• Valdivia, Chile

• Seismograph

• Richter Scale

What was the biggest quake of all time?

• Moment Magnitude Scale

• Valdivia, Chile

• Seismograph

• Richter Scale

This records seismic activity when the ground shakes

• Moment Magnitude Scale

• Valdivia, Chile

• Seismograph

• Richter Scale

This scale cannot be used globally or to measure quakes of the highest magnitude

• Moment Magnitude Scale

The first waves to reach the surface and have a push-pull motion (compressional)

• P-Waves

• S-Waves

• L or Surface Waves

NGSS.MS-PS4-1

NGSS.MS-PS4-2

These waves have a side-to-side motion (Shear)

• P-Waves

• S-Waves

• L or Surface Waves

Can travel through solids, liquids, and gases and are the least damaging

• P-Waves

• S-Waves

• L or Surface Waves

Travel only through solids and arrive SECOND because of a slower velocity

• P-Waves

• S-Waves

• L or Surface Waves

NGSS.HS-PS4-1

These have an up and down rolling motion and can travel along surfaces

• P-Waves

• S-Waves

• L or Surface Waves
