Tsunami warnings have been issued in two parts of Japan, what measures have been taken by the local

As for the topography of Japan, everyone must be aware that they are surrounded by the sea and the terrain is narrow. It is surrounded by volcanoes and tsunamis throughout the year, and there is a high probability of large-scale tsunamis and volcanic eruptions.

After the tsunami warning was issued, the local authorities immediately took measures to clear the situation and warn the local residents, and asked the residents to prepare the necessary daily necessities and food at home as much as possible, so as not to cause water, electricity and food cuts after a dangerous situation.

After the tsunami warning was issued, it also attracted the attention of many climate experts, who said that the tsunami may affect the global environmental situation, and extreme weather conditions may occur in various places, including extremely cold weather and hurricanes, etc., so the surrounding countries must pay attention to such situations and prepare for the arrival of the tsunami. <>

It can be seen that the power of human beings is too small in the face of nature, and in daily life, we may feel that we are in balance with nature, and even we once tolerated nature and cared for ecological balance.

In fact, our survival depends on the favor of nature. Our overconsumption and unrestrained destruction of nature is likely to have very serious consequences for ourselves, and this tsunami warning is a common alarm for humanity around the world.

Next, I believe that we will rethink our view of nature and try to repair our relationship with nature and protect the environment.

Everyone is responsible, and this sentence will be deeply planted in our hearts. To take the ideology of equality.

to deal with all things in the world.

The Japan Meteorological Agency issued a tsunami warning for coastal areas in Fukushima and Miyagi prefectures. The epicenter was located at north latitude and east longitude. The depth of the epicenter is 60 km, and the magnitude is magnitude.

Fukushima and Miyagi reached a magnitude of 6 at their maximum**, and the tremors were felt strongly in Tokyo, which was far away from the epicenter. Make every effort to gather information about.

Residents of the coastal areas of Fukushima and Miyagi Prefecture are reminded to stay away from the coast and remain vigilant. The Tohoku Shinkansen train derailed between Fukushima Station and Shiraishizao Station with some of the carriages tilted. A fire alarm was raised in the No. 5 turbine room of the Fukushima Daiichi Nuclear Power Plant, and the fire department did not find a fire after going to the scene.

The spent fuel pool cooling pumps of units 1 and 3 of the Fukushima No. 2 nuclear power plant stopped working. The drone is equipped with a camera, and the images from the route are sent to the city disaster information center to grasp the damage and whether there are any people who have not been evacuated in time.

In eastern Japan, including two employees in Sendai City, employees and firefighters in coastal areas were killed by the tsunami while guiding shelters. In order to respond to disasters, the use of the latest technologies such as drones, which do not rely on human labor, may be promoted in the future. In order to prevent communication interruption in the event of a disaster, it is used to operate the machine body.

The city says the move is the first of its kind in the world. For tsunami warnings and large tsunami warnings, the drone will automatically activate from the base in the coastal area of the city and fly along the coastline of 7 kilometers to the north and south.

There are popular fishing and surfing spots on the route, and no one has a chance to use the loudspeaker to call "A large tsunami warning has been issued." This is Sendai City. The drone is equipped with a camera that sends images along the route to the city's disaster information center to grasp the disaster situation and whether there are people who have not been evacuated in time.

Sendai City has made efforts to import a number of aircraft. While the speakers are installed outdoors in coastal areas, there are also areas where sound cannot reach. For the sake of safety, we want to make maximum use of the latest technology to respond to disasters.

Emergency dispatch of rescue personnel, evacuation of local people, reinforcement of doors and windows of houses, maintenance of power supply systems, preparation of daily necessities and other measures were effective in dealing with the tsunami.

First, call on the public not to go to the beach, second, pack up important finances, third, be vigilant at all times, fourth, evacuate from the seaside dwellings, and fifth, set up temporary tents.

Tsunamis are a very dangerous natural disaster.

Whenever a tsunami comes, coastal cities are hit by a tsunami. In Japan, the Japan Meteorological Agency says that tsunamis will hit repeatedly, and most people, especially those living in coastal cities, are very worried about the news of such tsunamis. So what are the causes of tsunamis?

The earth's plates are constantly moving, although they are invisible to the naked eye, but it is moving every minute, and sometimes several plates collide with each other, which will cause huge friction. And this kind of friction will cause the seabed **, once the seabed is launched**, then it will cause a tsunami. But most of the world's tectonic plates move, but in some places the movement is not very obvious, so it cannot cause a tsunami, and in some places, the movement is very obvious, so it causes a tsunami.

