Earthquakes are natural vibrations of the ground Most quakes are caused by movement along enormous frac- tures in Earth's crust In this activity,
When that energy was released as an earthquake, more than 75,000 people were killed and 3 million were made homeless Section 19 1 528 Chapter 19 •
At these breaks rocks can move releasing the energy built up as a result of stress • Earthquakes are the result of this movement and release of energy
Stress and Strain 1 When do most earthquakes occur? • when rocks fracture (break) deep within Earth 2 When do fractures form? • when stress exceeds the
