This is just for a little fun on how my blogging has been for me over the past few months that I have been blogging. I hope you can relate to me in some way like this. If you do, then let me know in the comments. Thank you, and enjoy!
Power plants and earthquakes do not mix very well when one happens. Earthquakes are one of the greatest natural disasters to occur any where in the world, especially if it is on the U.S. west coast. Power plants are especially at risk from earthquakes as one would cause large amounts of damage to it. Some power plants, such as solar and wind, would not cause much trouble, but fossil fuel and nuclear would be a major concern as both would cause great harm to the environment around them. We shale explore the risks that these earthquakes have on these power plants and which ones should be paid close attention to.
The United States is overwhelmingly dependent of fossil fuels and nuclear power for almost all of its commercial energy. American power generating plants are at some risk to earthquakes. Some power plants are located perilously close to or along earthquake fault zones. The vulnerability of energy production facilities to an earthquake depends on two factors: the proximity to known fault lines, and the ability of the power plant and its supporting infrastructure to withstand an earthquake, which depends on its design, construction, upkeep and age. Damage to nuclear reactors is of utmost concern to the public. However, damage to large fossil-fuel based plants is also an issue, as their supporting industrial and transportation infrastructure is vulnerable to ground liquefaction.
Most people are familiar with the major earthquake zones associated with Earth’s tectonic plate boundaries from Geology 101, but the real world is much more complicated, and very often, we can underestimate it. This has already happened with the Fukushima nuclear power plant disaster in Japan in 2011. When a 9.0 earthquake struck the island nation, quickly followed by a tsunami, it cause the plant to lose power and unable to control their nuclear reactors.
By the time they did, the damage was already done. Three reactors over heated, explode and released radiation across the island nation for three days. If such an event could happen there in the island nation from across the pacific ocean, then it could potentially happen here in the U.S. as well with a similar and disastrous result.
The U.S. Geological Survey has mapped many other potentially hazardous seismic areas across the country in the past few decades. Many of these zones happen to be in densely populated areas, where the seismic danger was not known when the power plants were built. Human-induced earthquakes are also an issue. The possibility of earthquakes strong enough to damage U.S. power production infrastructure is very real.
In the map provided above, there are a large amount of power plants across the US. Some of them, which are in big groups like in North Carolina and California, are solar and wind, but most of them, which are mostly scattered, are fossil fuels and nuclear. Many of these power plants lie dangerously close to where earthquake faults lie and are thus in earthquake risk zones. Hawaii, being an active volcanic island, does possess some earthquake risk and there are at least four power plants that lie there. In Alaska, many power plants lie across the state, given that Alaska is mostly a power production state, and the plants south of the state are at the greatest risk of earthquakes from the Denali Fault that lie’s there.
In the mainland of the US, there are a series of earthquake faults along the west coast of the country, which gives out a great risk zone for earthquakes. Many power plants lie in many of those risk zones and which some of them are fossil fuels and nuclear. There is also a risk in the central area where many power plants lie. That area is actually where the New Madrid fault lies and it provides great risk for the power plants in that area as well. There is also a small risk area in South Carolina as well. This area actually had an earthquake occur in 1886 that had a magnitude of 6.9-7.3 and caused great damage in the area. If that were to happen again, then there would be some risk there for the power plants in the area.
Earthquakes are a great danger that no one is to underestimate when one does happen. Power plants in the US have to make sure that they are safe from earthquakes, such as being in areas where there is the least amount of risk and making sure they are stable enough to resist an earthquake, especially the fossil fuel and nuclear power plants. If one or the other are to be damaged in any way from an earthquake, it would affect the environment around the area for generations to come. This is why we must ensure the safety of the power plants that are closest to earthquake risk zones, so that they would stay safe and keep the power flowing, as well as keeping the environment protected. The risk of earthquakes to power plants is real, and we must take the careful steps needed to keep them safe and stable enough to ensure that we can live our lives as safely as we can be.

The word ‘CAJUN’ is derived from the French word ‘ACADIAN.’ The word ‘Acadian’ describes the 17th and 18th Century people from an area of Canada called Arcadia or Arcadie. The popular meaning for the word ‘Acadie’ is ‘earthly paradise,’ from the language of the Micmac Indians, who inhabited the area at the time. Usually, the word Cajun is used to describe those French people from south Louisiana. But the term Acadian is sometimes used; and when one looks into it, they find that their ancestors in fact were Acadians from Canada. Acadians and Cajuns are the same, yet they are different. We will explore the history behind the two words and how they compare to each other.