As long as there is movement in the earth's crust.

When the seabed erupts, the tsunami will cover the surrounding cities with seawater, so some countries have also carried out some measures to prevent the tsunami. <>

In some places, there are always some extreme weather, sometimes thunderstorms, or some storms, which can also cause tsunamis. The storm will roll up the water on the sea, forming a huge tsunami, at this time, the surrounding coastal cities will basically be submerged, so for some surrounding cities, they will raise their own water embankments to prevent the tsunami from flooding the city. And because of global warming.

The reason for extreme weather.

It is becoming more and more frequent, so natural disasters such as tsunamis may occur more often in the future. <>

If you encounter a tsunami, you must evacuate to a safe area as soon as possible, because the tsunami is very fast, and a person's legs may not be able to run through the tsunami. If you can't evacuate in time, be sure to start running to a higher place, and remember to avoid rolling rocks in high places to avoid being hit by rolling stones.

A tsunami is a catastrophic wave that travels at a high speed of 600-1,000 kilometers per hour to 10,000 to 20,000 kilometers, often setting off 10-40 meters of rough waves. In the aftermath of the tsunami, the beach was a mess, littered with broken wood and dead bodies. It can be seen that the power of the tsunami is devastating.

So what caused a tsunami? What are the common causes of tsunamis?

A tsunami is a catastrophic wave.

How the tsunami was caused.

A tsunami is a catastrophic wave that is usually caused by a seabed** with an epicenter within 50 kilometers of the ocean floor and above the Richter scale. Tsunamis can also be caused by landslides or volcanic eruptions underwater or along the coast. After a shock, the ** wave travels a long distance in an ever-expanding circle on the surface of the sea, just like the wave produced by a pebble falling into a shallow pool.

The tsunami wavelength is greater than the maximum depth of the ocean, and the orbital motion is not much hindered near the ocean floor, and the wave can propagate regardless of the depth of the ocean.

The speed at which a tsunami travels is directly proportional to the depth of the water in which it travels.

In the Pacific Ocean, tsunamis, which generally travel at speeds ranging from two to three hundred kilometers per hour to more than 1,000 kilometers per hour. Tsunamis do not cause damage in the deep oceans, and it is difficult for ships under sail to detect such fluctuations. When a tsunami occurs, the safer it is to the outer sea.

Once a tsunami enters the continental shelf, waves can be devastating due to a sharp increase in wave height of 20 to 30 metres due to a sharp decrease in depth.

The causes of tsunamis fall into three categories: tsunamis, volcanic tsunamis, and landslide tsunamis. A tsunami is a strong disturbance of seawater caused by a sharp rise and fall in the topography of the seabed.

There are two forms of mechanism: "descending" tsunamis and "uplifting" tsunamis.

The speed at which a tsunami travels is directly proportional to the depth of the water in which it travels.

Descending type "tsunami": some tectonic ** causes a large area of sharp decline in the submarine crust, the sea water first swells to the space of sudden staggered subsidence, and there is a large-scale accumulation of seawater above it, when the inrushing seawater encounters resistance on the seabed, it turns back to the sea surface to produce compression waves, forming long waves and large waves, and propagating and spreading around, this descending type of tsunami formed by the movement of the submarine crust is the first to show abnormal low tide phenomenon on the coast. The 1960 Chile** tsunami was of this type.

Uplift "Tsunami": Some tectonic structures ** cause a large-scale sharp rise of the seafloor crust, and the seawater also rises with the uplift area, and there is a large-scale accumulation of seawater above the uplift area, under the action of gravity, the seawater must maintain an equipotential surface to achieve relative equilibrium, so the seawater spreads from the wave source area to the surroundings, forming a turbulent wave. The tsunami waves formed by the movement of the seafloor crust in this uplifted type first appear as an abnormal high tide phenomenon on the coast.

On May 26, 1983, the tsunami caused by the Sea of Central Japan** was of this type.

There are many reasons for tsunamis, but the main reason is that Japan is located in the Pacific Rim volcanic zone, and the crustal activity is relatively frequent, and whenever the ** zone begins to move and the shock wave generated by the movement of rocks, it will cause damage to things on the ground, so it is common to cause tsunamis and tsunami.

The constant movement of the earth's crustal plates, the deterioration of the global environment, global warming, the occurrence of severe natural bad weather, and the strong attack of cold and humid air are all possible causes of tsunamis.

The ocean surface has happened**. Intense ocean current effects. Sea levels are rising. Volcanic eruptions. Storms at sea level. The above five causes can lead to the occurrence of tsunamis.

