6.5 million structures More than 6.5 million structures have collapsed and another 23 million have been damaged as a result of the earthquake. This makes it the world's most devastating natural disaster since the Great Depression.
The number of deaths resulting from the earthquake is estimated to be around 87,000 people. The majority of these deaths were due to collapsing buildings with many more likely to have died accidentally while making their way out of the devastated area.
Almost all schools in the affected region were destroyed and there were no reports of any students surviving the earthquake with their teachers.
Many hospitals were also damaged or destroyed and there were no reports of any survivors from them.
Finally, there are also reports of prisoners escaping from jail in Chengdu after its walls were demolished by the earthquake. However, there are no reports of anyone else being held at the sites where these escapes occurred.
Chengdu is one of China's most important cities and has nearly six million people living in its built-up area. It's location near the epicenter of the earthquake made it particularly vulnerable to damage.
In fact, according to some reports, 90% of the city center was destroyed.
According to national officials, this catastrophic 7.0 earthquake killed over 300,000 people, wounded another 300,000, and displaced and homeless over 1.3 million people (GOH 2010). This enormous earthquake destroyed over 105,000 dwellings and damaged another 208,000. The majority of these structures were small houses built for economic survival after 1990.
The earthquake also caused a large number of schools to collapse, killing 497 students and teachers. Many hospitals were also damaged or destroyed, including the main hospital in Cap-Haïtien, which was reduced to rubble.
However, the government reports that only 1,636 people died in the capital city of Port-au-Prince, although it is estimated that 10,000 people may have been killed in total. The discrepancy between the death toll in Port-au-Prince and the rest of the country is due to a lack of coordination between governmental agencies responsible for disaster response.
In addition to the human cost, the earthquake also caused an environmental disaster by causing mass deforestation in southern Haiti. Before the earthquake, more than 80 percent of Haitians lived in rural areas with little or no industrial development. As a result, most homes were made up of simple concrete blocks without any kind of safety equipment such as fire walls or insulation.
According to a US Geological Survey simulation of a magnitude 7.8 earthquake in Southern California, 50 weak concrete structures housing 7,500 people might fully or partially collapse, while five high-rise steel buildings containing 5,000 people could completely collapse. A total of 130 people might be killed.
The risk to life from earthquakes is generally considered to be low compared to other natural disasters. However, because most deaths occur in poorly constructed old buildings, it is possible to save many lives by simply not building cities out of fragile materials such as cement and wood. In addition, the development of new technology that can withstand severe shaking will reduce damage and death in future earthquakes.
In conclusion, an earthquake of a certain size will kill hundreds if not thousands of people due to collapsing buildings.
Buildings fall as a result of earthquakes for the following reasons: most buildings are not built/made earthquake-proof. Earthquake vibrations They fall apart owing to weak foundations, subpar internal materials, and insufficient steel.
Approximately 200 of these "soft-story" buildings collapsed in the Northridge earthquake, including one that killed 16 people. The majority of the deaths resulted from falling objects during the collapse of multi-story buildings.
The Northridge earthquake occurred at 2:31 a.m. on January 17, 1994. It was a strike-slip fault quake, which means that it was caused by differences in loading on opposite sides of the fault. The rupture on the north side of the fault moved toward the south city center, while the south side moved away from it. The distance between these two points is called the slip factor. In this case, the slip factor was about 10 miles.
Soft-story buildings are generally constructed with thick walls for stability but lack an independent support system for the interior floors. Therefore, if the exterior wall begins to show signs of damage, such as cracks, employees should not enter the building until it has been inspected by a structural engineer. If the engineer finds no immediate danger, then people should be allowed back into the building.
In the case of the Northridge building collapse, workers were entering the building through its front entrance when the first sign of trouble appeared. A crack ran across the third floor landing, and some bricks fell out of the wall.
According to reports from September 1999, 120,000 poorly designed dwellings were damaged beyond repair, and roughly 20,000 structures fell, causing more than 250,000 people to become homeless as a result of the earthquake.
Additionally, 13 schools and three hospitals were destroyed. The total cost of the disaster was estimated at $150 million.
The majority of the victims were Turkish citizens who lived in housing built before 1946 for ethnic Turks living in what is now called Turkey. However, there were also citizens of other countries including Syria, Iran, and Iraq who resided there.
In addition, there are reports of Chinese students being killed in this earthquake. The official number is 36 but unconfirmed reports say the death toll may be as high as 500.
Finally, there is a report of a Japanese school collapsing with the loss of 40 children. However, this figure cannot be confirmed and has not been verified by any other source.
In conclusion, the Izmit Earthquake caused damage to approximately 220,000 buildings and left about 50,000 people homeless.
Approximately 122,000 buildings were entirely destroyed, 283,000 were severely damaged, and another 748,000 were slightly damaged. This makes the tsunami one of the most destructive natural disasters in history.
The final toll was estimated at 187,000 buildings destroyed or damaged. About seven million people were affected by the tsunami.
The number of buildings that were destroyed or severely damaged lies between 125,000 and 150,000. This is made up of 122,000 entirely destroyed buildings and 3,000 severely damaged buildings. An additional 10,000 buildings were heavily damaged (defined as having more than 20% of its contents lost).
Even years after the earthquake and tsunami have subsided, many areas still suffer from power outages, making it difficult for local officials to conduct thorough damage assessments.
It can take months or even years before all the damage caused by the tsunami is discovered. In some cases, buildings that were evacuated because of the threat of damage from the tsunami are later found to be OK. In other cases, such as with the nuclear plant in Fukushima, Japan has been forced to dismantle parts of its infrastructure because they were found to be too dangerous to remain active.
