In its history, humanity has experienced several unforgettable catastrophic disasters. Throughout the ages, there have been various types of catastrophic disasters that have befallen humans. Humanity has experienced disasters ranging from locust plagues to years without sunlight. Summarized from various sources, here is a list of catastrophic natural disasters whose causes are still a mystery to this day.

"After that, many people reported sightings of lost and deceased spirits due to the tsunami. There were also quite a few cases of possession. These sightings and possessions are likely a result of collective trauma and guilt among the survivors. However, many believe that these sightings are real evidence of paranormal activity."

It all started with the construction of the Three Gorges Dam in Hubei, China in the 1990s, which became controversial. When an earthquake with a magnitude of 7.8 on the Richter scale hit Sichuan Province, the dam was blamed as the cause. Despite bringing significant benefits such as electricity and flood control, the dam has caused a lot of ecological damage.

Scientists speculate that this sinkhole is caused by permafrost or frozen soil layer melting. The melting of this permafrost coincides with the expansion of methane gas, creating a collapsed mound of layered ice and soil. However, until now scientists have not been able to determine the exact cause.

If the star explodes at a close enough distance, the Gamma rays produced can destroy the Earth in an instant. Strangely, in 2013, scientists discovered evidence that the Earth had been hit by a Gamma ray burst in the 8th century. Scientists found traces of Gamma rays after studying the rings of Japanese cedar trees dating back to the year 775.

The incident between December 1811 and February 1812 reportedly caused the flow of the Mississippi River to reverse. Scientists explained that the strange phenomenon was liquefaction or soil movement. According to them, the soil was lifted due to a powerful earthquake, making it appear as if the river changed direction temporarily. However, what is still unclear is the actual cause of the earthquake.

However, the Sun's sound produces radiation in the 19th century, as in the Carrington event in September 1859. The Sun's sound at that time became a large geomagnetic storm that caused power outages and disruptions to telegrams. This event is still mysterious because there is still much to be understood about the event and about the Sun's sound in general.

With an estimated explosion of 10 megatons or more, its power exceeds that of the atomic bomb in Japan. Although the cause is suspected to be an asteroid, some people doubt this story. Because an asteroid collision would certainly leave a crater. They suspect that the event in Tunguska was caused by a natural gas explosion or the collision of two comets.