The main causes of tsunamis are**, volcanic eruptions, landslides, cosmic effects, global warming, destruction of nature, these factors can trigger tsunamis.

Affected by the eruption of Tonga's submarine volcano, Japan issued a tsunami warning in the early hours of the morning, which is also the first tsunami warning issued by Japan since November 2016, and the tsunami has been observed in more than 10 places such as Kagoshima Prefecture, Iwate Prefecture, Kochi Prefecture and Fukushima Prefecture in Japan, and many places have seen the trough rise causing fishing boats to capsize or be washed away, and the Japan Meteorological Agency has also warned that the tsunami will arrive repeatedly, calling on local residents to choose to continue to evacuate, and the tsunami has little impact on our country.

Because the location of the submarine volcanic eruption in Tonga is far away from our country, although the tsunami is very large, but it has not affected our country, so it will not have much impact, but it is understood that the eruption of the Tangjia volcano not only caused a tsunami, but more serious may lead to global cooling, if the global weather is abnormal, then it will affect the production of crops, and more serious will lead to food shortages around the world, and even cause a food crisis, which is what we need to continue to pay attention to.

Generally, before the tsunami, it can be observed in advance, so we must respond to the call of the first to choose continuous evacuation, and must not go out to sea during the tsunami, which is completely to treat their lives as child's play, if they are fishermen at sea, they must fix their boats, and then go to a safe and open place on land, and wait until they think that the tsunami has disappeared before they can return to their place of residence, which is also responsible for their own life safety.

After the eruption of the Tangjia volcano, the United States, Canada and other countries have issued a tsunami warning, and a tsunami wave has also been detected along the coast of China, but the maximum tsunami wave amplitude is about 20 cm, so it has not caused a catastrophic impact on the coast of China, but for the occurrence of the tsunami, we must pay attention to it in advance, prepare in advance, and also learn some safe escape knowledge, so even if we encounter a tsunami in the future, we can retreat in time to ensure the safety of our lives and property.

Volcanic eruptions of different sizes have different impacts on the global community. According to foreign media reports, the eruptions of small volcanoes generally only affect the environment and climate of local areas, because the volcanic ash they produce generally cannot reach the stratosphere, and the volcanic ash will soon settle to the surface. However, it can lead to local air pollution.

It will have an impact on our country, and the Ministry of Natural Resources of China expects that the central test results will be analyzed, and a tsunami wave was detected along the coast of China on the 16th, of which Zhejiang is the largest tsunami wave of about minus 20 cm, which caused a catastrophic ideal to China's coast.

It may have a certain impact, because Japan is very close to China, so we need to protect in advance.

The impact on our country is not large, and it will not affect the coastal areas of our country.

According to the Japan Meteorological Agency, an earthquake with a magnitude of ** occurred in the sea near Fukushima Prefecture in Japan on the 16th, and a tsunami warning has been issued locally, and people living in relevant areas should leave the coastal area as soon as possible. A tsunami is a catastrophic wave that is usually underwater or on the ground** and is in danger of triggering a tsunami if it is relatively close to the sea. Living by the sea, it is a very pleasant thing to be able to face the sea directly, living by the sea can be **sea view, and because the seaside is generally relatively far away from the city, so in terms of noise compared to the city, the noise index is very low, and then you can swim often when you live by the sea, the sea water contains a lot of minerals, and regular swimming can not only improve ** Finally, living by the sea is far away from the hustle and bustle of the city, and there is less pollution, so the air is very fresh, and there are many advantages to living by the sea, but there are also disadvantages to pay attention to the following things.

One is because you live by the sea, relatively speaking, the humidity is relatively large, if you live here, then you must pay attention to your rheumatic diseases in time, and have regular check-ups. <>

Second, the seaside residence Haifeng will bring in the steam of seawater, so the humidity will be relatively large, drying clothes, if there is no big sun, it is not easy to dry, dry furniture and house furnishings in the high humidity air for a long time, the public will be easy to corrode and deform, especially metal products, it is easy to rust.

The third is that life will not be very convenient, because living by the sea, if the surrounding facilities are not very complete, the cost of living will be relatively high, the facilities are incomplete, and the most direct impact is that life will not be very convenient. <>

Fourth, we should pay attention to the secondary disasters caused by **, after the ground, the secondary disasters usually collapse houses, and the secondary disasters on the seaside are usually tsunamis, because under the influence of the tsunami, the sea surface fluctuates greatly and will form higher sea waves, which will then directly threaten the residents living by the sea.
