A. Before the L'Aquila earthquake in 2009 people were starting to prepare for a earthquake but not a 6.3 earthquake. However, there was miscommunication between the scientist and the people of L'Aquila. Since earthquakes are the hardest natural disaster to predict, nothing is always 100 percent accurate. The seismologist involved with the making of predictions did not want to scare the people and make them prepare for an earthquake that was not going to come, when the seismologist were not even postie of the earthquake coming.…
Which generates massive earthquakes every 100 to 150 years. The plate boundary broke of in 2 sections in 1949 - 46. The last earthquake was in 1854, theorized that subduction zone is to relive its accumulated stress. Keiji Doi, Which was and earthquake research institute that lays out entire scenario. Major earthquakes have hit this world really hard.…
Although geologist cannot predict when an earthquake will occur, they can make assumptions based on location and previous earthquake activity if earthquakes will continue in the same area. The records of the 1906 San Francisco earthquake explain why damage…
The amount of monetary damage from an earthquake and the loss of life, depends on the type of soil, the retrofitting of the land, and how dense the population of that city is. In 1989, San Fransisco, California, was hit with a 15-second earthquake; the earthquake was 7.1 in magnitude. The fault of this earthquake was on the San Andres fault line. The damage from this earthquake was very severe, roadways were torn apart, and houses were destroyed. The area of the most damage was built on poor ground conditions, and sandy and loose soil.…

On the 22nd of May, 1960, Chile experienced one of the largest earthquakes recorded to date. The earthquake struck 160km’s off the coast of Southern Chile parallel to the city of Valdivia at 7:11pm. The temblor was the cause of significant damage and loss of life in both Chile and distant Pacific coastal areas. It is believed that the earthquake had a magnitude of 9.5 following a series of foreshocks the previous day. The earthquake was responsible for extreme destruction within Chile and caused nearly half of the buildings in Valdivia to be rendered uninhabitable.…
According to Christopher Scholz and his two colleagues, “The sudden movement of the Earth caused by the abrupt release of accumulated strain along a fault in the interior,” meaning an earthquake is the sudden movement along a fault line, which is where tectonic plates meet. When the plates shift this causes the Earth to shake but when the plates become unrestrained large earthquakes occur. The earthquake is not something that happens in one moment, it is a gradual buildup of pressure in one area that when released can cause large…
Will induced seismicity be a term we hear on a regular basis, or is it just a media trigger word? Due to the lack of scientific facts, Contrary to the media’s…
Unnatural earthquakes have occurred over the last 16 years in Oklahoma due to fracking causing seismic instability in the earth; because Oklahoma’s geography does not normally experience earthquakes, the unnatural disasters are particularly devastating to their buildings which lack the foundation to withstand them. From 1975 to 2008, the U.S. Geological Survey measured, on average, 1 to 3 earthquakes annually in Oklahoma. Once the current fracking boom began in 2009 in Oklahoma, that number spiked to an average 40 earthquakes annually from 2009 to 2013 and they’ve been worsening since. In 2014, Oklahoma experienced over 580 earthquakes of 3.0 magnitude or greater. And to make it worse, a news report by the Chicago Tribune during the month of November 2016, reported that a range between 40 to 50 buildings had been affected by a 5.0 magnitude earthquake during the month of November, which is the third in Oklahoma this year with a magnitude of 5.0 or greater.…
After months of research and still no answer as to how this earthquake could have happened, a fresh pair of scientific eyes started a new investigation. During the course of his investigation, George Plafker confirmed the recent and still developing ideas of plate…
How Geo-processes Change the Surface of the Earth “Volcanologists have identified the existence of more than 40,000 volcanoes on Earth”(1). Volcanoes are not the only factor in the changing of the Earth’s surface. There are multiple reasons for the Earth to change. Geoprocesses including tsunamis, volcanoes, and earthquakes all contribute to affect the Earth and its surface. First, tsunamis produce transformations in the Earth’s surface.…
Yearly, there are fifty to sixty volcanoes erupted. Within the year, two tsunamis devastate, and several million earthquakes befall upon the planet. These are geoprocesses, all of these affect Earth’s surface and the inhabitants thereof. Earth’s surface changes through geoprocesses including volcanoes, earthquakes, and tsunamis.…
An earthquake is the phenomenon that a huge energy suddenly released and appeared in the Earth’s crust when two moved plates slip past one another. The earthquakes usually happen in the convergent boundaries, divergent boundaries and transform boundaries. In the three kinds of boundaries, the convergent boundary often produces the largest magnitude earthquakes. Because when the two plates collide strongly in the convergent boundary, the extreme pressure and the great friction will appear. So the convergent boundary is more likely to have a large magnitude earthquake.…
The aim is to know the nature of these subsoil’s, their dynamic behavior and how these soils resist the earthquake or can amplify the seismic waves and cause considered damages. The selected sites in Nile Delta area are the same sites where H/V spectral ratios were measured (chapter 3). 2-D seismic refraction modeling technique is applied to calculate the number of layers, their thickness, and VP – and SH wave velocities for each layer. The dynamic (elastic) characteristics are calculated to know the physical nature of each layer.…
