Ten deadliest natural disasters

A quick intro: I have collected some info and made a selection about 10 the most deadliest natural disasters. I was considering mostly Wikipedia and Encarta because I believe they have the most accurate information.

 

 

 

 

 

 

 

 

10.  Haiti earthquake (January 12, 2010)

The 2010 Haiti earthquake (Haitian Creole: Tranblemanntè 2010 nan pe Ayiti) was a catastrophic magnitude 7.0 Mw earthquake, with an epicentre near the town of Léogâne, approximately 25 km (16 miles) west of Port-au-Prince, Haiti’s capital. The earthquake occurred at 16:53 local time (21:53 UTC) on Tuesday, 12 January 2010. By 24 January, at least 52 aftershocks measuring 4.5 or greater had been recorded. An estimated three million people were affected by the quake; the Haitian Government reported that an estimated 230,000 people had died, 300,000 had been injured and 1,000,000 made homeless. They also estimated that 250,000 residences and 30,000 commercial buildings had collapsed or were severely damaged.
The Pacific Tsunami Warning Center issued a tsunami warning immediately after the initial quake, but quickly cancelled it. Nearly two weeks later it was reported that the beach of the small fishing town of Petit Paradis was hit by a localised tsunami wave shortly after the earthquake, probably as a result of an underwater slide, and this was later confirmed by researchers. At least three people were swept out to sea by the wave and were reported dead. Witnesses told reporters that the sea first retreated and a "very big wave" followed rapidly, crashing ashore and sweeping boats and debris into the ocean.
Amongst the widespread devastation and damage throughout Port-au-Prince and elsewhere, vital infrastructure necessary to respond to the disaster was severely damaged or destroyed. This included all hospitals in the capital; air, sea, and land transport facilities; and communication systems.

In July, as much as 98% of the rubble from the quake remains uncleared. An estimated 26 cubic yards (20 m3) million remain, making most of the capital impassable. Thousands of bodies remain in the rubble. The number of people in relief camps of tents and tarps since the quake remains at 1.6 million, and almost no transitional housing has been built. Most of the camps have no electricity, running water, or sewage disposal, and the tents are beginning to fall apart. Crime in the camps is widespread, especially against women and girls. Between 23 major charities, $1.1 billion has been collected for Haiti for relief efforts. Two percent of the money has been released. According to a CBS report, $3.1 billion was pledged for humanitarian aid and has paid for field hospitals, plastic tarps, bandages, and food, plus salaries, transportation and upkeep of relief workers.

9. Indian Ocean earthquake and tsunami (December 26, 2004)

The 2004 Indian Ocean earthquake was an undersea megathrust earthquake that occurred at 00:58:53 UTC on December 26, 2004, with an epicentre off the west coast of Sumatra, Indonesia. The quake itself is known by the scientific community as the Sumatra-Andaman earthquake. The resulting tsunami is given various names, including the 2004 Indian Ocean tsunami, Asian Tsunami, Indonesian Tsunami, and Boxing Day Tsunami. The earthquake was caused by subduction and triggered a series of devastating tsunamis along the coasts of most landmasses bordering the Indian Ocean, killing over 230,000 people in fourteen countries, and inundating coastal communities with waves up to 30 meters (100 feet) high. It was one of the deadliest natural disasters in recorded history. Indonesia was the hardest hit, followed by Sri Lanka, India, and Thailand. With a magnitude of between 9.1 and 9.3, it is the second largest earthquake ever recorded on a seismograph. This earthquake had the longest duration of faulting ever observed, between 8.3 and 10 minutes. It caused the entire planet to vibrate as much as 1 cm (0.4 inches) and triggered other earthquakes as far away as Alaska. The plight of the many affected people and countries prompted a widespread humanitarian response. In all, the worldwide community donated more than $7 billion (2004 U.S. dollars) in humanitarian aid. The hypocenter occurred between Simeulue and mainland Indonesia.

The sudden vertical rise of the seabed by several metres during the earthquake displaced massive volumes of water, resulting in a tsunami that struck the coasts of the Indian Ocean. A tsunami which causes damage far away from its source is sometimes called a teletsunami and is much more likely to be produced by vertical motion of the seabed than by horizontal motion.
Despite a lag of up to several hours between the earthquake and the impact of the tsunami, nearly all of the victims were taken completely by surprise. There were no tsunami warning systems in the Indian Ocean to detect tsunamis or to warn the general populace living around the ocean. Tsunami detection is not easy because while a tsunami is in deep water it has little height and a network of sensors is needed to detect it. Setting up the communications infrastructure to issue timely warnings is an even bigger problem, particularly in a relatively poor part of the world.

