About 145 thousand - 4 million dead. From 1928 to 1930, China suffered from a severe drought. But at the end of the winter of 1930, severe snowstorms began, and in the spring - incessant torrential rains and thaw, due to which the water level in the Yangtze and Yellow Rivers rose significantly. For example, in the Yangtze River in July alone, the water rose by 70 cm.

As a result, the river overflowed its banks and soon reached the city of Nanjing, which at that time was the capital of China. Many people drowned and died from water-borne infectious diseases such as cholera and typhoid. Cases of cannibalism and infanticide among desperate residents are known.

According to Chinese sources, about 145,000 people died as a result of the flood, at the same time, Western sources claim that the death toll was from 3.7 million to 4 million.

Counts largest natural disaster in recorded human history.

3. Flooding on the Yellow River, 1887 and 1938

About 900 thousand and 500 thousand dead, respectively. In 1887, heavy rains fell for many days in Henan province, and on September 28, rising water in the Yellow River broke through the dams. Soon, the water reached the city of Zhengzhou, located in this province, and then spread throughout the northern part of China, covering approximately 130,000 square kilometers. Because of the flood, about two million people in China were left homeless, and about 900,000 people died.

And in 1938, a flood on the same river was provoked by the Nationalist government in Central China at the start of the Sino-Japanese War. This was done in order to stop the Japanese troops advancing rapidly into the central part of China. The flood has subsequently been called "the largest act of environmental warfare in history".

Thus, in June 1938, the Japanese took control of the entire northern part of China, and on June 6 they captured Kaifeng, the capital of Henan province, and threatened to capture Zhengzhou, which was located near the intersection of important railways Beijing-Guangzhou and Lianyungang-Xi'an. If the Japanese army succeeded in doing this, such large Chinese cities as Wuhan and Xi'an would be under threat.

In order to prevent this, the Chinese government in Central China decided to open dams on the Yellow River near the city of Zhengzhou. Water flooded the provinces of Henan, Anhui and Jiangsu adjacent to the river.

The floods destroyed thousands of square kilometers of agricultural land and many villages. Several million people became refugees. According to China's initial figures, about 800,000 people drowned. However, nowadays researchers studying the archives of the disaster claim that many less people- about 400 - 500 thousand.

Interestingly, the value of this Chinese government strategy has been questioned. Since, according to some reports, the Japanese troops at that time were far from the flooded areas. Although their attack on Zhengzhou was thwarted, the Japanese took Wuhan in October.

At least 100 thousand dead. On Saturday, November 5, 1530, on the day of St. Felix de Valois, most of Flanders, the historical region of the Netherlands, and the province of Zeeland were washed away. Researchers believe that more than 100 thousand people died. Subsequently, the day when the disaster occurred was called Evil Saturday.

5 Burchardy's Flood, 1634

About 8-15 thousand dead. On the night of October 11/12, 1634, Germany and Denmark were flooded as a result of a storm surge caused by hurricane winds. This night in several places along the coast North Sea dams broke, water flooded the coastal towns and communities of North Frisia.

According to various estimates, from 8 to 15 thousand people died during the flood.

6. The flood of St. Mary Magdalene, 1342

Several thousand. In July 1342, on the feast day of the myrrh-bearing Mary Magdalene (the Catholic and Lutheran churches celebrate it on July 22), the largest recorded flood in Central Europe occurred.

On this day, the waters of the rivers Rhine, Mosel, Main, Danube, Weser, Werra, Unstrut, Elbe, Vltava and their tributaries flooded the surrounding lands. Many cities such as Cologne, Mainz, Frankfurt am Main, Würzburg, Regensburg, Passau and Vienna were severely damaged.

According to the researchers of this disaster, after a long hot and dry period, heavy rains followed for several days in a row. As a result, about half of the average annual precipitation fell. And since the extremely dry soil could not quickly absorb such an amount of water, surface runoff flooded large areas of the territories. Many buildings were destroyed and thousands of people died. And although total number the dead are unknown, it is believed that about 6 thousand people drowned in the Danube region alone.

In addition, the next summer was wet and cold, so the population was left without a harvest and suffered greatly from hunger. And to everything else, the plague pandemic that took place in the middle of the XIV century in Asia, Europe, North Africa and the island of Greenland (the Black Death), reached its peak in 1348-1350, taking the lives of at least a third of the population of Central Europe.

Illustration of the Black Death, 1411:

History remembers several of the most terrible floods; such natural disasters have also occurred on the territory of Russia, including in St. Petersburg. Several devastating floods occurred in the 20th century.

The worst floods in history

In historical chronicles, one can read about the many severe floods that claimed several hundred thousand human lives. Due to the fact that such natural disasters occur unexpectedly, people are unprepared for them.

Some floods are due to flooding of rivers, bursting of dams, incessant rains, oceanic earthquakes and tsunamis. It is known about the floods that were provoked by people intentionally.

Flood of Saint Mary Magdalene

One of the most devastating floods occurred in 1342. It is considered the largest in Central Europe. Several rivers came out of their banks at once: the Rhine, Weser, Main, Mosel, Werra, Elbe, etc. Having flooded the surrounding lands, the water harmed such large European cities as Cologne, Passau, Vienna, Regensburg, Frankfurt am Main.

