The 1556 Shaanxi earthquake (Chinese: 华县大地震; pinyin: Huà xiàn dà dìzhèn) or Jiajing earthquake (Chinese: 嘉靖大地震; pinyin: jiājìng dà dìzhèn) 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.

Geography

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. The earthquake also triggered landslides, which contributed to the massive death toll. The rupture occurred during the reign of the Jiajing Emperor of the Ming Dynasty. Therefore, in Chinese historical record, this earthquake is often referred to as the Jiajing Great Earthquake (Chinese: 嘉靖大地震; pinyin: jiā jìng dà dì zhèn).

Modern estimates, based on geological data, give the earthquake a magnitude of approximately 8 on the moment magnitude scale or XI on the Mercalli scale. While it was the deadliest earthquake and the third deadliest natural disaster in history, there have been earthquakes with considerably higher magnitudes.

Following the earthquake, aftershocks continued several times a month for half a year.

In the annals of China it was described in this manner:

In the winter of 1556, an earthquake catastrophe occurred in the Shaanxi and Shanxi Provinces. In our Hua County, various misfortunes took place. Mountains and rivers changed places and roads were destroyed. In some places, the ground suddenly rose up and formed new hills, or it sank abruptly and became new valleys. In other areas, a stream burst out in an instant, or the ground broke and new gullies appeared. Huts, official houses, temples and city walls collapsed all of a sudden.

The earthquake damaged many of the Forest of Stone steles badly. Of the 114 Kaicheng Stone Classics, 40 were broken in the earthquake.

The scholar Qin Keda lived through the earthquake and recorded details. One conclusion he drew was that "at the very beginning of an earthquake, people indoors should not go out immediately. Just crouch down and wait. Even if the nest has collapsed, some eggs may remain intact." This may indicate that many people were killed trying to flee while some who stayed put may have survived.

The shaking reduced the height of the Small Wild Goose Pagoda in Xi'an from 45 meters to 43.4 meters.

Loess caves

Millions of people at the time lived in artificial Loess caves on high cliffs in the area of the Loess Plateau. Loess is the name for the silty soil that windstorms deposited on the plateau over the ages. The soft loess clay had formed over thousands of years due to wind blowing silt into the area from the Gobi Desert. Loess is a highly erosion-prone soil that is susceptible to the forces of wind and water. The Loess Plateau and its dusty soil cover almost all of Shanxi, Shaanxi, and Gansu provinces and parts of others. Much of the population lived in dwellings called yaodongs in these cliffs. This was the major contributing factor to the huge death toll. The earthquake caused landslides, which destroyed the caves.

Cost

The cost of damage done by the earthquake is almost impossible to measure in modern terms. The death toll, however, has been traditionally given as 820,000 to 830,000. The accompanying property damage would have been incalculable – an entire region of inner China had been destroyed and an estimated 60% of the region's population died.

The Black Death: Bubonic Plague

http://world-worst-disasters.blogspot.com/In the early 1330s an outbreak of deadly bubonic plague occurred in China. The bubonic plague mainly affects rodents, but fleas can transmit the disease to people. Once people are infected, they infect others very rapidly. Plague causes fever and a painful swelling of the lymph glands called buboes, which is how it gets its name. The disease also causes spots on the skin that are red at first and then turn black.

Since China was one of the busiest of the world's trading nations, it was only a matter of time before the outbreak of plague in China spread to western Asia and Europe. In October of 1347, several Italian merchant ships returned from a trip to the Black Sea, one of the key links in trade with China. When the ships docked in Sicily, many of those on board were already dying of plague. Within days the disease spread to the city and the surrounding countryside. An eyewitness tells what happened:

"Realizing what a deadly disaster had come to them, the people quickly drove the Italians from their city. But the disease remained, and soon death was everywhere. Fathers abandoned their sick sons. Lawyers refused to come and make out wills for the dying. Friars and nuns were left to care for the sick, and monasteries and convents were soon deserted, as they were stricken, too. Bodies were left in empty houses, and there was no one to give them a Christian burial."

The disease struck and killed people with terrible speed. The Italian writer Boccaccio said its victims often

"ate lunch with their friends and dinner with their ancestors in paradise."

By the following August, the plague had spread as far north as England, where people called it "The Black Death" because of the black spots it produced on the skin. A terrible killer was loose across Europe, and Medieval medicine had nothing to combat it.

In winter the disease seemed to disappear, but only because fleas--which were now helping to carry it from person to person--are dormant then. Each spring, the plague attacked again, killing new victims. After 5 years 25 million people were dead--one-third of Europe's people.

Even when the worst was over, smaller outbreaks continued, not just for years, but for centuries. The survivors lived in constant fear of the plague's return, and the disease did not disappear until the 1600s.

Medieval society never recovered from the results of the plague. So many people had died that there were serious labor shortages all over Europe. This led workers to demand higher wages, but landlords refused those demands. By the end of the 1300s peasant revolts broke out in England, France, Belgium and Italy.

