Earthquake directly under the capital city
What kind of earthquake was the capital-city-type earthquake?


What is different from ordinary earthquakes with the capital-immediate earthquake?
And I will show you in detail why it is said to be dangerous.




What is the "capital-immediate earthquake"?

Yoichi
"Capital city right down type earthquake" ... It looks like a terrible scary name. But I live in Kanagawa so it's not Tokyo and it's okay.

Tama
Wait a minute! The capital-city-type earthquake does not always occur in Tokyo.

Yoichi
Because it is not the capital city. What is the capital city of Tokyo?

Tama
The "capital" here refers not only to Tokyo but to three prefectures in southern Kanto, including Kanagawa, Chiba and Saitama prefecture.

Yoichi
really? Scary. I have to know more properly.

What happens when a capital-immediate earthquake occurs?

* I do not know where in the south Kanto region the occurrence of the capital-right downtroad earthquake occurs, as was also the case with the previous conversation.
This time, it is a case where it is assumed that "Tokyo Northern Earthquake (magnitude 7.3)" with a high probability of occurrence occurred at 6 pm in winter.

Number of buildings destroyed entirely or burned down by fire About 850,000 buildings

Mudslide 900 people
Collapse such as block walls 800 people
Traffic damage 200 people

Number of injured people Approximately 210,000 people

Number of serious injuries Approximately 37,000 people

Yoichi
The number of digits, are you mistaken for mistakes? The number of damage is a bit different.

Tama
This is the terror of the capital city earthquake. But there are other possibilities that could happen.

Expected damage scenario

· Fire such as skyscrapers by long-period earthquake ground motion
· Secondary disasters are caused by the occurrence of aftershocks, etc. and raining in large quantities
· The road is blocked by the victim's cars and people, and fire engines and ambulances can not pass.
· The possibility of an accident where the trains collide with each other in the railway
· Panic centered on hoaxes such as secondary disasters caused by SNS services such as Twitter and LINE
· Public security deterioration in some shopping districts and downtown areas
· Damage to a thief aiming for a bird's nest
· Impact on the economy such as fluctuations in interest rates and stock prices

Tama
In the event of the Kumamoto earthquake, sometimes it says that the road has been blocked by too many cars, such as the media during the disaster.

Yoichi
I'm afraid I'm believing that a disaster strikes a SNS (social network) hoax. I should be careful.

Countermeasure

The capital city downhill earthquake is predicted to be many damage due to fire as can be seen from the data above.
To that end, first of all, in order to deal with proper fire when a fire happens at your home, arranging disaster prevention tools from day to day,
It is important for families to talk about disaster countermeasures properly. For example ...
· Install a fire alarm.
· Make sure that there is a fire extinguisher and make sure that fire extinguisher is properly used.
· Be sure to grasp the evacuation area in the event of a disaster.

Since the data at the time of the earthquake occurrence is forecast to the last, it may change greatly depending on the response after the earthquake occurrence.
By grasping each earthquake directly under the capital properly each one, we can reduce the scale of the damage as much as possible.

Yoichi
It is expected that there will be many fires in the capital city downhill earthquake.

Tama
But next time, it is a big earthquake of much larger scale than this.
