Imagine that you are sound asleep in the comfort of your own home when all of a sudden, you are awoken by a deep rumble as your house shakes to and fro. The rumbling stops, and you emerge from your house to inspect the damage. You see that your house was spared, but then notice that some of your neighbors were not as fortunate and had their houses destroyed. This is a scene that many people from the city of Prague, Oklahoma, experienced one memorable night in the fall of 2011 when a magnitude 4.8 earthquake rocked the little town of only twenty-five hundred (Galchen). The city of Prague, like most of Oklahoma, was woefully unprepared for that earthquake and the ones that occurred in the days following the initial earthquake.
Oklahoma is not alone, as states such as Kansas and Ohio have both seen drastic increases in their seismicity as well (Hall). The one thing all of these states have in common is that they all have oil and gas operations being conducted within them. Because of this, members of the media and environmentalists alike point the blame to a fairly old method of hydrocarbon extraction that picked up speed around the same time that these earthquakes began happening. This method, known as hydraulic fracturing (fracking), has been subject to immense scrutiny because of this correlation, and its future remains uncertain.
Due to its violent nature, it is easy to see how fracking can be blamed for induced earthquakes, but the data and science behind it suggest otherwise. Fracking was first used in the 1940s but gained popularity in 2003 when US oil and gas producers began focusing on undeveloped shale formations (MacRae). Since then, fracking has become an integral part of the petroleum industry. However, it is not the only newcomer to the areas where fracking is implemented. As mentioned earlier, states like Oklahoma and Ohio have seen drastic increases in seismic activity (Hall). People do not consider this increase to be natural and thus deem it to be man-made, which is induced seismicity by definition. Keith B.
Tectonic plate movement can occur as close as two and up to 450 miles below the Earth’s surface. According to the Indiana Geological Survey, Indiana’s fault lines are further underground than those in California and Alaska, causing more minor quakes in the Midwest. However, Hoosiers should heed the recent earthquake as a warning for future quakes. Earthquakes can and do happen in Indiana, and almost anywhere else in the world. This is the one natural disaster that people cannot avoid no matter their location on Earth. And, being unprepared can have devastating results.
Most of Arizona’s earthquakes are associated with the San Andreas fault as most of Arizona’s earthquakes are shocks from epicenters located in California. Arizona has had earthquakes with epicenters located in its borders and just like the ones located near the San Andreas fault, they are linked to a transform plate boundary and are dip-slip earthquakes. Much of the focus of these earthquakes can be centered around the Grand Canyon as much of the after-effects of these earthquakes caused phenomenons to occur in the Grand Canyon. Many rockslides took place in the Grand Canyon and plenty of the cracks found in the canyon’s rock layers are attributed to some of the earthquakes that took place in Arizona since the geologic landscape formed its current
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. This is a pro as this forecast saved thousands of lives and had the people of this area (knowing this was a place of seismic activity) took precautions, like that of earthquake resistant buildings, evacuation points, preparing disaster supplies among other preparations the following may not have happened or would have been less of a disaster.
Earthquakes in California are certainly not a surprise. What is a surprise is their unpredictability and randomness. Geologists say there is roughly a 50 percent chance that a magnitude 8 or more quake will hit the Los Angeles area sometime over the next 30 years. And, over the past twenty years, the Los Angeles area has witnessed several earthquakes, and in particular, two that were quite devastating; the 1971 San Fernando earthquake, and the January 17, 1994, Northridge Earthquake. Given the certainty that earthquakes will occur, they still seem to come as a surprise, and leave many communities unprepared to deal with their aftermath.
Hydraulic fracturing, also called fracking, is a technique designed to release the gas and oil from shale rock hidden underneath earth’s surface. The term fracking itself is referring to the point at which the shale rock is broken open by a high-pressure mixture of water, sand, and chemicals. Oil and gas fracking can be dangerous to the environment and also to humans. “In 2011, energy company Cuadrilla suspended test fracking operations near Blackpool, in Lancashire, after two earthquakes of 1.5 and 2.2 magnitudes hit the area. A subsequent study found it was highly probable that shale gas test drilling triggered the tremors” (BBC). Although these tremors were too small to do any damage above ground, this was still a test drill. If an oil rig were to become operational, the tremors could increase in magnitude, causing significant damage both above ground and underneath the earth’s
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans. The efficiently burning shale gas reduces carbon emission from electricity production plants, reducing carbon footprints on the environment. However, the process of hydraulic fracturing uses millions of gallons of pressurized liquid, which contains toxic chemicals, and some of this water is left over undealt with. The air near fracking sites is often also polluted and unsafe for nearby community residents. Injecting millions of gallons of water laced with toxic chemicals into the rock thousands of feet deep can cause earthquakes, causing a safety hazards for all nearby areas. Hydraulic Fracturing makes rare natural gases easily attainable, boosting the economy and reducing carbon emissions. However, the negative side effects such as contaminated water and air, make hydraulic fracturing a process that may not be worth the benefits.
