plates, dependent on their location on the Earth’s surface: beneath the ...
Mauna Loa Volcano within Hawaii largely erupt a rock type referred as basalt (HCV, 2008). When in molten state, basalt generates liquids of high fluidity. The fluidity of the molten basalt supports the flow of lava that is why the Mauna Loa Volcano generally has gentle sloping sides (HCV, 2008). The high eruption rate occurring at Mauna Loa Volcano, together with steep slopes, favors far and fast flows of lava or magma.
In contrary, Mayon is categorized as a composite cone or stratovolcano. It is made of deposits formed primarily by four main forms of volcanic activity: pryoclastic flows, ...
Introduction
For more than 150 million years, dinosaurs roamed across the earth. However, most dinosaurs became extinct suddenly within a short time. The last of the dinosaurs are estimated to have died about 65 million years ago. The cause of their extinction continues to be a mystery, with a number of factors such as diseases, climate change, geologic events and changing plant communities being thought to have played a part in the demise of dinosaurs. Of late, theories of dinosaur extinction have been the subject of much controversy and debate. The explanation that seems to have the support of many ...

Igneous, what are they? Igneous is a type of rock which is formed when magma or lava is cooled and solidified. Basically melting is caused by an increase in temperature, pressure decrease, or changes in composition.
Extrusive vs. Intrusive: Intrusive is the type of rock which is cooled slowly, in such rocks we can see a better crystal growth, though extrusive is the type which cooled quickly, in result these rocks have less crystal growth and are fine grained.
Texture (classifications) : Shape, orientation, size and distribution are of the mineral grains and the intergrain relations determine the texture. ...
- What is a Volcano?
A volcano can be described as a mountain that leads to a pool of molten rock present below the surface of the earth. Upon building up of enough pressure, an eruption of the molten lava occurs. Eruptions can cause lava flows, hot ash flows, lateral blasts, avalanches, mudslides, falling ash, and floods. Tsunamis and earthquakes are also possible consequences of such volcanoes (Wicker).

When the magma from the Earth’s interiors erupts to form lava deposits and ash flows on the surface due to pressure, a volcano is said to ...
The theory of plate tectonics describes the widescale movements of the lithosphere of
the earth. The model is based on the ideas of continental drift, which first gained acceptance in
the early 1900s. The geoscientific community granted the theory even more validity after the
notion of seafloor spreading appeared in the late 1950s. Basically, the lithosphere is not whole
but instead is separated into either seven or eight major plates, depending on the definition that
you use. Every meeting point between plates has its own relative movement, either transform,
convergent or divergent. Volcanic activity, mountain creation and earthquakes all occur along
these edges, and the plates move laterally relative to one another ...
Depth of the Earth is mysterious and far less accessible world than the space surrounding our planet. There is no device yet that could penetrate the depths of the planet. The deepest mine in the world has a depth of 4 km whilst the deepest borehole in the Kola Peninsula - 12 km. It's only 1/500 part of the radius of the Earth! However, people have learned to "drop in" to the depths of the Earth. The main method of studying them is seismic (from the Greek. "Seysmos" - an earthquake). From earthquakes or artificial explosions in the bowels ...
Earthquakes
Earthquakes produce vibrations that are recorded, detected and measured with the use of the seismographs. Seismographs amplify the ground motions by a million times more than the motions beneath making a zigzag transcribes that are known as the seismograms. This data is relevant for the determination of the focal depth of an earthquake the time and the epicenter of the phenomena. In addition, approximations can be complete with relative sizes and amounts of force it produced. The focus hypocenter of the earthquake is the origin of the fault where rapture initiates. The depth in kilometers and map locations in ...

The contribution of Alfred Wegener
William C. McCullough
LAIS 370 History of Science
Colorado School of Mines
Abstract
This paper discusses the role of Alfred Wegener in the discovery of the Plates tectonics theory. It is believed that the modern day plate tectonics theory is an advancement of continental drift theory which was discovered by Wegener. The study will seek to explore his efforts and contribution to modern science and how he has helped to shape the world.
Overview
Plate tectonics also known as continental drift theory describes that the earth was at one time many years back a super continent whereby all continents were ...
Continental drift is an idea developed by Alfred Wegner which states that the continents are drifting away across the ocean. He also suggested the plate tectonic theory in the year 1915. The theory states that, all continents were brought together into a mass land million of years ago. The key evidence presented in this case is that, African and South American continents fit each other perfectly if they can be enjoined. In addition, it has been evidenced that similar fossils are found in different continents which implies that, at one point in time they used to be together. The ...

