Why arise waves that arise after the earthquake? Learn how tsunami is made and when alert is released, all know in one click

There is no bus on the waves of the sea. Even on normal days, when high waves arise in the sea, they knock on the edges and make them feel their power. But after a sharp earthquake, the blows in the lower surface of the sea produce a wave that takes a disastrous shape. These tsunami waves are destructive. Before their power, everything is crushed like a straw. Tsunami waves originated in Japan, America’s Hawaii and the Pacific Ocean as a result of a powerful 8.8 scope of 8.8 scope in the Far East of Russia. In this article, we will try to know that what happens after a strong earthquake in the coastal areas that start to rise tsunami waves? When does sea waves start to devastate and when is a tsunami warning issued? When does a tsunami come? Tsunami is a natural disaster. Seismic activities below sea level give rise to tsunami waves. Earthquake causes the tectonic plates to stir and the plates slip. Due to the stir in tectonic plates, the water moves upwards and tsunami waves are formed in the sea. But not every earthquake causes tsunami. It depends on the intensity of the earthquake. After the earthquake, the threat of tsunami is more in countries established on the beach. Especially after a large earthquake (when the intensity of the earthquake is 7 or more), there is a rapid movement in the sea level and large waves are formed in the sea. The causes of tsunamis consist of the Earth’s surface -sustaining dynamic tectonic plates. The tsunami often comes to places where a tectonic plate slides under the other. During the earthquake, when the tension between these plates is suddenly reduced, the sea level slides a few meters above or down within seconds. Imagine putting your hand under the water in the bath quickly. By doing so, a wave in the water will occur that will move to the edges. The same thing happens in the sea, but on a very large scale. This sudden increase in sea level pushes the millions of liters of water on top. Due to gravity, the up raided water tries back to its place. In this process, the energy moves to the water and forms a series of waves that begin to spread in all four directions from the middle of the earthquake. Tsunami waves differ from normal sea waves, as their wavelengths are very long and the velocity of these waves is very fast. They run at a speed of 500 to 1000 km / h. The Tsunami warning system monitors earthquakes and marine activities. Like an earthquake, a tsunami cannot be detected in advance. But the Tsunami Warning Center certainly lights in what earthquake can cause tsunami. Experts believe that, along with warning systems, it is very important to be aware of people to avoid tsunamis. How is a tsunami alert? When a powerful earthquake occurs in the sea, the warning centers become vigilant there. After all types of scientific assessment, it is decided in which direction and how much height the waves will go due to vibration in the sea. Different tsunami -warning systems have been created worldwide to detect it. Countries such as the US, Japan and Indonesia in the Pacific, India, Japan and Indonesia are monitoring through this system. Many sensors and equipment are installed in the sea level to measure the surface and pressure of the sea in these areas. What is the Dart system? Deep ocean assessment and reporting of tsunami, ie Dart is a modern technology that seems to be very effective in making an accurate prediction of tsunami. This technique started in 2000. It has a bottom pressure recorder (BRP) in the depth of the sea connected to a device that floats on the surface. If there is an unusual pressure or stir on sea level, the BRP immediately sends data to the Tsunami warning monitoring centers through the satellite. These centers then analyze the data using computers and decide which areas are threatened. What will be the velocity and direction of the waves and how high the waves can rise. Thereafter, warning is sent to the government and citizens of that region. Nowadays, scientists can issue a tsunami warning about an hour in advance thanks to modern technology. Although this estimate is not 100 percent accurate, it has been effective to save people’s lives. As a result of this technology, people living in many coastal countries get the chance to visit safe places on time.
