Understanding Earthquake Waves and Measurement

What type of wave is the first to be detected by a seismograph during an earthquake?

• S-wave

• P-wave

• Surface wave

• Love wave

Which of the following statements is true about S-waves?

• They travel faster than P-waves.

• They can travel through liquids.

• They are also known as secondary waves.

• They are the first waves to be detected.

What does a seismograph measure?

• The speed of tectonic plates

• The magnitude of an earthquake

• The intensity of an earthquake

• The motion of the ground

Which scale is used to measure the magnitude of an earthquake?

• Beaufort scale

• Richter scale

• Fujita scale

• Mercalli scale

How is the epicenter of an earthquake located?

• By using a single seismograph

• By measuring the depth of the earthquake

• By triangulating data from at least three seismograph stations

• By observing surface damage

Which of the following best describes P-waves?

• They are transverse waves.

• They can only travel through solids.

• They compress and expand the ground.

• They are slower than S-waves.

What does the Richter scale specifically measure?

• The energy released by an earthquake

• The damage caused by an earthquake

• The duration of an earthquake

• The depth of an earthquake

Which type of wave cannot travel through liquids?

• P-wave

• S-wave

• Surface wave

• Rayleigh wave

What is the primary reason for using multiple seismograph stations to locate an earthquake's epicenter?

• To measure the earthquake's depth

• To determine the earthquake's magnitude

• To calculate the time of the earthquake

• To triangulate the exact location

Which of the following waves is typically the most destructive?

• P-wave

• S-wave

• Surface wave

• Body wave
