Earthquake Waves and Earthquake-Resistant Design

Front

What is the definition of VOLUME?

Back

The amount of space something takes up.

Front

What are P-waves?

Back

Primary waves that are the first to arrive during an earthquake, traveling through solids and liquids.

Front

What are S-waves?

Back

Secondary waves that arrive after P-waves, traveling only through solids.

Front

What is a seismogram?

Back

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

Front

What is the purpose of earthquake-resistant design?

Back

To construct buildings that can withstand the forces of an earthquake.

Front

What type of foundation is best for earthquake resistance?

Back

Springs, as they can absorb shock and allow movement.

Front

What is liquefaction?

Back

A phenomenon where saturated soil loses strength and behaves like a liquid during an earthquake.

Front

What is the difference between magnitude and intensity of an earthquake?

Back

Magnitude measures the energy released at the source, while intensity measures the effects of the earthquake at different locations.

Front

What is a fault line?

Back

A fracture in the Earth's crust where blocks of land have moved past each other.

Front

What is the Richter scale?

Back

A scale used to measure the magnitude of earthquakes.
