To protect ourselves from earthquakes, it's essential to design buildings that can sustain tremors. Can anyone tell me why the design of a building is crucial in a seismic zone?
Is it because some buildings can collapse during strong earthquakes?
Exactly! To minimize risk, we should use lightweight materials and consult qualified architects. Remember, a simple 'Quake Safe' design can help protect lives.
What materials are better to use in these buildings?
Good question! In seismic areas, materials like mud or timber are preferable over heavy materials. This helps reduce the weight, making the buildings safer.
How do we fix cabinets and shelves to walls?
You can use brackets and screws. It's crucial to do this to prevent them from falling during an earthquake.
Let's summarize: Designing buildings in seismic zones requires lightweight materials and must involve professionals for safety.
What should you do if an earthquake strikes while you are at home?
Take shelter under a table!
Correct! Staying sheltered is important. Why should we stay away from tall objects?
Because they could fall on us!
Exactly! And if you are outside, what's the best action to take?
Find an open spot and drop to the ground?
Right! Keeping away from buildings helps prevent injury from falling debris. Let’s summarize: Under furniture at home, away from objects outside.
Building safety is critical, but what other preparations can we consider for an earthquake?
Do we need to have an emergency kit?
Yes! An emergency kit stocked with basics like food, water, and a flashlight is essential. What else could help?
Maybe instructions on what to do during an earthquake?
Exactly! Having a family plan ensures everyone knows how to act. Remember: preparation saves lives!
In summary: always prepare a kit, have a family plan, and educate everyone on earthquake protocols.

We know from the earlier pages that earthquakes cannot be predicted. We have also seen that they can be highly destructive. It is, therefore, important that we take necessary precautions to protect ourselves all the time. People living in seismic zones, where the earthquakes are more likely to occur, have to be specially prepared.
Earthquakes are unpredictable, which means they can happen at any time without warning. This unpredictability makes it crucial for individuals and families, especially those living in areas prone to earthquakes (known as seismic zones), to have safety measures in place. By being prepared, they can reduce the risk of injury and property damage.
Think of it like preparing for a storm. Just as you might store food and supplies in case of a hurricane, people in earthquake-prone regions should have emergency kits and plans ready at all times.
First of all, the buildings in these zones should be so designed that they can withstand major tremors. Modern building technology can make it possible.
Special building techniques are required in seismic zones to make sure structures can survive the force of an earthquake. This involves using lighter materials and simpler designs that can flex and absorb the shock rather than break apart. Architects and engineers must consider these factors when designing buildings.
Imagine a tall tree swaying in the wind. A tree that is flexible can bend without breaking, while a stiff branch might snap. Similarly, buildings designed to bend slightly during an earthquake are less likely to suffer severe damage.
In highly seismic areas, the use of mud or timber is better than using heavy construction material. Keep roofs as light as possible. In case the structure falls, the damage will not be heavy.
Choosing the right materials is crucial in earthquake-prone areas. Lighter materials like wood or specially designed mud bricks can withstand quakes better than heavy concrete or steel. In the unfortunate event that a building does collapse, lighter materials can reduce the chances of severe injury or loss of life.
Think about stacking boxes. If you stack light boxes, the total weight is less, and if they fall, they won't hurt you as much. But if you stack heavy boxes, when they fall, they can cause serious injury.
It is better if the cupboards and shelves are fixed to the walls, so that they do not fall easily. Be careful where you hang wall clocks, photo-frames, water heaters etc., so that in the event of an earthquake, they do not fall on people.
To minimize injuries during an earthquake, it is important to secure large furniture like cabinets and shelves to the walls. This prevents them from tipping over and causing harm. Additionally, placing wall hangings out of reach of where people could be injured helps maintain safety.
Picture playing a game where you have to balance objects on a table. If the table shakes, the objects might fall. By securing those objects down or placing them carefully, you can prevent a mess - or in this case, prevent injuries.
Since some buildings may catch fire due to an earthquake, it is necessary that all buildings, especially tall buildings, have fire fighting equipment in working order.
Earthquakes can cause gas lines to break and electrical wires to spark, leading to fire hazards. As a preventive measure, having accessible and functioning firefighting equipment, like extinguishers and alarms, can save lives and property during such an event.
Think of a kitchen fire while cooking. Keeping a fire extinguisher nearby ensures that if something goes wrong, you can act quickly to prevent further damage. Similarly, buildings should be equipped to handle potential fires after an earthquake.
In the event that an earthquake does strike, take the following steps to protect yourself: 1. If you are at home: Take shelter under a table and stay there till the shaking stops. Stay away from tall and heavy objects that may fall on you. If you are in bed, do not get up. Protect your head with a pillow. 2. If you are outdoors: Find a clear spot, away from buildings, trees and overhead power lines. Drop to the ground. If you are in a car or a bus, do not come out. Ask the driver to drive slowly to a clear spot. Do not come out till the tremors stop.
In case of an earthquake, immediate action is vital. Indoors, it's important to find cover under something sturdy like a table to protect yourself from falling debris. Outdoors, seeking an open area away from hazards reduces the chance of being hurt. Whether in a vehicle or on foot, remaining calm and adhering to safety procedures can make a significant difference in ensuring safety during an earthquake.
If you think about a tree swaying in a storm, the best place to be is inside where there are walls protecting you from the wind. Similarly, during an earthquake, being under a table is like having a protective barrier against falling objects.
