Seismology Essays

earthquake made it possible for scientist to better understand what exactly causes an earthquake, along with understanding the immensity of the San Andreas Fault, all can be used to improve the safety of the city for its inhabitants. In fact the seismology, geology, and scientific world prospered after the earthquake as the earthquake provided plenty of data for the scientist to explore. From this data came theories like the elastic rebound theory that are still in use today. The magnitude of the

Undoubtedly one of the worst natural disasters in U.S. history, The San Francisco Earthquake of 1906, set the stage for understanding earths forces and how to handle them effectively. San Francisco's transformation into a destroyed city, effective response to wide-spread disaster, and expensive reconstruction were all hurtles for the city to climb back to its previous economic power. Despite these challenges, San Francisco was able to rebuild itself into an even greater and more advanced power.

Introduction: Living in Skopje, the capital city of a country that is subjected to many earthquakes, some stronger than others, made me interested in earthquakes and finding more about them. The strongest earthquake Skopje has experienced throughout history that caused a severe destruction was the earthquake in 1963 measured at 6.9 on the Richter scale and 6.1 on the Magnitude Moment Scale, which killed over 1,000 people and destroyed 80% of the city. This made me curious to look deeper into the

The Great Kanto Earthquake In September 1923, Tokyo became a hell on earth. In less than three days, an earthquake and subsequent conflagrations reduced nearly half of Japan’s capital to a blackened, rubble-filled, corpse-strewn wasteland of desolation. The areas affected were Tokyo, Kanto, The Kanto Plain, Yokohama, as well as the surrounding areas. The Great Kanto Earthquake is considered one of the most shocking natural disasters to occur during the 20th century. The unexpected disaster struck

1976 Tangshan Earthquake Introduction: At 03:42 AM on Wednesday July 28 1976, it was believed that the largest earthquake had occurred near the Tangshan (a large industrial prefecture-level city in northeastern China with approximately 1 million or more residents) in Hebei with a magnitude of 7.8. The earthquake struck at a very late mid-night (03:42 AM) where more than a million people laid sleeping and not evacuated. The entire earthquake was claimed to last for approximately 14 to 16 seconds

As being a child in the oilfield community for all of my life so far, the constant exposure has given unexplainable knowledge that I never actually strived for. I’ve known the process of practically it all, and I’m here to tell you, fracking and water disposal do not cause earthquakes in the extreme that is being spoken of all over the country. Fracking is the process of drilling into the earth with a high pressure water mixture of different chemicals and brine to be directed towards shale rock to

California is one of the most earthquake prone states in the U.S. Due to the state being on a fault line, it is constantly subjected to earthquakes whether they be mild or intense, which constantly puts the cities that lay on the fault line or are near it at risk. The earthquake described in Mark Twain's’ essay “The San Francisco Earthquake” is a rather “hysterical event” to Twain. He sees it as a miniscule or petite quake, where as others see it as a more drastic event. Twain's’ essay argues

My hypothesis, “If we experiment with a slinky to test the speed of S and P waves then the speed of the S and P waves will not be accurate to motion of S and P waves in the real world earthquakes because of the friction from the slinky”, was correct. In an earthquake P waves travel through the earth faster, as P waves can travel through solid rock as well as liquids such as liquid magma underneath the earth’s surface. S waves only move through solid rock, which means that the energy from the fault

THE PERUVIAN EARQUARE – PISCO - ICA 2007 On August 15, 2007, there was one of the worst earthquakes in the history of Peru and Latin America. It was measured 8.0 in the moment magnitude scale, lasted almost three minutes and affected all the Region of Ica. The Cathedral and three hospitals in Ica collapsed, killing more than 300 people. Figure 2. Map of the affected area. BBC (2007) According to the Earthquake Engineering Research Institute (2007), more than 519 people were killed, 1,090 people

Comparing 2 different Earthquake Cases Introduction: In this essay I will be comparing 2 different cases of Earthquakes, 1 in an MEDC (More Economically Developed Country) and the other in an LEDC (Less Economically Developed Country) both of a magnitude of 7.0. The two earthquakes that I will be comparing are the Kobe Earthquake in Japan in 1995 of a magnitude of 7 (for the MEDC) and the Haiti Earthquake in 2010 of a magnitude of 7.0 (for the LEDC).I will be comparing the impact after the Earthquake

