The world around us often happens with many strange and beautiful natural phenomena, but sometimes they make us scared and can cause a lot of damage to people. Even if you are good at physics and know the nature of various phenomena, you cannot help but be surprised to witness the amazing phenomena nature creates. Have you ever seen an iridescent cloud, dragon scale cloud or a black circle in the sky like a UFO? Let's find out with Toplist the scariest natural phenomena on earth!
1 False Sun Phenomenon
The pseudo-sun can appear as a blob of light to the left or right of the sun, 22° and at the same distance on the horizon as the Sun, in an icy halo. They can be seen anywhere in the world in any season, but they are not always clear or bright. The pseudo-sun is most visible when the sun is low.
The pseudo-sun phenomenon occurs when sunlight overhead passes through ice crystals in the air. In addition to the real Sun at the center, observers also see reflections on the sides. This phenomenon occurs when the temperature is lower than -30 degrees Celsius, the air has a lot of water vapor and ice crystals.
The halo is seen when the Sun is near the horizon, on the same horizontal plane as the observer and the ice crystals. When light passes through the ice crystal, it is bent at an angle of about 22 degrees before being reflected back to the eye.

2 Fire tornado phenomenon
With a length of 10m to 50m, the fire vortex is formed by the unique air temperature and forms a flow with enough force to uproot a tree up to 17m tall. Fire tornadoes can also originate from large fires that lead to a lot of damage to people and property. Although humans rarely witness this strange phenomenon, in fact, they are more common than we think. Because they often appear at the center of intense wildfires, they are not easily seen.
Like many dust whirlwinds commonly seen on sunny days in the southwestern desert region, fire whirlwinds occur when a disproportionately hot patch of land releases a plume of hot air. But while the dust vortex finds its source of heat from the sun, the fire vortex arises from the hot spot of previous wildfires.
Hot air plumes form in a very small area of the ground and they begin to rise rapidly, drawing in the surrounding air like a vacuum cleaner. Then they twist together, looking like a whirlwind.” As the swirling wind gets higher and draws the fire upwards, its diameter begins to shrink, the spin speed gets faster, like a figure skater pulling in his limbs to speed up a ball. rotation.

3 Migration of monarch butterflies
The monarch butterfly migration is the rarest phenomenon in the world. Black-orange monarch butterflies congregate in the mountains of Mexico. They gathered over an area of about 10 acres after flying 3,400 miles from the US. In winter, butterflies fly from the United States through Canada to the mountains west of Mexico City. Unfortunately, in recent years, the number of monarch butterflies has declined drastically.
The image of thousands of monarch butterflies migrating every year looks scary, but it also creates vivid and beautiful pictures. In fact, monarch butterflies have migrations like birds from the north to the south. Biologists say the annual migration of the monarch butterfly from North America to Mexico is an activity that's been going on for millions of years, determined by a pattern of genes passed down across individual species. this butterfly.

4 Phenomenon of lightning strikes
Lightning appears to be an electrical discharge caused by clouds that are positively charged to the ground. Usually the places where lightning occurs are places where the ground is raised, because now the distance between the "two poles" of the ground and the clouds is closer. Lightning strikes often occur on stormy or rainy days. Sometimes they hit densely populated areas and cause great damage to people and property.
Lightning is a complex meteorological phenomenon. Understand the nature of the process of formation and impact of lightning on constructions, such as buildings, warehouses, yards, columns, radio towers, broadcasting, and power lines power, telecommunications lines, telephone lines, internet, coaxial cables, antennas, from which we can take effective measures to prevent lightning.

5 Fire rainbow phenomenon
A fire rainbow (Circumhorizontal arc) is a colorful halo that appears across the sky, also known as the Circumhorizontal arc. When seen in the sky, this colorful halo looks almost like a rainbow. The image of a bright fire rainbow in the sky was recorded by Malaysians and shared widely on social networks. This phenomenon has also occurred in many countries around the world. Many social media users believe that this fire rainbow is a harbinger of the apocalypse or an impending terrible disaster.
However, according to scientists, a fire rainbow crossing the sky is actually an optical phenomenon. The phenomenon, scientifically known as circumhorizontal arc, usually occurs in cirrus or cirrus clouds. Circumhorizontal arc is the result of sunlight shining through ice crystals but it can also be born under moonlight in rarer cases.
According to the Mother Nature Network, this optical phenomenon forms from the refraction of sunlight, sometimes the Moon, through ice crystals suspended in the air. The Sun must then be at a very high position, about 58 degrees above the horizon or higher

6 Bubble Cloud Phenomenon
Bubble clouds are a perfect product of nature, and also completely harmless, a meteorological phenomenon also known as mammatus clouds. Mammatus clouds are always accompanied by strong thunderstorms that can occur during the summer, and are a sign of large amounts of water vapor being held in the air. Each of its "droplets" can be up to 1 mile in diameter. They are also almost opaque, making the clouds appear palpable.
The "cloud balls" that make up this magnificent scene are called "mamatus clouds" and are extremely rare because they are only created at medium altitude and are reflected by sunlight. "They look very strange, especially when they are seen so clearly. These clouds will be seen more brightly when the sunset shines on them, creating beautiful colors." But clouds will create strange shapes like balls completely dependent on temperature and humidity, sometimes the telltale sign of thunder or tornado appearing in the sky.

