10. Banqiao Dam Failure, 1975
The Banqiao Dam was built in order to hold back around 12 inches of rainfall each day. However, in August 1975, those who created the dam would realize it wasn’t enough. During this time a storm came, caused by a collision between a cold front and Super Typhoon Nina, that brought heavy rains. The rain was so heavy that 7.46 inches fell every hour. This added up to about 41.7 inches of rain each day. The dam failed because of sedimentation blockage and 15.738 billion tons of water was realized within the next few days. Waves up to 23 feet high rushed down streets at 31mph and destroyed everything. After the water settled down, over 231,000 people were dead.



9. Haiyuan Earthquake, 1920
Standing as the 4th deadliest earthquake of all time, the Haiyuan earthquake was catastrophic. Seven provinces were affected by the disaster. On December 16, 1920, a 7.8 earthquake hit Ningxia, China. For three years after the earthquake, aftershocks continued. In just Haiyuan County, more than 73,000 people were killed. The earthquake also caused landslides and large ground cracks, especially close to the epicenter of the earthquake. The earthquake was so strong that some rivers became dammed and others changed courses. Most of the homes and buildings were destroyed. Over 200,000 people were killed because of the natural disaster.

8. Tangshan Earthquake, 1976
The Tangshan earthquake happened on July 28, 1976. It is said to be the 20th century’s largest earthquake. The epicenter of the earthquake was located in Tangshan, which is located in Hebei, China. The city was industrial and had about one million people living in it. The disaster struck early in the morning and lasted 10 seconds or so. It has been said that the earthquake was 7.8-8.2 magnitude. Not only did the earthquake kill, but the 7.8 magnitude aftershock increased the number of deaths.The earthquake was said to first have killed 655,000 people, but the number has been decreased to about 255,000 people.

7. Antakya (Antioch) Earthquake, 565 A.D.
The Antakya earthquake occurred in 565 A.D. Not much is known of this hurricane. It was said to have hit on May 20. It left damage ranging between 1-24 million dollars. The earthquake caused about 250,000 deaths.


6. Indian Ocean Earthquake/Tsunami, 2004
On December 26, 2004, a day after Christmas, and undersea earthquake struck, with its epicenter off the coast of Sumatra, Indonesia. The earthquake occurred because of the subduction that was caused by many tsunamis along the Indian Ocean. Through the earthquake hit many different places, it was most felt in India, Sri Lanka, Indonesia, and Thailand. This is the second largest earthquake recorded, reaching a magnitude of 9.1-9.3. It lasted between 8-10 minutes, and was so severe that the entire planet vibrated and other earthquakes were caused, such as those in Alaska. The earthquake and tsunami caused over 225,000 deaths.

5. India Cyclone, 1839
In 1839, an extremely large cyclone hit Coringa, India. It happened on November 25 when a 40-foot storm surge that was caused by a cyclone completely ruined a city. It wiped out everything that it came into contact to. Sadly, the city was never really rebuilt, 20,000 vessels that were docked in the city were destroyed. Over 300,000 people were dead once the storm surge went down.


4. Bhola Cyclone, 1970
The Bhola Cyclone hit East Pakistan, now known as Bangladesh on November 12, 1970. It stands as the deadliest cyclone to ever have been recorded. Strong winds hit the region at 115mph and the storm was said to have reached the strength of a Category 3 hurricane. However, it wasn’t the winds that killed. Most of those who lost their lives during this natural disaster were killed because of the storm surge. It is said that up to 500,000 people were killed because of the storm surge that brought heavy rain and caused flooding in many areas.

3. Shaanxi Earthquake, 1556
The Shaanxi earthquake stands as the deadliest earthquake ever. On February 14, 1556, an earthquake hit China. Its epicenter was in the Wei River Valley, and as many as 97 counties in places such as Henan, Shaanxi, Hebei, Anhui, and others were affected. In Huaxian, every building that stood was ruined and more than half of the people that lived there were killed. Some statistics show that some counties have up to 60% of their population killed. In all, more than 830,000 people died from the Shaanxi earthquake. Studies have shown that the earthquake’s magnitude was somewhere around 8. Because it was so strong, aftershocks were felt for nearly half a year later.


2. Yellow River Flood, 1887
The Yellow River, which is located in China, is extremely prone to flooding. In 1887, the Yellow River flooded and completely devastated about 50,000 square miles of land. The flood is said to have killed between 900,000-2,000,000 people. Farmers that lived and planted near the river had built small dikes that were, at one point, able to hold back water if it rained. However, the heavy rain that came much too quickly overpowered the dikes and the river flooded.


1. Central China Floods, 1931
Occurring in 1931, the Central China Floods is said to be the deadliest natural disaster that has ever been recorded. It has since been called the greatest disaster to visit China. After a long drought, China was hit by seven cyclones, which brought inches and inches of rain. During the Central China Flood, three different rivers flooded-over, and up to 4 million people were killed because of the floods. Though there were dams built to hold back water in the Yangzte, Yellow, and Huai rivers, they were either poorly built or much too small.
