Researchers say that this event was not the largest in the history of our planet...

The strongest shift of the ground of the earth: at a time shifted so much dirt that would be enough to cover the metropolis

Researchers say that this event was not the largest in the history of our planet, but became special - the entire amount of sediment was transferred at a time. Earth's history has more than 4. 5 billion years, and during this time our planet has experienced many dangerous and large -scale events. One of them happened about 60,000 years ago near the coast of North-Western Africa, when a huge avalanche collapsed under the water column, IFLSCIENCE. It is known that it all started with 1.

5 cubic kilometer of precipitation that rolled along the Agadir canyon - one of the largest in the world. When this amount of sediment rolled 450 kilometers of the underwater canyon, it increased 100 times - eventually the incredible 162 cubic kilometers of material were shifted. For comparison, this would be enough to completely cover one metropolis with dirt. In focus. Technology has appeared its Telegram channel.

However, researchers say that in the history of underwater landslides there were more events: for example, Storegga landslides shifted the total volume more than 20 times greater than the event Bed 5. But in the latter there was something amazing: Other events, as a rule, occurred in stages, and only BED 5 moved all the mass at a time.

According to a researcher from the National Oceanographic Center of Great Britain, Dr. James Hunt, the event Bed 5 is a underwater shift of the soil, which mostly turned from a large liaison to a diluted sediment. This precipitate rolled through the entire canyon, and then down through the underwater pools coming out of the canyon. The event paved the path of tens of meters deep and many kilometers wide, displacing more and more mass. Extreme erosion that led to incredible swelling.

According to Hunt, there are two hypotheses about how such shifts will eventually be delayed on the seabed. According to one of them, they are deposited by the turbulence of the liquid, according to the other - their movement is similar to the flow of garbage. However, scientists now believe that there is another option. According to what the BED 5 points to, the flows can also move from one state to another.

Researchers say that such events in the history of the planet are actually infrequent: about once every 50,000 years. They do not happen inadvertently: they require sediment accumulation, and researchers believe that this occurs during periods between the glacial period and the planet's melting. According to Dr. Hunt, tsunami will probably be the consequences of such a shift, but researchers are not sure about its scale.

Crucus for the modeling of the scale of the tsunami is the speed of displacement of the soil, as well as the volume of water that is moved. Something that falls into the water, such as shift of soil from the volcanic island to the ocean, can have more serious consequences than a larger underwater shift of the soil that is already under the waves. Researchers also point out that we do not know much about these catastrophic events that occur under the water stricters.
