Earthquake P and S Waves

We use this tool to measure seismic waves during earthquakes

• Seismographs
• magnitude
• actual magnitude
• sonograph

These are the first waves released during an earthquake

• S waves
• Surface Waves
• P waves

These are the secondary, or second waves to be released. They cannot travel through the liquid outer core

• S waves
• Surface Waves
• P waves

This is the area beneath the Earth's surface where the earthquake begins

• epicenter
• focus
• fault line
• tectonic plate

This is the area above ground where the earthquake starts

• focus
• epicenter
• p waves
• plate boundary

P Waves travel through...

• Solids
• Liquids
• Both

S Waves travel through...

• Soilds
• Liquids
• Both

Energy from an Earthquake travels as.....

• seismic waves
• intergalactic waves
• sound waves
• plasma waves

Which type of wave arrives to a point first?

• Primary Waves (P-Waves)
• Secondary Waves (S-Waves)
• Rayleigh Waves
• Love Waves

Which body wave is pictured?
