Seismic Waves Pg. 29 Seismology is the study of earthquakes. Seismograph- instrument that records seismic waves.

Seismic Waves 1. P waves- Fastest waves, first to be detected. Body waves-travel through the earth’s interior. 1. P waves- Fastest waves, first to be detected. Move back and forth parallel to the motion of the wave. Move through solids, liquids and gases.

2. S waves - Second fastest Move perpendicular to motion of wave. Move only through solids

Surface waves-travel along the earth’s surface. Slowest moving waves Cause the most damage during earthquakes 1.Love(L) waves move rock up and down and side to side. https://www.youtube.com/watch?v=B-8H4GmSNO8

2. Rayleigh waves - move with a rolling motion(like a typical wave) https://www.youtube.com/watch?v=5OmLkITQOlw

Shadow zone – area on Earth’s surface where no seismic waves from a particular earthquake can be detected.

Measuring Earthquakes Magnitude- strength of an earthquake. Richter scale Intensity-how much damage an earthquake causes. Mercalli scale