The word “Cajun” did not come into being until sometime in the late 18th Century and is strictly a South Louisiana word. Up to World War II the word “Cajun” was somewhat of a source of embarrassment and ridicule. This came about because it suggested “a poor and uneducated person who spoke mostly French and some, if any, broken English.” It was not until the late 1940’s and early 1950’s that the Cajun population realized that this negative attitude was causing the eradication of their culture and the lost (sic) of their identity as an ethnic group. Through the efforts of many concerned people and organizations, a movement was designed to turn the negativism (sic) around into positive thinking and encourage proud feelings about the history and culture of their ancestors and the preservation of their French language. The heart of the Cajun culture is its language. This is on-going.
The 22 parishes designated by the Louisiana congress as “Cajun Country” is also known as Acadiana. There’s a great story behind how the term Acadiana was coined. The Acadians were French settlers who settled the area (now known as Nova Scotia) in the 1600’s. In the mid 18th century, they were exiled by the British. Over the following 30 years, several thousand of the exiled Acadians made their way to south Louisiana. Over the next 100+ years, the Acadians became the dominant culture in certain areas of south Louisiana. They retained much of their culture, and absorbed some of the other cultural influences. The German, Spanish, French, English, Indian and other cultures added to the Acadian culture to produce the Cajun culture. The word “Cajun” comes from the word “Acadian”, just as “Injun” is a variant of the word “Indian.” So, the Acadians were French settlers in 17th-18th century Canada. When they were exiled, they were no longer a single group. But the Acadian people survived in other cultures, sometimes merging into those cultures, and sometimes (as in south Louisiana) being a dominant culture. Today’s Cajuns may have roots that go back to the Acadians. But along the way, you will probably find German, French, Spanish, etc. ancestors that merged with the Acadians.
Cajun and Acadain means a lot when together and define a people for who they are. These people have a culture and a way of life as well that we have not explored into very much, but these people are very unique in their own way. They have a special french like language, spicy foods, an arrange of festivals, special arts, fun music and humorous content as well. They are an interesting people that should be worth a look into further. Cajun and Acadain are terms that tell us of a group of people that have their own way of life, and they should be recognized for what they are and how they are defined by it.
The Four Corners refers to a location where four states of the United States meet. These corners include the states of Colorado, New Mexico, Utah, and Arizona. The Four Corners is the only unique landmark in the United States where four states actually intersect at one geographic point. A tourism destination by itself or a perfect addition to Arches and Canyon-lands itineraries, Four Corners is a spiritual journal into sweeping landscapes with profound human and geologic history. We will explore what the history of these four corners and why they are so symbolic in the region.
The Four Corner region was part of Mexico until 1848 when the Mexican-American war came to an end and the region ceded by Mexico. In 1861 the Congress established the territory of Colorado, and in 1863 it created the territory of Arizona from the western part of New Mexico Territory. The boundary between the two territories was defined as a line south of the southwest corner of Colorado Territory. Congress had earlier demarcated territorial boundaries using longitude and latitude lines or physical features such as a river, but in this instance, it sought to establish a point at which four territories would converge regardless of survey errors that were likely to occur during the demarcation process. In 1868, the government began surveying the territories with the aim of establishing Colorado as a state. Colorado became the first of the four territories to be declared a state. On January 4, 1896, Utah became the second territory to be declared a state. On January 06, 1912, New Mexico became a state, and on February 14, 1912, Arizona became the last of the four states to be admitted.
Following government surveys that revealed a terminus of the Four Corners states’ boundaries joining in one place, surveyors erected the original Four Corners Monument in 1912 as a simple cement pad. In 1992, the monument evolved to a copper disc within a granite surface and 2010 brought new improvements. Two intersecting lines through the center of this disc mark the boundaries, accompanied by the seal of each of the Four Corners states. The Navajo Nation Parks and Recreation Department administers the Four Corners. Around the monument, Native American artisans and craftsman sell their handmade jewelry, crafts and traditional foods from numerous booths and shops. The monument’s visitor venter features information about the native cultures of the region.
The convergence of the four states led to the rise of the region, but the accuracy of the monument has always been doubtful. Initially, the surveyors were required to follow the latitudes and longitudes, but they instead placed markers that that did not tally with the points. In 1919 and 1925, border claims led to a court case between New Mexico and Colorado but the Supreme court ruled that the boundaries would remain as placed by the markers. In 2009 the boundary issue found its way to the Congress after the media stated that it had been placed 2.5 miles from the correct location. The matter as used to rest when US National Geodetic Survey state that the surveyors had used the Washington meridian and not the Prime Meridian as the reference point. After modern survey equipment was used to locate the exact boundary, it was determined that the monument lies 1,807 feet from where present day surveyors would place it. However, the US National Geodetic Survey, the Supreme Court, and the Navajo governments agree that the surveyors did exemplary work given the survey technology at their disposal. The boundary was thus upheld.