8. Haiyuan earthquake (December 16, 1920)

1920 Haiyuan earthquake, was an earthquake that occurred on December 16, 1920. The epicenter was 36°30′N 105°42′E / 36.50°N 105.70°E / 36.50; 105.70, in Haiyuan County, Ningxia Province, Republic of China. It was also called the 1920 Gansu earthquake because Ningxia was a part of Gansu Province when the earthquake occurred. The earthquake hit at local time 20:06:53 (GMT 12:06:53), reportedly 7.8 on the Richter magnitude scale, followed by a series of aftershocks for three years. Today’s Chinese media claim the earthquake as of magnitude 8.5, although the scale is not specified. It caused total destruction (XII – the maximum intensity on the Mercalli scale) in the Lijunbu-Haiyuan-Ganyanchi area. Over 73,000 people were killed in Haiyuan County. A landslide buried the village of Sujiahe in Xiji County. More than 30,000 people were killed in Guyuan County. Nearly all the houses collapsed in the cities of Longde and Huining. Damage (VI-X) occurred in 7 provinces and regions, including the major cities of Lanzhou, Taiyuan, Xi’an, Xining and Yinchuan. It was felt from the Yellow Sea to Qinghai (Tsinghai) Province and from Nei Mongol (Inner Mongolia) south to central Sichuan Province.
About 200 km (125 mi) of surface faulting was seen from Lijunbu through Ganyanchi to Jingtai. There were large numbers of landslides and ground cracks throughout the epicentral area. Some rivers were dammed, others changed course. Seiches from this earthquake were observed in 2 lakes and 3 fjords in western Norway.Total casualty was reported as 200,000 in a summary published by the United States Geological Survey (USGS), 240,000 according to Ningxia Daily, a Chinese publication in the current administrative area, and 235,502 according to the Catalog of Damaging Earthquakes in the World (Through 2008) maintained by the International Institute of Seismology and Earthquake Engineering.

7. Tangshan eartquake (July 28, 1976)

The Tangshan Earthquake also known as the Great Tangshan Earthquake, was a natural disaster that occurred on July 28, 1976. It is believed to be the largest earthquake of the 20th century by death toll. The epicenter of the earthquake was near Tangshan in Hebei, People’s Republic of China, an industrial city with approximately one million inhabitants.

The number of deaths initially reported by the Chinese government was 655,000, but this number has since been stated to be around 240,000 to 255,000. A further 164,000 people were recorded as being severely injured. The earthquake came in between a series of political events involving the Communist Party of China. It shook China both literally and figuratively in 1976, which was later labeled a "Year of curse". The earthquake hit in the early morning, at 03:42:53.8 local time (1976 July 27 19:42:53.8 UTC), and lasted for around 15 seconds. Chinese Government’s official sources state 7.8 on the Richter magnitude scale, though some sources listed it as high as 8.2. It was followed by a major 7.8 magnitude aftershock some 16 hours later, increasing the death toll.

6. Antioch earthquake (526)

In 526 during late May, probably between the 20th and the 29th, a major earthquake hit Syria and Antioch, Turkey, killing approximately 250000 people. The earthquake was followed by a fire that destroyed most of the buildings left standing by the earthquake. Damage estimates on the Modified Mercalli scale are; VIII Antioch, VII Dafna & Seleucia Pieria. In the port of Seleucia Pereia an uplift of 0.7–0.8 m has been estimated, and the subsequent silting up of the harbour left it unusable. It was the 3rd most deadly earthquake of all time.

5. India cyclon (November 25, 1839)

A 40-foot storm surge from a huge cyclone that hit Coringa, India on November 25 destroyed 20,00  ships and killed approximately 300,000 people.

4. Bhola cyclone (November 13, 1970)

The 1970 Bhola cyclone was a devastating tropical cyclone that struck East Pakistan (now Bangladesh) and India’s West Bengal on November 12, 1970. It was the deadliest tropical cyclone ever recorded, and one of the deadliest natural disasters in modern times. Up to 500,000 people lost their lives in the storm, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. This cyclone was the sixth cyclonic storm of the 1970 North Indian Ocean cyclone season, and also the season’s strongest, reaching a strength equivalent to a Category 3 hurricane.

