Earthquakes & Seismic Waves

What are seismic waves?

• Vibrations released as an energy wave during an earthquake

• an instrument to measure how strong an earthquake is

In what order do the three types of seismic waves arrive at a seismograph?

• S-waves, Surface waves, P-waves

• P-waves, Surface waves, S-Waves

• P-waves, S-waves, Surface waves