The Four Corners of the United States marks the only place in the United States where the corners of four states actually meet in one place. This is very significant as no where else in the United States is where this particular geographical feature happens. It is also significant as this defines the states that formed the country as we see it today. It also tells the tale of the Native Americans in that region and the history that went in behind the formation of these states that we know them as now. These four corners of the four western states are more significant than what people take credit for, which is why people must recognize just how important this region of land is and the history that went into it as it defines the western part of the United States that we know of it to this day.
We end this series with this last image here which shows a great sunset in the Smoky Mountains, which is a very grand scene to end this series. Science Daily details science behind these striking sunsets and the phenomenon of scattering. Tiny molecules change the direction of light rays in the atmosphere, causing them to scatter. When the sun is low on the horizon at sunset, sunlight passes through more air. Blue and violet are short-wavelengths and are scattered much more than other colors on the spectrum. That is why we see a blue sky during the day when the sun is high. When there is more atmosphere, that means there are more molecules to scatter the violet and blue light away from your eyes. Because red has the longest wavelength of any visible light, the sun is red when it’s on the horizon. This also explains why sunsets tend to exhibit colors of yellow, red, and orange. The details of the sunset are determined by the wavelength of the light and the size of the particle.
According to National Geographic, you may see more vibrant sunsets based on the seasons. In the east, the fall and winter create marvelous sunsets because the air tends to be dryer and cleaner for the path of sunlight. Pollution also tends to mute and muddy the colors of sunsets because large particles in the lower atmosphere tend to have that effect. In places where there is a lot of haze, it is less common to observe dramatic colors.
In this final image, the sun is setting beautifully upon the mountain hill-tops of the Smoky Mountains in North Carolina. This image was taken by Christopher Mobley who uploaded it on the 31st of July, 2012, and it show the stunning scene of the sun falling into the distance to beyond the horizon of the Smoky Mountains. A truly perfect end of the Power of Nature series with this scene of the adventure coming to an end here as the day there draws itself to a close.
For this next image, we move back down to Earth and head to downtown Raleigh, where a winter storm is happening. Winter storms derive their energy from the clash of two air masses of different temperatures and moisture levels. Winter storms usually form when an air mass of cold, dry, Canadian air moves south and interacts with a warm, moist air mass moving north from the Gulf of Mexico. The point where these two air masses meet is called a front. If cold air advances and pushes away the warm air, it forms a cold front. When warm air advances, it rides up over the denser, cold air mass to form a warm front. If neither air mass advances, it forms a stationary front.
The snow itself is commonly formed when water vapor undergoes deposition, which is when water vapor changes directly to ice without first becoming a liquid, high in the atmosphere at a temperature of less than 32°F and then falls to the ground. The winter storm itself is identified as an ice storm, which is a type of winter storm caused by freezing rain. The U.S. National Weather Service defines an ice storm as a storm which results in the accumulation of at least 0.25-inch of ice on exposed surfaces. It forms when a layer of warm air is between two layers of cold air. Frozen precipitation melts while falling into the warm air layer, and then proceeds to refreeze in the cold layer above the ground. This creates freezing rain or a glaze of ice.
The picture that is taken here shows an ice storm happening in the city of Raleigh, North Carolina on the 23rd of January, 2016. We see ice and snow on the roads, trees and on the ground near where the city skylines are located. There are very few cars on the road as the ice makes them slippery and not everyone would be driving on such roads with this much ice on them. Ice storms can be very hazardous when people are driving on the roads.
The next satellite image that will be looked into in this series will be that of a hurricane. Just like how mid-latitude cyclones are not hurricanes, hurricanes are not mid-latitude cyclones like the one in the previous image. Hurricanes are the most violent storms on Earth. People call these storms by other names, such as typhoons or cyclones, depending on where they occur. The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called “hurricanes.” Whatever they are called, tropical cyclones all form the same way.
Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is an area of lower air pressure below. Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that “new” air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the surface. Storms that form north of the equator spin counterclockwise. Storms south of the equator spin clockwise. This difference is because of Earth’s rotation on its axis. As the storm system rotates faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flows down into the eye.
When the winds in the rotating storm reach 39 mph, the storm is called a “tropical storm.” And when the wind speeds reach 74 mph, the storm is officially a “tropical cyclone,” or hurricane. Tropical cyclones usually weaken when they hit land, because they are no longer being “fed” by the energy from the warm ocean waters. However, they often move far inland, dumping many inches of rain and causing lots of wind damage before they die out completely.
The image above is a satellite image of Hurricane Florence from 2018 that was taken by NASA’s astronaut Ricky Arnold from the International Space Station on Sept. 10, as it heads toward the U.S. East Coast. Classified as a category 4 storm, with wind speeds up to 130-156 mph, it is one of the most powerful storms to strike the U.S. east coast, causing large amounts of damage to the region and much property loss. Some people are still struggling after the hurricane has long since passed.