The cyclone formed over the central Bay of Bengal on November 8 and travelled north, intensifying as it did so. It reached its peak with winds of 185 km/h (115 mph) on November 12, and made landfall on the coast of East Pakistan that night. The storm surge devastated many of the offshore islands, wiping out villages and destroying crops throughout the region. In the most severely affected Thana, Tazumuddin, over 45% of the population of 167,000 was killed by the storm.

The Pakistani government was severely criticized for its handling of the relief operations following the storm, both by local political leaders in East Pakistan and in the international media. The opposition Awami League gained a landslide victory in the province, and continuing unrest between East Pakistan and the central government triggered the Bangladesh Liberation War, which concluded with the creation of the country of Bangladesh.

3. Shaanxi eartquake (January 23, 1556)

The 1556 Shaanxi earthquake or Jiajing earthquake was a catastrophic earthquake and is also the deadliest earthquake on record, killing approximately 830,000 people in China. It occurred on the morning of 23 January 1556 in Shaanxi, during the Ming Dynasty. More than 97 counties in the provinces of Shaanxi, Shanxi, Henan, Gansu, Hebei, Shandong, Hubei, Hunan, Jiangsu and Anhui were affected. An 840-kilometre (520 mi)-wide area was destroyed, and in some counties 60% of the population was killed. Most of the population in the area at the time lived in yaodongs, artificial caves in loess cliffs, many of which collapsed during the catastrophe with great loss of life.

The Shaanxi earthquake’s epicenter was in the Wei River Valley in Shaanxi Province, near the cities of Huaxian, Weinan and Huayin. In Huaxian, every single building and home was demolished, killing more than half the residents of the city, with a death toll estimated in the tens of thousands. The situation in Weinan and Huayin was similar. In certain areas, 20-metre (66 ft) deep crevices opened in the earth. Destruction and death were everywhere, affecting places as far as 500 kilometres (310 mi) from the epicenter.

2. Yellow River Flood (September, October, 1887)

he 1887 Yellow River flood was a devastating flood on the Yellow River (Huang He) in China. This river is prone to flooding due to the elevated nature of the river, running between dykes above the broad plains surrounding it. The flood that began in September 1887 devastated the area, killing some 900,000 people. It was one of the deadliest natural disasters ever recorded.

For centuries, the farmers living near the Yellow River had built dikes to contain the rising waters, caused by silt accumulation on the riverbed. In 1887, this rising riverbed, coupled with days of heavy rain, overcame the dikes on around 28th September, causing a massive flood. Since there is no international unit with which to measure a flood’s strength it is usually classified by the extent of the damage done,depth of water left and number of casualties.

The waters of the Yellow River are generally thought to have broken through the dikes in Huayankou, near the city of Zhengzhou in Henan province. Owing to the low-lying plains near the area, the flood spread very quickly throughout Northern China, covering an estimated 50,000 square miles, swamping agricultural settlements and commercial centers. After the flood, two million were left homeless. The resulting pandemic and lack of basic essentials claimed as many lives as those lost directly by the flood itself. It was one of the worst floods in history, though the later 1931 Yellow River flood may have killed as many as four million.

1. China floods (July, November, 1931)

The 1931 Central China floods or the Central China floods of 1931 were a series of floods that occurred during the Nanjing decade in the Republic of China era. It is generally considered the deadliest natural disaster ever recorded, and almost certainly the deadliest of the 20th century (when pandemics are discounted) and in China. The human casualties are estimated from 1,345,000 to between 3.7 million to 4 million.

From 1928 to 1930 a long drought preceded the flood. By some accounts abnormal weather over central China began in the winter of late 1930. Heavy snowstorms in the winter were followed by spring thaw/defrost heavy rains that raised the river levels even higher. The rain increased into July and August of 1931. In July alone 7 cyclones hit the region. On average two occur per year.

Chinese sources usually indicate the death toll of the Yangtze river drainage at about 145,000 and affecting 28.5 million, while most western sources place the death toll from the floods at an estimation between 3.7 and 4 million people.

The Yellow River has historically been considered the "Cradle of Chinese Civilization". Major floods in this river generally have catastrophic agricultural, economic and social impact. The Yellow River flood occurred between July and November 1931. Estimates of the number of people killed in the flood generally range from 1 to 2 million. Figures have shown about 1 million people died of drowning. Some listed the Yellow River death toll alone to be as high as 4 million. The river completely inundated 87,000 km2 (20,000,000 acres). It partially inundated 20,000 km2 (5,000,000 acres), and left 80 million people homeless.
