What is a tsunami and how does it develop? describe one of the several recent tsunamis, either the indian ocean tsunami or more recent japanese tsunami, and its aftermath.

Explanation:  Tsunami is a tidal sea wave, it can be very long and tall, and although called tidal, it does not originate from natural tides, but from a tide that is the result of an earthquake, an underwater volcanic eruption, or other deep tectonic disorders. Tsunami is one of the most dangerous natural disasters, often it can not be predicted timely, that is, registered with monitoring devices, causing enormous damage that is multiple. The great material damage that arises is caused by the enormous force of the giant wave that breaks everything in front of itself. In addition to material damage, unfortunately, during these accidents there are many dead, injured. But these are only primary consequences, since even after the withdrawal of water, epidemics of infectious diseases such as malaria and others can occur. The bodies of dead animals are precisely the source of these infectious diseases. There is also a big problem with drinking water and waterworks, because contaminated water easily reaches. Moreover, financial losses after the tsunami have been great.

There is also a psychological effect that implies even psychological problems in the population after the tsunami. Namely, the people who survived the tsunami and continue live in that area are in constant fear. Some consequences of damage from the previous tsunami are visible for years after, and it serves as a reminder to people that at any moment this can happen again. This creates a sense of helplessness, given that it is a very short time from registration to its appearance on the coast. Anyone who survived the tsunami feels terrible and weakness in front of this force of nature.

The recent tsunami in Japan in June 2019, or the announcement that it could be a tsunami, is a great illustration of the fears caused by the tsunami in Japan in 2011. Namely, in June 2019, after the earthquake, a meteorological agency in Tokyo announced that tsunamis might occur, and a possible wave height of 0.2 to 1.0 meters is possible. But there were very low waves of ten centimeters. People were fleeing to the shelters, sleeping in cartons next to the buildings. However, nothing has happened more seriously than minor injuries in a small number of people.

After the earthquake in 2011 and the appearance of the seabed cracked, an underwater wave was heading for Hawaii and the US, California, and another about an hour and a half after the earthquake, hit the nearby coast of Japan. The height of the wave was about seven meters, swept away cars, ships, houses, and killed people in front of it. In the first storm, 88 people were killed and hundreds disappeared. How important is the time from registration to the occurrence of tsunami, is the fact that the underwater wave that went to Hawaii arrived just in the morning, people have evacuated, lifted protective barricades, and the height of the waves decreases during the journey that lasts longer.
