 Earthquake = the shaking and trembling that results from movement of rock beneath Earth’s surface  Focus = area beneath Earth’s surface where rock.

Measuring Earthquakes. Earthquakes start at the focus Earthquakes produce seismic (sizemic) waves.

Seismic Waves

Occurred along the San Andreas Fault in CA Earthquake of 1989 Occurred along the San Andreas Fault in CA Registered approximately 7.5 on the Richter Scale

Earthquake photos Look over the pictures on the following slides. Be sure to notice the amount and type of damage caused by this earthquake.

THINK, PAIR, SHARE! Using your knowledge of Plate Tectonics, how do Earthquakes cause all this damage? Give three reasons Trade with some one at your table and be ready to share!

- Earthquakes and Seismic Waves Types of Seismic Waves Seismic waves carry energy from an earthquake away from the focus, through Earth’s interior, and across the surface.

- Earthquakes and Seismic Waves Types of Seismic Waves P waves are seismic waves that compress and expand the ground like an accordion. S waves are seismic waves that vibrate from side to side as well as up and down.

Types of Seismic Waves Surface waves move more slowly than P waves and S waves, but they produce the most severe ground movements.

Is this a demonstration of p or s waves?

Identifying Main Ideas Detail Seismic waves carry the energy of an earthquake S waves vibrate from side to side as well as up and down. S-waves move at about ½ the speed of P waves! Surface waves produce the most severe ground movements & damage even though they move the slowest!. P waves compress and expand the ground. P waves move the fastest!