The disease took its toll on the church as well. People throughout Christendom had prayed devoutly for deliverance from the plague. Why hadn't those prayers been answered? A new period of political turmoil and philosophical questioning lay ahead.

Black Death - Disaster Strikes

25 million people died in just under 5 years between 1347 and 1352. Estimated population of Europe from 1000 to 1352.

• 1000 38 million
• 1100 48 million
• 1200 59 million
• 1300 70 million
• 1347 75 million
• 1352 50 million

1887 Yellow River flood

http://world-worst-disasters.blogspot.com/
The 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.

Halifax Explosion

http://world-worst-disasters.blogspot.com/
The Halifax Explosion occurred on Thursday, December 6, 1917, when the city of Halifax, Nova Scotia, Canada, was devastated by the huge detonation of the SS Mont-Blanc, a French cargo ship, fully loaded with wartime explosives, which accidentally collided with the Norwegian SS Imo in "The Narrows" section of the Halifax Harbour. About 2,000 people were killed by debris, fires, or collapsed buildings and it is estimated that over 9,000 people were injured.This is still the world's largest man-made accidental explosion.

While the city of Halifax's North End neighborhood of Richmond suffered the most damage from the explosion, several neighbouring communities and settlements were also affected by the blast.
  1. Dartmouth

  2. Mi'kmaq settlement

  3. Africville

Heroism and rescue efforts

Many individuals, groups and organizations contributed to the rescue and relief in the days, months, and years following the disaster. Specific acts of heroism and bravery by individuals are detailed below.

Vince Coleman (train dispatcher)


The death toll could have been worse if not for the self-sacrifice of an Intercolonial Railway dispatcher, P. Vincent (Vince) Coleman, operating at the Richmond Railway Yards. He and his co-worker learned of the danger from the burning Mont-Blanc from a sailor and began to flee. Coleman remembered, however, that an incoming passenger train from Saint John, New Brunswick was due to arrive at the rail yard within minutes, and he returned to his post to send out urgent telegraph messages to stop the train.

“ Stop trains. Munitions ship on fire. Approaching Pier 6. Goodbye. ”

Coleman's message brought all incoming trains to a halt and was heard by other stations all along the Intercolonial Railway helping railway officials to respond immediately.[19] The Saint John train is believed to have heeded the warning and stopped a safe distance from the blast at Rockingham, saving the lives of about 300 railway passengers. The rescued train was later used to carry injured and homeless survivors to Truro, Nova Scotia. Coleman was killed at his post as the explosion ripped through the city. He is honoured as a hero and fixture in Canadian history, notably being featured in a "Heritage Minute" one-minute movie and a display at the Maritime Museum of the Atlantic.

Tug Stella Maris

Towing a string of barges at the time of the collision, the Tug Stella Maris responded immediately to the fire, anchoring its barges and steaming beside the flaming Mont Blanc. The tug's crew began spraying Mont Blanc with their fire hose and were preparing to tow the burning ship away from the city when Mont Blanc exploded. The blast killed 19 of the crew aboard Stella Maris although five miraculously survived when the smashed tug was washed up on the Richmond shore.

Halifax Regional Fire and Emergency

Firemen were among the first to respond to the disaster, rushing to Mont-Blanc to attempt to extinguish the blaze before the explosion even occurred. They also played an instrumental role in regaining control of the devastated city after the blast, with members arriving to assist from across Halifax, and by the end of the day from as far away as Springhill (180 kilometres / 110 miles), Amherst, Nova Scotia (200 kilometres / 120 miles), and Moncton, New Brunswick (260 kilometres / 160 miles), via relief trains.

Halifax's Fire Department at the time comprised 8 fire stations, 122 members (36 of whom were fully employed), 13 apparatus (1 of which was motorized), and roughly 30 horses. West Street's Station 2 was the first to arrive at pier 6 with the crew of the American LaFrance-built Patricia, the first motorized fire engine in Canada.

They were responding to Box 83, the dockyard alarm at the corner of Roome Street and Campbell Road (now Barrington Street), as Mont-Blanc drifted toward its resting place at Pier 6. Although the dockyard alarms were routine for the department, today was different, as North End general storekeeper Constant Upham could see the serious nature of the fire from his home and called surrounding fire stations to advise them. Upham's store was on Campbell Road, directly in view of the burning ship, and as one of the few buildings at the time with a telephone, he placed his call sometime after 8:45 that morning. Despite this warning, none of the firemen knew that the ship carried munitions. It was believed however, that the vessel's crew was still onboard, as West Street's Station 2, Brunswick Street's Station 1, Göttingen Street, and Quinpool Road's Station 5 responded to Upham's call.

