Earthquake Epicenter Quiz

What is an epicenter?

• The area with the least shaking during an earthquake

• The location of the earthquake's focus

• The point on Earth's surface directly above where an earthquake begins

• The point underground where an earthquake starts

What are P-waves?

• Waves that cannot be recorded

• Waves that cause the most damage

• The fastest seismic waves

• Waves that arrive last during an earthquake

What is the role of recording stations?

• To create maps of earthquake zones

• To predict future earthquakes

• To provide entertainment during earthquakes

• To monitor seismic activity 24/7

What does the distance formula D = (Tp - Ts) * V calculate?

• The amplitude of seismic waves

• The speed of seismic waves

• The distance to the epicenter

• The time taken for seismic waves to travel

How many recording stations are needed for accurate triangulation?

• Four

• Three

• Two

• One

What is a seismograph?

• A device that predicts earthquakes

• An instrument that records seismic waves

• A map showing earthquake zones

• A type of seismic wave

What is the focus (hypocenter) of an earthquake?

• The location of the recording station

• The area with the strongest shaking

• The point where the earthquake originates underground

• The point on the surface where the earthquake is felt

What is the purpose of triangulation in locating an epicenter?

• To find the depth of the earthquake

• To determine the exact location of the epicenter

• To measure the intensity of shaking

• To predict future earthquakes

What is a seismogram?
