Locating the Epicenter of an Earthquake Practice

What type of seismic wave is the fastest and arrives first at a seismograph station?

• Surface waves

• P-waves

• S-waves

• Love waves

Which seismic wave is responsible for most of the damage during an earthquake?

• P-waves

• S-waves

• Surface waves

• Rayleigh waves

What is the primary method used to locate the epicenter of an earthquake?

• Triangulation using seismic data

• Satellite imaging

• Visual observation

How many seismograph stations are needed at minimum to accurately locate the epicenter of an earthquake using triangulation?

• One

• Two

• Three

What does a seismograph measure?

• The temperature of the Earth's core

• The speed of tectonic plate movement

• The magnitude and duration of seismic waves

• The color of the Earth's crust

What is the main difference between P-waves and S-waves?

• P-waves travel only through solids, while S-waves travel through both solids and liquids.

• P-waves are slower than S-waves.

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

• P-waves cause more damage than S-waves.

Which of the following does the Richter scale measure?

• The amount of damage caused by an earthquake

• The height of the seismic waves on the recording

• The duration of the earthquake

Look at the Earth model. Where is the focus (the starting point) of an earthquake?

What is the primary cause of tectonic plate movement?

• Magnetic fields

• Wind and ocean currents

• Gravitational pull from the moon

• Convection currents in the Earth's mantle