Fire Chief Edward P. Condon and Deputy Chief William P. Brunt, were next on the scene, arriving from Brunswick Street in the department's 1911 McLaughlin Roadster. The heat was so overwhelming, no one could look at the inferno. Chief Condon pulled the Box 83 alarm again. In the final moments before the explosion, hoses were being unrolled as the fire spread to the docks. Retired Hoseman John Spruin Sr. was on his way from Brunswick Street in a horse-drawn pumper, and Hoseman John H. E. Duggan was traveling from Isleville Street's Station 7 with another horse-drawn firefighting wagon.

None of the firemen knew the danger that they faced as 9:04 arrived, bringing about the explosion that obliterated the dockyard fire site. Fire Chief Edward Condon and Deputy Chief William Brunt were killed immediately along with the Patricia's crew members: Captain William T. Broderick, Captain G. Michael Maltus, Hoseman Walter Hennessey, and Hoseman Frank Killeen. Teamsters John Spruin and John Duggan were both struck and killed by shrapnel en route to the fire. Their horses were also killed instantly in the blast. Patricia hoseman Frank D. Leahy died on December 31, 1917 from his injuries. Nine members of the Halifax Fire Department lost their lives performing their duty that day.

The only surviving member at the scene was Patricia driver Billy (William) Wells, who was opening a hydrant at the time of the blast. He recounts the event for the Mail Star, October 6, 1967,“ That's when it happened ... The first thing I remember after the explosion was standing quite a distance from the fire engine ... The force of the explosion had blown off all my clothes as well as the muscles from my right arm... ”

It is explained that Billy was standing again as the tsunami came over him. He managed to remain on land.

“ ...After the wave had receded I didn't see anything of the other firemen so made my way to the old magazine on Campbell Road ... The sight was awful ... with people hanging out of windows dead. Some with their heads off, and some thrown onto the overhead telegraph wires ... I was taken to Camp Hill Hospital and lay on the floor for two days waiting for a bed. The doctors and nurses certainly gave me great service ”

Notably, firefighter Albert Brunt also survived the blast, by chance, as he slipped while attempting to jump onto the Patricia as it rounded a corner on its way to the docks.

A new pumper was purchased by the city and arrived just a few days after the explosion. The Patricia was later restored by the American LaFrance company for $6,000, who donated $1,500 to a fund for the families of the firemen. The families of firemen killed in the blast received $1,000 from the city (close to $15,000 in 2007 dollars), with the exception of one, who received $500.

On the 75th anniversary of the Halifax Explosion, December 6, 1992, the Halifax Fire Department erected a monument at the current Station 4, at the corner of Lady Hammond Road and Robie Street, in honour of the fallen members who died fighting the fire on Mont-Blanc.

Bhopal Gas Tragedy - The world's worst industrial disaster

http://world-worst-disasters.blogspot.com/
Burial of an unknown child and this unknown
child has become the icon of the world's worst
industrial disaster, caused by the United States
multinational chemical company, Union Carbide.

The Bhopal disaster or Bhopal Gas Tragedy is the world's worst industrial catastrophe. It occurred on the night of December 2-3, 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India. At that time, UCIL was the Indian subsidiary of the U.S. company Union Carbide Corporation (UCC), which is now a subsidiary of Dow Chemical Company. Around midnight on December 2–3, 1984, there was a leak of methyl isocyanate (MIC) gas and other substances from the plant, resulting in the exposure of over 500,000 people.

Estimates vary on the death toll. The official immediate death toll was 2,259 and the government of Madhya Pradesh has confirmed a total of 3,787 deaths related to the gas release. Other government agencies estimate 15,000 deaths. Others estimate that 8,000 died within the first weeks and that another 8,000 have since died from gas-related diseases. A government affidavit filed in the Supreme Court in 2006 stated that of the 558,125 cases of injury resulting from the disaster, 516,406 (92.5%) were minor, 38,478 (6.8%) were temporary partial disablement while 0.7% (~3,900) were severely and permanently disabled. The government's classification was criticized after the deaths of people who were classed as having minor injuries.

Some 26 years after the gas leak, 390 tons of toxic chemicals abandoned at the UCIL plant continue to leak and pollute the groundwater in the region and affect thousands of Bhopal residents who depend on it, though there is some dispute as to whether the chemicals still stored at the site pose any continuing health hazard.

Over 2 decades since the tragedy, certain civil and criminal cases remain pending in the United States District Court, Manhattan and the District Court of Bhopal, India, against Union Carbide with an Indian arrest warrant also pending against Warren Anderson, CEO of Union Carbide at the time of the disaster. Greenpeace asserts that as the Union Carbide CEO, Warren Anderson knew about a 1982 safety audit of the Bhopal plant, which identified 30 major hazards and that they were not fixed in Bhopal but were fixed at the company's identical plant in the US.

In June 2010, 7 ex-employees, including the former chairman of UCIL, were convicted in Bhopal of causing death by negligence and sentenced to two years imprisonment and a fine of about $2,000 each, the maximum punishment allowed by law. An 8 former employee was also convicted but had died before judgment was passed.
