## Which scale measures the amount of damage after an earthquake

Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 12.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.Focus and Epicenter. The focus, also called a hypocenter of an earthquake, is the point of initial breaking or rupturing where the displacement of rocks occurs. The focus is always at some depth below …

_{Did you know?However, not all of the energy released in an earthquake will necessarily be felt at the surface, depending on the earthquake's depth. In New Zealand, where earthquakes occur from near the surface right down to a depth of over 600 km, the Modified Mercalli intensity scale is a better indicator of an earthquake's effects on people and their environment.The moment magnitude scale is broadly similar to the Richter scale, but it takes more factors into account, including the total area of the fault that moves during the earthquake, and how much it moves. This produces a magnitude number that is a better indicator of the total amount of energy released by the earthquake.The overall damage is estimated to be at about $10 billion.