Seismic facies analysis Seismic facies represent a group of seismic amplitude variations with characteristics that distinctly differ from those of other facies. A seismic facies is the manifestation of the underlying geologic facies or structural feature in the seismic amplitude data. These can be searched and identified from the seismic data by different approaches. These could be based on analysis of either the seismic waveforms or the seismic attributes

Haiti Earthquake 2010 Where I come from I have never seen or felt. Anything like the Haiti Earthquake. But I have heard a lot of the natural disasters stories like the Haiti Earthquake. Earthquakes has any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Seismic waves are made when some kind of energy stored in Earth’s crust. Natural events such as volcanic eruptions and meteor impacts can cause earthquakes, but most of the naturally-occurring

Imagine you are in bed when all of a sudden at at 5:12am, the earth begins to shake and the San Francisco 1906 Earthquake begins to rattle the city. The personal narrative “Comprehending the Calamity” by Emma Burke and the personal narrative “Horrific Wreck of the City” by Fred Hewitt both give you an idea of what the earthquake was like to wake up to. What do you think it was like? The personal narrative, “Comprehending the Calamity” tells the readers what the earthquake was like through the eyes

In 1906, an earthquake hit San Francisco, California. More than 3,000 people died. The earthquake that hit San Francisco was one of the largest earthquakes in northern California. It struck the coast of Northern California. "Horrific Wreck of the City" by Fred Hewitt and “Comprehending the Calamity:” by Emma Burke are both about the same thing but the two authors opinion on how this disaster affected people are completely different. “Comprehending the Calamity” by Emma Burke and “Horrific Wreck

The San Francisco Earthquake killed many - over 3000 to be exact. Not everything is known about the Earthquake but we do know a small bit, from Art. Paintings, Stories, Films, Photos and more. From these we know about what devastation was caused by the horrific events of the 1906 San Francisco Earthquake. Two of the many ways we know about the Earthquake is “Comprehending Calamity” a Personal Narrative by Emma Burke, and “The Horrific Wreck of The City” an Eyewitness Account by Fred Hewitt. After

A tail of one city, San Francisco, in two different periods of time. One in 1865 from Mark Twain, and the other in 1906 by Jack London. Clearly San Francisco as a city hadn 't changed that much in 41 years, but in reviewing the writings of Mark Twain and Jack London, one would think that they were a millennial apart. Twain took the light hearted approach to the catastrophe, while you could tell that the earthquake tore at the sole of London. In looking at the events as a whole, a much lighter

The Newcastle Earthquake occurred on 28 December 1989 with a magnitude of 5.6M. Although the earthquake did not measure very high on the Richter scale, it was shallow and that is why it shook Newcastle more than a deeper earthquake. The tremor left 13 people dead and hundreds of people injured and needing hospital treatments. The devastation to property was huge and caused damages to 3000 buildings, 35,000 homes and 147 schools. This earthquake quickly became one of Australia’s most serious natural

The 1906 Earthquake On Wednesday, April 18, 1906, at 5:12 a.m., a 7.8- magnitude earthquake awakened the city of San Francisco. The earthquake lasted for sixty-five terrifying seconds of violent shaking and ended with an unknown number of dead family members, neighbors, as well as hundreds of thousands of people trapped in a city surrounded by water. To make matters worse, a series of fires broke out throughout the city. For three days, persistent, raging fires challenged the possibility of a coherent

“I saw those policemen enveloped in a shower of falling stone. Their lives must have been blotted out in an instant.” this quote was from an article called “Horrific Wreck of the City” told by a man named Fred Hewitt. He was a eye witness in the 1906 earthquake, so was a woman named Emma Burke who was also in the disaster. The earthquake in 1906 is one of the most significant earthquakes of all time, says the USGS. Thousands of people died, the city was wrecked and fires were set aflame. The earthquake

4. The influence of Aswan Reservoir Loading on Earthquake Activity The change in level of any lake is controlled by the difference between the sources of inflow and outflow, compared to the total volume of the lake. One of the factors that have been observed to have a significant effect on the rate of seismicity at reservoirs is the way in which the water level changes in the reservoir [24] and [11]. Variations in filling rate are strongly influenced by the type of utilization of the reservoir,