The reason was the heavy rains that had been going on for several days. The exact number of those who drowned is unknown, we can say that there were several thousand people. This natural disaster was called the flood of St. Mary Magdalene.

Flood Burchardi

More than eight thousand human lives were claimed by the flood that occurred in 1634 in Denmark and Germany. Due to the hurricane wind, a storm surge of water began, which led to the breakthrough of the dam in several places at once off the coast of the North Sea.


The communities of North Frisia and many coastal towns were flooded. This flood is called the Burchardi flood.

Floods on the Yellow River

As you know, the Yellow River is one of the most capricious rivers in China. It is famous for its frequent floods, and more than once its waters have claimed many human lives. The largest floods of the Yellow River occurred in 1887 and 1938.


In 1887, after heavy rains there have been multiple dam failures. Due to flooding, almost two million people lost their homes, nine hundred thousand people died. In 1938, the Nationalist government was provoked by a flood to stop Japanese troops from advancing on China. Many villages were destroyed, thousands of hectares of agricultural land were destroyed, almost five hundred thousand people drowned, millions became refugees.

The most terrible floods of the twentieth century

In the 20th century, unfortunately, there were also floods. One of them happened in China in 1931 on a river called the Yangtze. According to rough estimates, about four million people died. This flood after the Flood is considered the most severe. Four million houses were demolished, three hundred thousand square kilometers were covered with water.

In 1970, a severe flood occurred in the Ganges Delta in India. It claimed the lives of five hundred thousand people. It was caused by the waters of the Kosi River and torrential monsoon rains. By breaking the dam, the waters of Kosi changed course and flooded a vast region that had never before been subject to flooding.


In 1927, a flood occurred in America, called the "Great". The waters of the Mississippi overflowed due to heavy rains. Flooding affected the territory of ten states, reaching a depth of ten meters in some places. In order not to flood New Orleans, it was decided to blow up a dam near the city. As a result, other territories were flooded. About five hundred thousand people died.


At the end of April 1991, the devastating cyclone Marian raised a nine-meter wave off the coast of Bangladesh. The result of the flood was the death of one hundred and forty thousand people. Lands flooded with salt water became unsuitable for agriculture for many years.

Floods in St. Petersburg

St. Petersburg suffered from floods quite often. The city was flooded at least three hundred and thirty times. In different areas, you can see commemorative plaques on houses showing the water level. There are about twenty such tablets.

In 1691, even before the foundation of St. Petersburg, when the territory of the city was under the Swedes, it was also flooded by the waters of the Neva. This is evidenced by the Swedish chronicles, according to which the water level in the river rose to a mark of seven hundred and sixty-two centimeters.


Most terrible flood happened in 1824. According to various estimates, from two hundred to six hundred thousand citizens died as a result. It is known that the water level in the Neva has risen by more than four meters. Many houses were destroyed and flooded. Before the flood, heavy rain began, followed by a sharp rise in water.

The worst flood in the world - the Flood: myth or reality

Not only the Bible tells about the Flood, many peoples living in almost all parts of the planet have similar descriptions of the terrible flood. The flood can be read in the myths of the Indians of California, it is told in ancient Mexican manuscripts, the myths of the Canadian Indians. It is known about the Japanese "variant" of the flood. Quite rarely, manuscripts found in the interior of Africa and Asia, which are located at a considerable distance from the oceans and seas, report about it.


It can be concluded that many legends about the flood are associated with some local phenomena that led to a sharp rise in the water level. Scientists express several versions of the occurrence of a powerful flood. Most likely the so-called global flood took place in different parts of the Earth, was in each region its own and on different continents had its own causes.

6. The flood of St. Mary Magdalene, 1342
Several thousand. In July 1342, on the feast day of the myrrh-bearing Mary Magdalene (the Catholic and Lutheran churches celebrate it on July 22), the largest recorded flood in Central Europe occurred.

On this day, the waters of the rivers Rhine, Mosel, Main, Danube, Weser, Werra, Unstrut, Elbe, Vltava and their tributaries flooded the surrounding lands. Many cities such as Cologne, Mainz, Frankfurt am Main, Würzburg, Regensburg, Passau and Vienna were severely damaged.
Danube river in Regensburg, Germany:

According to the researchers of this disaster, after a long hot and dry period, heavy rains followed for several days in a row. As a result, about half of the average annual precipitation fell. And since the extremely dry soil could not quickly absorb such an amount of water, surface runoff flooded large areas of the territories. Many buildings were destroyed and thousands of people died. And although the total number of deaths is unknown, it is believed that about 6 thousand people drowned in the Danube region alone.
In addition, the next summer was wet and cold, so the population was left without a harvest and suffered greatly from hunger. And to everything else, the plague pandemic that took place in the middle of the XIV century in Asia, Europe, North Africa and the island of Greenland (Black Death), reached its peak in 1348-1350, taking the lives of at least a third of the population of Central Europe.
