Earthquakes
Over the past five hundred years, Earthquake activity has increased tremendously. Even in 2015 Irving, Texas has had at least eighty nine earthquakes! Earthquakes are formed underground when tectonic plates begin to rub against one another. Earthquakes are starting to form and happen constantly because of many different reasons. One example being, fracking, which is the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc., so as to force open existing fissures and extract oil or gas. When contractors frack they create manmade Earthquakes.

At 5:12 AM on April 18, 1906, the Great 1906 San Francisco Earthquake occurred. The rupture was about two hundred and ninety six miles. According to eyewitness …show more content…

The earthquake rupture started approximately twenty five kilometers beneath the surface, with its core about six miles (ten kilometers) east of the mouth of College Fiord and seventy five miles (one hundred and twenty kilometers) east of Anchorage. The earthquake lasted approximately four and half minutes and is the most powerful recorded earthquake in U.S. history. It is also the second largest earthquake ever recorded, next to the magnitude 9.5 earthquake in Chile in 1960. The aftershocks were about two hundred and fifty kilometers wide and they extended eight hundred kilometers. The main shock occurred on the fault boundary between the Pacific and North American plates. Over a thousand aftershocks were recorded after the main shock. On the first day the earthquake occurred over eleven aftershocks with magnitudes greater than 6.0 took place. In the weeks following nine occurred. Throughout the rest of the year smaller aftershock occurred periodically. Because of the earthquake, four hundred million dollars was recorded in damages. Major structures were destroyed throughout the cities in Alaska. The four and a half minutes of shaking also caused landslides and avalanches. Over one hundred and thirty thousand square kilometers received the most damage. Around one hundred and thirty one people were killed in total. One hundred and fifteen …show more content…

During this earthquake approximately one thousand six hundred and fifty five people were killed, three thousand were injured, two million were left homeless, and five hundred and fifty million dollars of damages in southern Chile was reported; the tsunami which occurred after the earthquake caused sixty one deaths, seventy five million dollars’ worth of damages in Hawaii; one hundred and thirty eight deaths and fifty million dollars’ worth of damages in Japan; thirty two dead and missing in the Philippines; and five hundred thousand dollars’ worth of damages to the west coast of the United

Modulus: 1X Earth Science Name: Leroy (CHAN CHUNG YIU) Staff member in charge: Tim Dempster ID:2183820C Title: The April 1906 San Francisco Earthquake Introduction On April 18th, 1906, one of the worst natural disasters happened in the US history. This first major disaster which is recorded in human history with photography, has a 7.8 magnitude(USGS,2013).A subduction of the Pacific plates pulled into the San Andreas plates with the north-west direction, causing a 400 km(ECSC) rupture line. Huge energy is radiated out of the epicenter which was just 2 miles of west San Francisco, the intensity of the shaking nearly wiped out most of the buildings and structures with a duration of 110s(ECSC), affected around 370,000 square meters(NZH,1906).

The earthquakes intensity was measured at a magnitude of 7.9 on the present Richter scale (The Great 1906, 4). This earthquake was an extremely vigorous magnitude that would have killed approximately fifthteen hundred to forty five hundred people and injure fifty thousand (House, 51). This was not the first earthquake in San Francisco. 1864, 1898, and 1900 were years of earthquakes striking but not as strong as 1906 (San Francisco of 1906, 1). Ten million California residents who lived closely from the major fault lines could have been in endangered in many extreme ways. (House, 56).

The last Cascadia earthquake in the 1700s gave the people of that time five minutes to prepare before it happened. If this coming earthquake is similar then the citizens of the Pacific Northwest will not have a long warning before it hits. Cities will be underwater across the coast and the people caught in the chaos can only hope and pray that they will make it out alive. Across Oregon alone it is estimated to be over a million buildings in ruins. FEMA estimates that search-and-rescue teams will be sent out across a hundred thousand square miles of land and across four hundred and fifty-three miles off the coastline.

Although the report released by Lawson provided insight about earthquake occurrence, it cannot help scientists and geologists to accurately predict when the next earthquake will occur. However, with advanced monitoring systems and computing power may help in better preparation of future earthquakes. The 1906 San Francisco earthquake brought geologists and scientists together and led to an understanding of earthquakes; how they occur, why they occur and how the world can prevent and manage such disasters in

A cloud of dust was visible from the rubble of the collapsed buildings. The only light in the city was the fire burning in the Marina district. Sirens blared from every direction. The shock was responsible for 63 deaths, 3,757 injuries and left 3,000-12,000 people homeless.

You stand in the middle of a normally bustling street but the ground beneath you feels like violent waves. Buildings crumble down around you and violent flames lash out from burning houses. Screams of terror echo through the air as families run barefoot into the streets, you watch with terrified eyes as the Golden City crashes to the ground around you. This is what it would be like during the great San Francisco Earthquake of 1906. The disaster took place at 5:12am on April 18th and took the lives of roughly 3,000 people.

By the way one of the American author, Thomas Sowell, had said that “All thing are the same except for the differences and different except for the similarities” and that it true however both of them are the top strongest earthquakes but they are some different and similarity between them. Valdivia earthquake and Alaska earthquake are happened in America.

The earthquake was also followed by multiple aftershocks. However, as many as 1.5 million people were displaced. The country, long known to be at high risk for earthquakes, has enforced strict building codes in urban areas, which helped to limit the amount of damage in these areas. But buildings and homes in poorer areas—many built with adobe—did not fare as well. Chile's electricity grids, communication, and transportation systems were badly damaged, severely hampering rescue and aid efforts.

These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.

The 2010 earthquake was caused by a transform boundary fault known as the Enriquillo-Plantain Garden fault (Bruno, N.d.). The epicenter of the earthquake was SW of Port of Prince and estimated at a depth of 13 KM (DesRoches et al./2011). The earthquake was measured at a magnitude 7 on the Richter scale (Bruno, N.d.) and the country experienced two more devastating aftershocks about twenty minutes later measured at a 6 and 5.7 (DesRoches et al./2011). Large earthquakes, such as the one that hit Haiti, tend to be violent and can shake the ground for a long time (Smith, Petley/2009).

The Haiti earthquake last 2010 provided a terrifying major earthquake that cause a population loss of between 100,000 and 316,000. Aside from its weaknesses preparations for such disasters, the aid sector was also unequipped for the urban challenge. Other large-scale disasters such as the Tohoku earthquake in Japan last 2011 and tsunami, and the Typhoon Haiyan in the Philippines last 2013 as well as other numerous smaller disasters triggered by natural phenomena reinforce the increasing threat of such

The earthquake was a magnitude 9.0 off the coasts of Japan that occurred at 2:46pm on Friday 11 March 2011, which triggered a powerful tsunami that reached the height up to 10.4 meters. A Japanese National Police Agency reported 15,889 deaths, 6,152 injured, and 2,601 people missing, 127,290 buildings totally collapse, 272,788 buildings half collapse, and another 747,989 buildings partially damaged.
