The late 1800s and early 1900s also saw scientific inquiry into earthquakes begun by Japanese researchers. Seikei Sekiya became the first person to be named a professor in seismometry ; he was also one of the first people to quantitatively analyse seismic recordings from earthquakes. Secondly, Would you believe that giant snakes, turtles, catfish, or spiders live underneath the ground, and it is their movements that create earthquakes? Maybe you wouldn't, but your ancestors did. Ancient peoples had many fanciful explanations for earthquakes, usually involving something large and restless living beneath the earth's surface.
Aristotle was one of the first to attempt an explanation of earthquakes based on natural phenomena. He postulated that winds within the earth whipped up the

These earthquakes were followed on Sunday, November 1, 1755, by a cataclysmic shock and tsunami that killed an estimated 70,000 people, leveling the city of Lisbon, Portugal, while many of its residents were in church. This event marks the beginning of the modern era of seismology, prompting numerous studies into the effects, locations, and timing of earthquakes.
Prior to the Lisbon earthquake, scholars had looked almost exclusively to Aristotle, Pliny, and other ancient classical sources for explanations of earthquakes. Following the Lisbon earthquake, this attitude was jettisoned for one that stressed ideas based on modern observations. Cataloging of the times and locations of earthquakes and studying the physical effects of earthquakes began in earnest, led by such people as John Michell in England and Elie Bertrand in Switzerland. confirmed following the 1835 Chilean earthquake by Robert FitzRoy, captain of the H.M.S.Beagle, while Charles Darwin was onshore examining the geology of the
• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.
The first major earthquake in this series was in December 1811 where the center of the earthquake was said to be started in northeast Arkansas; the people of Arkansas were the first to be shake. How did all this start? Earthquakes start when rock beneath the earth’s surface shifts in a swift and sudden way. I believe we see the earth changing overtime, but its overtime where as an earthquake is not. An earthquake is under the surface and we only see the effects of one. How do we know the New Madrid Earthquake occurred? It’s a tough question, but there’s enough documentation at our fingertips to answer the question. Many of the people that lived during the earthquake shared their experience, Crist wasn’t the only one. And that’s how we can say it’s
Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.
On April 18, 1906, in San Francisco, California there was an earthquake that was a major geological disaster that affected people in many ways. According to www.History.com, San Francisco had a population of around 400,000, and 3,000 people. The earthquake destroyed over 28,000 buildings and around 250,000 people became homeless. The damage costs were $500 in 1906. The magnitude of the earthquake was estimated to be a 7.8, but only lasted for 1 minute. The earthquake started many fires that burned for days and destroyed around 500 city blocks. The earthquake could be felt from Los Angeles to southern Oregon, and in central Nevada. This earthquake was caused by the transform plate boundary from the pacific and North American plates. The 2 plates rubbed against each other creating the earthquake. (decodedscience.org).
This causes the ground to shake either not that hard or vigorously. What some folks don’t know is that there happens to be many earthquakes every day just we do not happen to feel them as much. Other earthquakes are huge and have a big impact.
Did you know in 1906 an earthquake with a 7.1 on the Richter scale hit San Francisco? Not only that the damages were huge, the fire resulted from the earthquake burned down twenty-eight thousand buildings alone! But, the earthquake made around two hundred and twenty-five thousand residents homeless which was more than half the amount of residents in San Francisco at the time. Also, if we presume that there were four people in a house then that’s fifty-six thousand two hundred and twenty-five housing that's been demolished, oh you might have noticed, but that is just a 7.1 earthquake which isn’t even the strongest earthquake to hit the world! Now here is an interesting question, what makes these earthquakes so dangerous? Or rather how does earthquake destroy things anyway because you know that earthquakes are just the shifting of the earth's crust.
According to Brillinger (2011), earthquakes were recorded after happening to get an earthquake statistics. Earthquakes may be large or small, serious or trivial; however, the higher the magnitude, the greater the damage to a particular location and the surrounding area. Earthquakes can also create other natural disasters, like tsunamis and volcanic eruptions, which bring more dangerous disasters than earthquakes. Statistics of earthquakes can be extremely important for it can give governments plans to do rebuilding after earthquakes, can help scientists better detect and anticipate earthquakes, and can provide more information to public to learn about earthquakes. It is helpful to take a look at existed statistics; from the website of US government,
The earthquakes above give a brief glimpse into the importance of analyzing past and present fault configurations. If scientists could make a breakthrough in this area perhaps we could better predict earthquake activity and better prepare ourselves if it is deemed a potential disaster is looming.
The San Francisco Earthquake was one of the most devastating earthquakes that ever took place. On April 18, 1906 at approximately 5:13 a.m, unexpected shaking occured. What was taking place was deeper than imagination, and thousands of people wouldn’t allow their brain to believe the disaster that was in motion. The earthquake was so widely spreaded, even other cities were affected.
The most common cause of earthquakes is movement along faults. Earth’s crust is divided into tectonic plates, which grind past each other at fault boundaries. As tectonic plates move,
GeoCosmo is a non-profit research institute devoted to understanding and formalising the field of pre-earthquake science. The team comprises of a number of multidisciplinary and highly accomplished scientists whose mission is to understand pre-earthquake science with the goal of establishing a true global earthquake forecast system that could save billions of dollars and thousands of lives each year (GeoCosmo, 2015). NASA scientist, Dr. Friedemann Freund, is the chairman of GeoCosmo’s science team and was propelled into earthquake science when he discovered his theory of positive holes. Although pre-earthquake science has been deemed inherently impossible (Kagan, 1997; Geller, 1997), Freund has proposed and tested a number of theories that
Earthquakes are a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust. You can’t know when or how much the damage of the shock will be. I think that predicting earthquakes is a bad science because of how often and not they happen.
The amplitude of the ground motion appear due to the lines that occur caused by the pendulum. Many series of earthquakes accident happened across the world and killed thousand of people. Therefore it made more mechanical devices were created.
Where are earthquakes and volcanoes found? Volcanoes and earthquakes have been known to man for thousands of years, but until fairly recently their distribution on the globe was thought of as totally haphazard with each event an isolated phenomenon. Yet, if the positioning of the world’s volcanoes is considered, it can be seen that most volcanoes are situated within several hundred kilometres of the sea, and moreover, that the regions of volcanic activity are concentrated into several girdles or bands circling the Earth. Most notable amongst these are the so-called “Ring of Fire” surrounding the Pacific Ocean (see figure 1), and the more tenuous and disjointed line running down the centre of the Atlantic Ocean. Throughout geological history, igneous activity has been restricted in the same way, as studies of ancient igneous rocks show.
Earthquakes, they destroy, kill, and demolish. Earthquakes have been recorded for a long time. Records have been and always will continue to be recorded for centuries. Earthquakes are recorded by instruments called seismographs. The recording that they make is called a seismogram. These drum sized tubes of decades of earthquakes are more than likely stored in science labs. Earthquakes however, are the releasing of stored energy from plate tectonics. Plate tectonics is the study of 7 massive pieces of rock called continents. They build up energy from pressurized rock that is pushed against each other. When it releases it is like ripples in the water but those ripples are about 10 times the size, plus the waves can go through the earth and hit outer parts of the earth on the other side. Yet, because of different types of materials, the waves will never pass straight through the earth. The thing that powers plate tectonics is convection currents.
