Whenever there is an earthquake you will always find a volcano nearby.

Some earthquakes are caused by what humans do.

Earthquakes happen every day.

Earthquakes are spread out fairly evenly across the world.

Earthquakes generally happen along tectonic boundaries.

In an earthquake, it is usually safer to be in a town rather than the countryside.

When engineers design buildings to withstand earthquakes, they need to consider how big the loads will be on the buildings.

In an earthquake area, the way a building is constructed is more important than its age or weight.

Heaviest buildings are always the most stable.

What is an earthquake?

When engineers plan their designs for any building they have to be sure that it won’t fall down. Look at the diagram below. From your experiences in the classroom when you built structures to support sandbags, which shape do you think engineers would find helps to give the most strength and stability to their designs for buildings?

Engineers also have to consider the effects of different types of loads (forces) on the building. Which of these four loads does not change from day to day?

A student is shaking a rope to demonstrate wave patterns. He makes the following four patterns: Which pattern shows the smallest transfer of energy?

Which pattern would you expect to see on a seismograph indicating the earthquake of greatest severity?

Two students are testing out a seismometer app on their phone using a shaking table. They put the phone on the table and shake it backwards and forwards to create patterns on the phone screen. Which of the following patterns might they see?

A student makes a wave pattern on the floor with a rope. She moves her arm from side to side the same distance while holding the rope. She creates a pattern with the rope like the one shown on the right. What should she do to reduce the amplitude of the waves?

You live in a suburb of San Francisco with your family. One night, you are suddenly woken by voices shouting and a deep rumbling sound. You get out of bed wondering if you have had a bad dream. It is pitch black outside, and there are no street lights on. The rumbling is getting louder and the floor begins to move under your feet. You realize that an earthquake is happening. What should you do?

Which of the following forces are important to consider when developing a building able to withstand a severe earthquake? Put a check mark next to each force type to show if it is Important or Not Important. Torsion

Which of the following forces are important to consider when developing a building able to withstand a severe earthquake? Put a check mark next to each force type to show if it is Important or Not Important. Magnetic

Which of the following forces are important to consider when developing a building able to withstand a severe earthquake? Put a check mark next to each force type to show if it is Important or Not Important. Compression

Which of the following forces are important to consider when developing a building able to withstand a severe earthquake? Put a check mark next to each force type to show if it is Important or Not Important. Tension

Which of the following forces are important to consider when developing a building able to withstand a severe earthquake? Put a check mark next to each force type to show if it is Important or Not Important. Bending

You will have read about Shoichi Sakamoto, a Japanese inventor, who designed a very different house capable of withstanding damage due to an earthquake. His idea was to lift the house off its foundations the moment an earthquake struck so that it floated on a cushion of air 3 cm thick. He demonstrated this using a model. The diagram below shows how the house would be levitated. Experts in safety of buildings during earthquakes considered the idea but found some problems and several reasons why levitating a house during an earthquake would not work. Do you levitation would work to protect a building during an earthquake? Here are five reasons why it might not work. Put a check mark next to each statement to show if you Agree or Disagree. Lifting a house 3 cm above the foundations would only protect a house if the seismic waves were less than 3 cm in amplitude.

The house might be empty so no one could push the button to make the compressor work.
