Today, an earthquake of 8.8 sizes led to Tsunami warnings and evacuations throughout the Pacific before Russia’s Far East coast.
According to the BBC, it is assumed that this earthquake was one of the most powerful ever recorded and milled millions of people in Japan, Russia and Hawaii due to the resulting tsunami.
So far, no deaths have been reported, but buildings have been destroyed and the ports were immersed by this extreme weather event.
What exactly are tsunamis?
According to the National Oceanic and Atmospheric Administration: “A Tsunami is a number of extremely long waves caused by a large and sudden shift of the ocean, usually on an earthquake under or near the sea floor.”
This force then creates waves that “shine in all directions from their source to the outside and sometimes cross entire ocean basins”.
In contrast to the wind-driven waves that we are used to, tsunamis move directly to the surface throughout the Ocean vom.
What causes tsunamis?
According to the US Tsunami warning system, 88% of the tsunamis in the global historical tsunami database were generated by earthquakes or landslides caused by earthquakes.
However, they can also be caused by volcanic activities, landslides under water or even the effects of a large meteorite that, according to National Geographic, falls into an ocean.
What happens when tsunami’s land hit?
While the evacuations may appear such as an extreme measure, the national weather service explains that tsunamis does not have to be record suspected in order to cause permanent damage.
They say: “A tsunami can be very dangerous for life and ownership of coasts. It can produce unusually strong currents, flood land quickly and cause great destruction. The river and the power of water and the debris that are sluggish can destroy boats, vehicles and buildings and other structures; causes and life as tsunami take over the country.
“It takes only six centimeters of moving water to knock an adult and two foot moving water quickly to carry most vehicles away.”
Even if the waves withdraw alarming to the ocean, they can still be incredibly dangerous: “The water can be just as threatening (if not more), as it returns to the sea and take rubble and people with it. Flood and dangerous currents can take days.”
