【Social Studies】Protecting Our Lives from Natural Disasters: Systems That Keep Everyone Safe
Hello everyone!
Japan is known as a country prone to "natural disasters" such as earthquakes, typhoons, and heavy rain. You may have felt scared when seeing news reports about major disasters.
But don't worry! In this chapter, we will learn together about what kind of efforts people are making to protect our daily lives from disasters.
By learning about proper preparation, you can gain the power to protect yourself and your loved ones.
1. Protecting Our Lives from Earthquakes and Tsunamis
Earthquakes can happen anytime, anywhere. That’s why daily preparation is so important.
① Town Planning for Earthquakes
There are many features built into our towns to minimize damage when an earthquake occurs.
・Seismic Retrofitting: This involves reinforcing older buildings, bridges, and schools so they don’t collapse during an earthquake.
・Fire Prevention: To prevent fires after an earthquake, towns create fire-resistant roads and build houses using materials that don't catch fire easily.
・Stockpile Warehouses: Many parks and schools have "warehouses" stocked with water, food, and blankets to be used after a disaster. Try looking for one in your neighborhood!
② Escaping from Tsunamis
Near the coast, a "tsunami" may follow a large earthquake. To protect people, towns build high walls (seawalls) and maintain safe routes to "evacuation sites" located on higher ground.
【Key Concept: Jijo (Self-help), Kyojo (Mutual aid), and Kojo (Public support)】
・Jijo (Self-help): Protecting yourself on your own. (e.g., securing furniture)
・Kyojo (Mutual aid): Helping out with neighbors. (e.g., assisting elderly people during an evacuation)
・Kojo (Public support): Assistance from city halls, fire departments, and the police.
*The balance of these three is the key to building a disaster-resilient town.
Summary: Because earthquakes can happen at any time, it is important to start by preparing to protect yourself through "Jijo" (self-help).
2. Protecting Our Lives from Heavy Rain and Typhoons (Water-related Disasters)
Unlike earthquakes, we can predict when heavy rain or typhoons are coming to some extent through weather forecasts.
① Strategies for Collecting and Draining Rainwater
When it rains heavily all at once, rivers can overflow or streets can become flooded. To prevent this, there are systems like large "rainwater storage facilities" underground, which act like massive pools to temporarily hold excess water.
② Preventing Landslides
Near mountains, land is strengthened by using concrete to solidify cliffs or by planting trees to prevent them from collapsing during heavy rain.
【Fun Fact: Do you know about Hazard Maps?】
A map that shows areas that might flood during heavy rain or places where landslides are likely to occur is called a hazard map. If you look at one with your family or at school, you can see at a glance where you should go to stay safe!
Summary: Since we can know about typhoons and heavy rain in advance, it is important to check the hazard map and confirm where to evacuate early.
3. Information and Evacuation When Disaster Strikes
When a disaster occurs, how should we gather information?
① Getting Reliable Information
Use televisions, radios, emergency alerts on smartphones, and disaster prevention speakers (broadcasting through town speakers) to get the latest updates.
Common Mistake: It is very dangerous to decide on your own that "it will probably be okay!" Gathering information early can save your life.
② The Importance of Evacuation Drills
Evacuation drills held at school or in your community are practices to ensure your body moves automatically in an emergency. Actually walking the route to your evacuation site is the only way to be "truly prepared."
【Key Concept: Emergency Go-Bag】
Keep a backpack ready so you can grab it and go if you need to evacuate. Examples of what to pack:
・Drinking water and easy-to-eat food
・Flashlight
・First-aid kit (with bandages, etc.)
・Portable radio
Summary: It is important to grasp accurate information quickly and act calmly while remembering what you practiced in drills.
4. People Who Build Disaster-Resilient Towns
Many people are working to protect our town behind the scenes.
① Work of the City Hall
They make plans to open evacuation centers and distribute food when disasters occur.
② Fire Departments, Police, and Self-Defense Forces
They rescue people who are stranded and remove fallen trees or debris that block roads.
③ Volunteer Fire Corps
These are local residents who have other jobs but rush to help during fires or disasters. They are very reliable because they know the neighborhood well.
"It might feel difficult at first, but don't worry! Start by talking with your family about where the nearest evacuation site is."
Summary: Not only public support (like the city hall) but also our own efforts (self-help) and community cooperation (mutual aid) together create a town that is strong against disasters.
★ Let's review!
1. Do you remember the three concepts of cooperation: "Jijo (self-help), Kyojo (mutual aid), and Kojo (public support)"?
2. Have you checked the dangerous areas around your home using a hazard map?
3. Do you understand why evacuation drills and having an emergency go-bag ready for earthquakes and heavy rain are so important?
Just knowing these things is a huge step toward protecting yourself and the people around you. Be sure to share what you learned in social studies class with your family at home!
