What You’ll Learn

What Causes an Earthquake How scientists measure earthquakes. How earthquakes cause damage Why It’s Relevant Understanding how, where, and why earthquakes happen can help scientists and engineers reduce earthquake damage and save lives. Studying earthquakes also helps scientists understand the Earth’s interior.Earthquake Safety Information

How and Where Earthquakes Happen

Earthquakes are one of the most destructive natural disasters. A single earthquake can kill thousands of people and cause millions of dollars in damage. Earthquakes are defined as movements of the ground that are caused by a sudden release of energy when rocks along a fault move. Earthquakes usually occur when rocks under stress suddenly shift along a fault. A fault is a break in a body of rock along which one block slides relative to another.

Why Earthquakes Happen

The rocks along both sides of a fault are commonly pressed together tightly. Although the rocks may be under stress, friction prevents them from moving past each other. In this immobile state, a fault is said to be locked. Parts of a fault remain locked until the stress becomes so great that the rocks suddenly grind past each other. This slippage causes the trembling and vibrations of an earthquake.

OBJECTIVES

▸ Describe elastic rebound.

▸ Compare body waves and surface waves.

▸ Explain how the structure of Earth’s interior affects seismic waves.

▸ Explain why earthquakes generally occur at plate boundaries.