At 5:12 a.m. on April 18th, 1906, the California city of San Francisco was awoken by a 7.8 magnitude earthquake. Chaos erupted with the earthquake leading to fire break outs throughout San Francisco (Cameron and Gordon. Pgs 69-73).The earthquake and the resulting fires caused destruction to majority of the city with buildings crumbling and igniting into flames. Many people died along with thousands and thousands of people being left homeless. This devastating earthquake left the city and United States in a financial crisis. Although the 1906 earthquake was one of the worst natural disasters in U.S. history, the city of San Francisco was able to overcome these substantial physical, social and economic impacts it had.
Ten million California residents who lived closely from the major fault lines could have been endangered in many extreme ways. (House, 56). A tragic thing was that after the earthquake a multitudes of fire followed right after. The situation led to the water mains being destroyed and the firefighter being left with no water to settle the growing fire which continued blazing. The bay water was planned on putting all of the dure out but it was to far in distance to be able to transport it (Earthquake of 1906, 2). The firefighters who were putting out the fire were either surrounded or being burned by the fire that was blazing in all directions (San Francisco Earthquake, 2). A resident who was present during the event mention that he/she saw men and women standing in a corner of a building praying, one person who became delirious by the horrific ways that were surrounding him while crying and screaming at the top of his lungs “the Lord sent it, the Lord”. Someone also mentioned that they experience themselves seeing Stones fall from the sky and crushing people to death. Reporters say there were 100 cannons going off (San Francisco Earthquake, 3). People who lived fifty miles away from the fire was able to “read the newspaper at
Hazards pose risk to everyone. Our acceptance of the risks associated with hazards dictates where and how we live. As humans, we accept a certain amount of risk when choosing to live our daily lives. From time to time, a hazard becomes an emergent situation. Tornadoes in the Midwest, hurricanes along the Gulf Coast or earthquakes in California are all hazards that residents in those regions accept and live with. This paper will examine one hazard that caused a disaster requiring a response from emergency management personnel. Specifically, the hazard more closely examined here is an earthquake. With the recent twenty year anniversary covered by many media outlets, the January 17, 1994, Northridge, California earthquake to date is the most expensive earthquake in American history.

Before one can see the devastating effects of fracking, one must first understand how fracking works. As previously stated, the main intent of hydro-fracking is to access and harvest natural gas that lies below the surface of the Earth. Having formed over 400 million years ago by the collision of tectonic plates (Marsa 3), the Marcellus Shale plays host to a gold mine of natural gas, which is currently at the center of the fracking debate in the Northeastern region of the United States. Unfortunately, access...
...king have been placed on shale fracking. This is where fuel is fracked from the harder surfaces, causing more affects to the earth. They do allow tight gas fracking, which is not a dangerous (Inside Climate News). Either form of fracking have many worried about what the future of the country will be.
Fracking has become a highly controversial and publicized topic due to rising concerns and growing analysis into the mutual benefits of hydraulic fracturing to retrieve natural gas and oil reserves. With concerns of water pollution, mismanagement of toxic waste and irreversible
Numerous reports have been given on the dangerous affects of hydraulic fracturing. One such affect that has been noticed is that drinking water wells near the fracturing sites have been contaminated. During the hydro-fracking process, injected fluids that help to break and keep open the rock bed where the natural gas is kept, have “been known to travel three thousand feet from the well (Goldman).” This fluid could have the potential to enter and contaminate any water well for homes around hydraulic fracturing sites. This incident is one of the major problems that people want to figure out and know about before they allow a fracturing site by them. It has been the most feared outcome of having a fracking site nearby, and it is highly appropriate. One site in Wyoming had this happen, “…in August, EPA reported that eleven of thirty-nine drinking-water wells near a Wyoming hydraulic fracturing operation were contaminated with chemicals used in the fracturing process (Hobson EPA).” In Pennsylvania, another such case occurred, “There have already been severe pollution cases in Pennsylvania, mo...
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