7 Tsunami
Tsunami, this is an extremely scary natural phenomenon. Tsunamis are actually giant tidal waves generated by earthquakes or volcanic eruptions on the seabed. In 2004, an earthquake and tsunami in the Indian Ocean claimed the lives of about 280,000 people, making it one of the deadliest natural disasters in modern history.
Tsunamis can form when the seafloor suddenly deforms vertically, displacing the water above it. Such large longitudinal movements of the Earth's crust can occur at continental plate margins. Earthquakes caused by special plate collisions often produce tsunamis. When an oceanic plate collides with a continental plate, it sometimes causes the continental plate edge to move downward. Finally, too much pressure on the edge of the plate causes it to jump back (snaps back) creating shock waves into the Earth's crust, causing an undersea earthquake, known as an earthquake at sea.

8 Tropical Storm
A tropical cyclone, also known as a tropical cyclone, is a general term used by meteorologists to describe a rapidly rotating storm system characterized by a center of low pressure, strong winds, and cloud structure. Spiral thunderstorms produce heavy rain, originating over tropical or subtropical waters. Tropical cyclones can achieve sustained wind capacity of as little as 74 miles per hour. The strongest wind speed ever recorded was 200 mph (320km/h) during Hurricane Patricia in 2015.
Tropical storm formation is the development and intensification of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclone formation occurs are markedly different from those leading to the formation of mid-latitude storms. Tropical storm formation involves the development of a warm tornado, due to considerable convection in a favorable atmospheric environment.
Tropical cyclones tend to develop in the summer, but have been recorded in most watersheds for most of every month. Climate cycles such as the ENSO and the Madden-Julian oscillation regulate the timing and frequency of tropical cyclone development. There is a limit on tropical storm intensity that is closely related to water temperature along its route. An average of 86 tropical cyclones of tropical storm intensity form each year around the world.

9 Tornado (Tornacle)
Tornadoes develop from a thunderstorm, usually from very strong or super strong thunderstorms, so where there is a strong thunderstorm there can be a tornado, but fortunately it is very rare. It is also sometimes born from a band of strong gusts of wind (called storm lines) or from a storm. It is thought that when the cold air in the upper layer presses on the hot air below, the hot air will be forced to move up very strongly. But when tornadoes occur over water, there is usually no convection and no temperature difference between layers. Therefore, the cause of tornadoes is still not fully understood by humans.
However, most tornadoes are formed from a particular type of thunderstorm cloud, a charged thunderstorm. A cloud can last for several hours, swirling in an area 10 to 16 kilometers in diameter, moving hundreds of miles and producing countless giant straws. Their origin is a climate with hot air rising and cold air going down.
The first is the interaction process between the upward thunderstorm and the wind. This interaction will cause the hot gas below to move upwards and rotate in the air. This was followed by the development of cold air moving toward the ground on the other side of the storm. The velocity of the downward gas stream can be greater than 160 km/h.

10 Fingers of Death
The brinicle phenomenon, also known as the "finger of death", is an extremely cold mass of salt water that sinks to the sea floor, causing the surrounding seawater to freeze, according to Live Science. Although it was first discovered in the 1960s, it was not until 2011 that the British BBC camera crew recorded this amazing phenomenon at the bottom of the Antarctic sea.
According to Bruno Escribano, a researcher at the Basque Center for Applied Mathematics in Spain, brinicle formation occurs when sea water freezes in the Antarctic and Arctic regions. Salt and other ions in the water are pushed out of the water crystal. The salt-saturated part of the sea does not freeze, but is still scattered inside the ice, with temperatures often below 0 degrees Celsius because high salinity water has a lower freezing point than normal seawater. .
At some point, the ice cracked, the salty sea water escaped. Because of the high density of water, the extremely cold sea water sinks to the bottom of the ocean, freezing the surrounding seawater, gradually forming an ice column nicknamed the "finger of death", or brinicle. When the ice around the brinicle thickens to a certain extent, the ice column can maintain its own cold and stretch out even when it encounters warm water on the seabed.
When the brinicle reaches the bottom of the sea, it immediately destroys all creatures in its path. The affected area can be many square kilometers. In the video, porcupines and starfish slowly freeze when exposed to the cold vapors emanating from the brinicle.