On May 18, 1980, after two months of grumbling, Mount St. Helens erupted and this blast profoundly changed the looks of the vast area around the volcano. This cataclysm, though being tremendously devastating: killing 57 people, flattering 230 square miles of forests and blowing 1,300 feet off the peak, provided the perfect background for studying the early stages of forest’s development as well as the process of eco system regeneration after such a vital act of devastation. Right after the eruption occurred, some areas got absolutely avoid of life; on the other parts some species survived, but ...

Global warming is a climate phenomenon, which is responsible for the increase in temperature of earth over the years. It is one of the issues that has kept environmentalists at toes because of the draconian effects it could have with respect to planet earth and human existence and survival. There are several reasons, which facilitate the increase in Global warming, both Natural and Man Made. Natural reasons for global warming, though, are hugely miniscule and insignificant when compared to the human causes of global warming.
Natural causes of Global warming include Solar Output, Milankovitch Cycles, Water Vapor, Volcanic Eruptions ...
An aquifer is an aggregation of saturated rock that water passes through quite easily. They are both porous and permeable to water. They include rocks such as conglomerate, sandstone, fractured limestone and unconsolidated sand and gravel. Also, volcanic rocks that are fractured such as columnar basalts are good aquifers. In essence, some rocks with low porosity are poor aquifers. Examples of such rocks with low porosity include schist and granite. However, when schist and granite become fractured they become excellent aquifers. The boundaries of aquifers are usually graded into other aquifers, in essence, an aquifer could be a part ...
Earthquakes are destructive natural phenomenon caused by tectonic activity occurring along plate edges and faults. They generally have a trail of destruction owning to the large areas affected, as well as the suddenness and unpredictability. The higher the magnitude of the earthquake on the Richter Scale, the greater the destruction it is likely to cause. Damages include the destruction of property, loss of life, disruptions in vital infrastructural services such as power and water supply, transportation and communications. Earthquakes can also have a major economic impact.

The Igneous rocks, also referred as Plutonic rocks are one of the main rock types apart from metamorphic and sedimentary. These rocks can be formed either by intrusive or extrusive process depending on the location on the earth’s surface. The cooling and crystallization of magma (melted rock) inside the ground or above the ground creates the igneous rocks. Eruption of volcanoes also causes the formation of Igneous Rocks when the magma intensifies above the surface of the earth. The magma that rises above the surface is referred as Lava and the igneous rocks form when ...
Unrestrained Forces of Nature
Throughout human history, natural disasters are one of the unhindered events in everybody’s life. These natural disasters go in variety: earthquake, tsunami, hurricane, flood, avalanche, heavy typhoon, and so on. No matter how great the development of technology and knowledge of men is these events simply come natural. However, being natural doesn’t mean that they come into effect without any cause from natural and/or unnatural things. This is the reason why for years, men became able to predict the occurrence of such disasters. A prediction is not the information on where exactly a disaster will occur or ...

Long time ago like around four thousand years ago, the Greek civilization called Minoans made abode on the island of Crete south of Greece. The Minoan civilization took place between 2000-1500 BC. These Minoan people were farmers, artists as well as fishermen who sailed the rivers surrounding them. They were seafaring people who depended on their power, the navy and prosperity. Nature inspired the Minoans who loved it very much. At around 2000 BCE, the Mycenaean conquered the Minoans after the volcanic eruption that sank the islands of Thera hit it. The two civilizations had much in common, though they still were quite different. ...

Geometric and Arithmetic progression
A series is defined as a set of number whose sum equals to a constant A. for example, 4 + 10 + 46 = 60. Sometimes, a series is also known as progression. There are two types of series: Arithmetic and geometric series. In arithmetic series, successive terms differ by the same constant, d. For example, b + (b +3d) + (b +6b) + (b+9b) + . . . + (b + (n-1)d. The sum of terms in an arithmetic series Sn =, where a = first term of the series. In geometric series, successive terms have a common ratio. In this case, the sum of first n terms Sn = b + br + + + . . . + + . The last term of the expression is (Bluman, 2005). ...
