Earthquakes & Seismic Waves; Monitoring (Chap. 4, Lesson 1 & 3)

earthquake

• the point on Earth's surface directly above an earthquake's focus

• the point beneath Earth's surface where rock first breaks under stress and causes an earthquake

• the shaking that results from the movement of rock beneath Earth's surface

• vibrations that travel through Earth carrying the energy released during an earthquake
