The 1931 China floods, or the 1931 Yangtze–Huai River floods, were a series of floods that occurred from June to August 1931 in China, hitting major cities such as Wuhan, Nanjing and beyond, which eventually culminated into a dike breach along Lake Gaoyou on 25 August 1931.

Fatality estimates vary widely. A field survey by the University of Nanking led by John Lossing Buck immediately after the flood found 150,000 people had drowned, and that this number represented less than a quarter of all fatalities during the first 100 days of the flood. The official report found 140,000 drowned and claims that 2 million people died during the flood, having drowned or died from lack of food. A cholera epidemic in the subsequent year, from May 1932, was officially reported to have 31,974 deaths and 100,666 cases. A popular high-end estimate of 3.7 to 4.0 million fatalities enjoys great currency online, helping the 1931 flood to secure its position on sensationalist lists of the world’s deadliest disasters.

Also known as the Great Tangshan earthquake, was a natural disaster resulting from a magnitude 7.6 earthquake that hit the region around Tangshan, Hebei, People's Republic of China on 28 July 1976, at 3:42 in the morning. The maximum intensity of the earthquake was XI (Extreme) on the Mercali scale. In minutes, eighty-five percent of the buildings in Tangshan collapsed or were unusable, all services failed, and most of the highway and railway bridges collapsed or were seriously damaged. At least 242,000 people died (some have said three times that), making this the third (or possibly second) deadliest earthquake in recorded history. The lack of warning and foreshocks, in contrast to the earlier 1975 Haicheng earthquake, was a principal factor in the large number of casualties.

242, 000 people were killed and as many as 7,00,000 were injured.

Another reason why the death toll had increased to an extraordinary amount was because of the aftershocks that took place 16 hours after the first quake. The aftershocks were recorded to be as high as 7.1 on the Richter Scale, which not only hampered the rescue efforts but also added to the death toll. The Chinese government had not allowed foreign aid in the city, claiming that they were capable of handling the crisis on their own.

The 1970 Bhola cyclone was a devastating tropical cyclone that struck East Pakistan (present-day Bangladesh) and India's West Bengal on November 11, 1970. It remains the deadliest tropical cyclone ever recorded and one of the world's deadliest natural disasters. At least 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. Bhola was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season

The Bhola cyclone is the deadliest tropical cyclone on record and also one of the deadliest natural disasters in modern history. A comparable number of people died as a result of the 1976 Tangshan earthquake, the 2010 Haiti earthquake and the 2004 Indian Ocean earthquake

In January 1971, the coldest period of the year in East Pakistan, the National Relief and Rehabilitation Committee, headed by the editor of Ittefaq, said thousands of survivors from the storm were "passing their days under [the] open sky". A spokesman said families who were made homeless by the cyclone were receiving up to 250 rupees (US$55 dollars in 1971; equivalent to $341 in 2018) to rebuild, but that resources were scarce and he feared the survivors would "eat the cash"

A catastrophic magnitude 7.0 Mw earthquake struck Haiti at 16:53 local time (21:53 UTC) on Tuesday, 12 January 2010. The epicenter was near the town of Léogâne, Ouest department, approximately 25 kilometres (16 mi) west of Port-au-Prince, Haiti's capital

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.Death toll estimates range from 100,000 to about 160,000 or more

In mid February 2010, the Haitian government reported the death toll to have reached 230,000.[ However, an investigation by Radio Netherlands has questioned the official death toll, reporting an estimate of 92,000 deaths as being a more realistic figure

The earthquake struck in the most populated area of the country. The International Federation of Red Cross and Red Crescent Societies estimated that as many as 3 million people had been affected by the quake. In mid February 2010, the Haitian government reported the death toll to have reached 230,000

It was an undersea megathrust earthquake that registered a magnitude of 9.1–9.3 Mw, reaching a Mercalli intensity up to IX in certain areas. The earthquake was caused by a rupture along the fault between the Burma Plate and the Indian Plate.

A series of massive tsunami waves grew up to 30 m (100 ft) high once heading inland, after being created by the underwater seismic activity offshore. Communities along the surrounding coasts of the Indian Ocean were devastated, and the tsunamis killed an estimated 227,898 people in 14 countries, making it one of the deadliest natural disasters in recorded history

The direct results caused major disruptions to living conditions and commerce in coastal provinces of surrounded countries, including Aceh (Indonesia), Sri Lanka, Tamil Nadu (India) and Khao Lak (Thailand). Banda Aceh reported the largest number of deaths.

The earthquake was the third-largest ever recorded, the largest in the 21st century and had the longest duration of faulting ever observed, between eight and ten minutes.It caused the planet to vibrate as much as 10 mm (0.4 in), and also remotely triggered earthquakes as far away as Alaska.

After tidal waves hit the region. Survivors grimly buried or burnt their dead Monday in southern India as the death toll rose to at least 6,597 with thousands more missing amid warnings of a return of the killer tsunami.

India has deployed 4,000 troops and a fleet of ships and aircraft carrying hundreds of tonnes of relief material for survivors of the killer tidal waves, Indian Defence Minister Pranab Mukherjee said Wednesday.
