One of the most dangerous disasters is an earthquake.
The scale changes completely depending on the seismic intensity, but large earthquakes can cause tsunamis and are very dangerous.
Is there any good news that an earthquake occurred in Japan?
Recently, there was the Great East Japan Earthquake in 2011.
What a deadly disaster with 16,000 dead!
This time, we will explore the mechanism of such an earthquake and the possibility of an earthquake in Japan in the future.
And if you live in Japan, I will also introduce how to take measures.
How often do earthquakes occur in Japan?
I think some people in your country have a few earthquakes and have never experienced it.
According to measurements by the Japan Meteorological Agency, the number of earthquakes with seismic intensity 1 or more in 2018 is a whopping 2,179 times.
To put it simply, an earthquake occurs somewhere in Japan about six times a day.
However, since it is a shaking that can be felt by people from about the seismic intensity, it is so small that almost no shaking is felt.
It is said that 20% of the world’s earthquakes are occurring in Japan.
Especially in the year of the 2011 Great East Japan Earthquake, there were 10680 earthquakes per year. This year, 30 earthquakes occurred every day.
Earthquakes occur so frequently in Japan. For this reason, earthquake training is conducted in schools and communities in Japan, and everyone knows how to take countermeasures.
However, most of the foreigners do not know about the earthquake.
It’s a very dangerous disaster and I hope it helps prevent injuries and the worst consequences of an earthquake.
I think everyone in the science class is learning about the mechanism of earthquakes, but some of you may have forgotten them, so let’s review them again.
First, there are dozens of plates underground on the earth. You are living on that big bedrock.
They are connected to other plates like puzzles.
And it rests on the mantle doing inside the earth. So, a little, but the plate is moving every year.
They are passing each other, pushing up and down on the opposite board.
There are four plates around Japan, and the plate on the seafloor is heavy because it contains seawater and sinks below the other plate.
At that time, the upper board is also subjected to force, and when it can not withstand, cracks and rebounds occur, causing an earthquake.
To put it simply, when a heavy plate sinks, the other plate also exerts a force. Cracks and recoils occur as if the springs that had been fixed were removed when the force could not withstand. That phenomenon is an earthquake.
Please also see the visuals because it is difficult to understand because the video is also posted.
Possibility of an earthquake in Japan
Earthquakes, unlike other disasters, unlike hurricanes, occur unexpectedly and are very difficult to predict. Therefore, casualties increase.
However, researchers have discovered that large-scale earthquakes occur periodically when studying Japanese history.
Recently, a large-scale earthquake called the Nankai Trough earthquake is said to occur with a 70-0% probability within the next 30 years.
And there is data published by the country that the dead is 300,000.
What should we do if such a big earthquake occurs?
Here is a video about the earthquake distributed by the Japanese government.
That said, many earthquakes have occurred in Japan surprisingly beyond the Nankai Trough. So an earthquake can happen when you are in Japan.
The Great Hanshin Earthquake that occurred in 1995 occurred at 5:46 in the morning. Many people said that most people were buried in rubble when they woke up in the morning while sleeping on futons.
What should I do in such a case?
Think about a minute.
What action do you take if an earthquake occurs now?
Let’s take a look at the video.
Hopefully, this video has helped you understand where and what to do.
First of all, please protect yourself by entering under a desk, etc. to protect yourself.
After the earthquake has healed, secure emergency exits such as opening windows and doors, and shut off gas taps if possible.
A fire can be caused by a secondary disaster.
Then go outside and move to an open place with no buildings around.
If you live near the sea, evacuate to a hill or other high ground.
Even if you survive an earthquake, you are more likely to die from the tsunami.
Many Japanese people prepare bags with emergency food, water, first aid kits, flashlights, etc. in case of such a disaster.
If something happens, the supplies may not come right away, so we have the minimum necessary items.
Thank you for reading my blog.
I hope you understand how dangerous earthquake is.
It frequently happens in Japan. So, please protect yourself and family.
