5:12 a.m., Wednesday, April 18, 1906, one of the most devastating earthquakes in the history of the United States hit the heavily populated city of San Francisco, California. This violent earthquake caused extensive and expensive damage and deaths across the city and even resulted in a fire that raged throughout the city for four full days after the earthquake. While the exact casualty tall is uncertain modern scientist estimate the death toll to be around 3,000 people with rough 25,000 left without a home(_____________3________________). However, all was not lost, from the rubble and ashes of San Francisco scientists, seismologist, and geologists alike were able to make improvements upon earthquake technology and better define what causes
This earthquake caused 60 deaths, 9,000 people injured. Causing the San Fernando Valley a total pile of destruction (TheAtlantic.com). What was actually the main cause of the Northridge earthquake? Why did the Northridge earthquake caused so many destruction? The earthquake happened because of the movement from the San Andreas Fault (u-s-history.com) .This little movement from the tectonic caused big things such as earthquake, but what exactly is San Andreas Fault?
Helens or Louwella-Clough is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It last erupted on July 10, 2008, but is most famous for its eruption in 1980 which killed more than 57 people and killed thousand of animals. It cause about a billion US dollars to repair. Mount St. Helens is famous for its 1980 eruption. It is one of the world’s most active stratovolcanoes.
(National Geographic News, 2015). The tsunami resulted in at least 227,000 fatalities, destroyed 141,000 houses and took away the livelihood of more than 600,000 people. (The Bolton Council of Mosques, 2015). The force of the earthquake was thought to have had the energy of 23,000 Hiroshima-type atomic bombs. The cause of the earthquake and
A tsunami event that occurred in 2004 , called the Boxing Day Tsunami, displaced 1.7 million and injured half a million of souls. A total of 230,000 people were killed (Telegraph,2014). Tsunamis are giant ocean waves that are triggered by an earthquakes or volcanic eruptions. These ocean waves will grow in height as they travel inland, due to the depth of the ocean decreasing. The world responded with donations and relief efforts to countries affected which included Indonesia, Thailand, Somalia, Sri Lanka, Burma and Maldives.
The sections will slip, relieving the pressure and creating an earthquake as the energy that was held in the two sections is transferred into seismic waves, also known as an earthquake (Alvarez, et al., 2014). Conclusion The largest earthquake ever recorded on the rector scale is the Great Chilean Earthquake. At some time in the past as some point there could have been a larger earthquake, however the technology did not exist, it would not have been recorded. With the Great Chilean Earthquake there devastating effects of landscape, loss of building and home and the disastrous amount of people that lost their life. Had the technology been available in the 1960’s, the death toll would have been significant reduced and potentially they could have predicted this disastrous
The monumental nature of Atlantis’s destruction is described in several phases. It is said that each phase consisted of ground shaking tremors, eruptions, or an onslaught of waves which all lead up to the complete destruction of the utopia. Although it is hard to believe, these exact circumstances happened to the Minoan people. First, there were several earthquakes preceding the eruptions of the most powerful volcano in history (“Fall of the Minoans"). The Thera eruption was four times more powerful than the Krakatoa eruption of 1988 (Nardo 74).
Since the epicentre of the quake was on land no Tsunami occurred. The event was followed by aftershocks for about 17 months. One of the major and devastating aftershock was Christchurch earthquake. At 12.51 pm NZDT on 22 February 2011 an earthquake of magnitude 6.3 again struck the Canterbury region of South island, New Zealand, but this time the earthquake was centred 2 kilometres west of the port town of Lyttelton and 10 kilometres south-east of the centre of Christchurch, New Zealand's second most populous city. The earthquake caused widespread damage to the life and ecology.
Valdivia, Chile, 22 May 1960 (9.5) This earthquake killed 1655 people, injured 3000 . It caused US$550 million damage in Chile, while the tsunami that it spawned caused deaths and damage as far away as Hawaii, Japan and the Philippines. The 'rupture zone ' of the quake was more than 1000 km long. Two days after the initial quake, the nearby volcano Puyehue erupted, sending ash and steam up to 6 km into the atmosphere over a period of several weeks.
According to National Geographic, these waves can reach heights up to 35 meters, and are mostly the aftereffects of earthquakes. “Most tsunamis, about 80 percent, happen within the Pacific Ocean’s “Ring of Fire,” a geologically active area where tectonic shifts make volcanoes and earthquakes common.” said one of the scientists working with National Geographic(7). Above the mantle of the earth, there is a layer made of tectonic plates, which fall into either the continental or oceanic category. They move and occasionally meet, which creates stress between the rocks. Due to this stress, the plates bend and break in order to release the elastic energy stored inside them.
August 29th, 2005, a category 5 hurricane made land fall along the United States Gulf Coast. Hurricane Katrina is considered to be one of the most destructive hurricanes the U.S. has ever incurred; displacing hundreds of thousands from their homes throughout Louisiana, Mississippi, and Alabama. Consequently the U.S. economy was greatly impacted from the desolation that Hurricane Katrina inflicted. Katrina stretched over 400 miles across with wind speeds up to 100-140 mph; more than 2,000 lives were lost and over 90,000 square miles of the U.S. were affected. After the storm thousands were left stranded in attics and on roofs for days until rescue missions arrived.
Over fifty people died from flooding and mudslides. Sandy became even stronger as it moved from Hispaniola to Cuba. Fifty-five thousand people were evacuated. The storm hit Santiago de Compostela, Cuba’s second largest city. Sandy became the deadliest hurricane to hit Cuba.
Mount St. Helens is a massive active volcano right in the heart of Washington. During 1980 from March-May the volcano showed signs of an impending eruption. On March 27, a preliminary thick cloud of steam shot out of the volcano, throughout the following months a visually apparent bulge begin to form on the side of the mountain. On May 18, the volcano erupted with a lateral blast that was the largest in recorded history, and produced a 5.1 magnitude earthquake. The earthquake initiated a flank collapse that caused a landslide producing enough debris to fill 1 million Olympic sized swimming pools.
After the quake the country was going through a case of mass hysteria. The quake in Haiti had a high magnitude of 7.0 one of the highest ever recorded. The earthquake hit near the town of Leogane about 16 miles southwest from Haiti’s capital Port-au- Prince. The quake hit at 4:53 PM, with aftershocks that came soon after. Then there
Greater and stronger earthquakes, greater than magnitude 7, happen more than once per month. Huge earthquakes, magnitude 8 and higher, occur about once a year. Most earthquakes occur along the edge of the oceanic and continental plates (“How Often Do Earthquakes Occur?”). The world’s largest earthquake with an instrumentally documented magnitude occurred on May 22, 1960 near Valdivia, in southern Chile. It was assigned a magnitude of 9.5 by the United States Geological Survey.
