Earthquake Waves and Earthquake-Resistant Design

Front

What are Primary waves (P-waves)?

Back

Primary waves (P-waves) are seismic waves that can travel through solids, liquids, and gases. They are the fastest seismic waves and arrive first during an earthquake.

Front

What are Secondary waves (S-waves)?

Back

Secondary waves (S-waves) are seismic waves that can only travel through solids. They are slower than P-waves and arrive after them during an earthquake.

Front

What is the best foundation type for earthquake resistance?

Back

A foundation with springs is the best for earthquake resistance as it can absorb and dissipate seismic energy.

Front

What is density?

Back

Density is the mass of an object divided by its volume. It determines how heavy an object is for a given size.

Front

Which has higher density: a dump truck full of feathers or a dump truck full of bricks?

Back

A dump truck full of bricks has higher density than a dump truck full of feathers.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, generated by earthquakes or other geological activity.

Front

What causes earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust, often due to tectonic plate movements.

Front

What is a seismogram?

Back

A seismogram is a record produced by a seismograph that shows the motion of the ground during an earthquake.

Front

What is the difference between P-waves and S-waves in terms of travel medium?

Back

P-waves can travel through solids, liquids, and gases, while S-waves can only travel through solids.

Front

How do buildings designed for earthquakes differ from regular buildings?

Back

Earthquake-resistant buildings are designed with flexible materials and special foundations to absorb seismic energy and reduce damage.
