The Richter scale measures earthquakes ranging from a magnitude of 1 to a magnitude of 10. 10 represents the highest level of earthquake.The effects of an earthquake range from mild to severe and include structural damage, damaged gas lines, tidal waves, fires, avalanches and flooding. The amount of damage an earthquake can cause depends greatly on the size of the 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.

During an earthquake, a rupturing fault produces several different kinds of waves that carry energy away. from the epicenter like ripples from a rock thrown into a pond. The fastest-moving seismic waves (primary or P-waves) travel about 3.7 miles per second and generally do not produce strong shaking. P-waves are followed by slower moving, …

Jan 1, 1997 · The severity of an earthquake can be expressed in terms of both intensity and magnitude. However, the two terms are quite different, and they are often confused.

Several scales have been defined, but the most commonly used are local magnitude (ML), commonly referred to as ‘ Richter magnitude ‘. 3-3.9-magnitude – Minor earthquake that may be felt. 4-4 ...It isn't that simple. There is not one magnitude above which damage will occur. It depends on other variables, such as the distance from the earthquake, what type of soil you are on, building construction, etc. That being said, damage does not usually occur until the earthquake magnitude reaches somewhere above 4 or 5.
