Two of the most common methods used to measure earthquakes are the Richter scale and the moment magnitude scale. The Mercalli scale also measures the effects of an earthquake at different locations.A magnitude-5.9 earthquake, which was felt across five Australian states and territories, was caused by a previously unknown fault line deep within the Earth's crust, according to new research.Seismic magnitude is not a measure of the physical size of the earthquake fault (as might be quantified by its area or its slip) but rather of the amount of vibration that it emits. The appeal of the Richter magnitude scale is twofold. First, an earthquake is summarized by an easy-to-remember and easy-to-interpret single-digit number. An earthquake’s strength can be measured in a variety of ways; the two most common methods are intensity and magnitude. Earthquake intensity is a measurement of the surface damage resulting from an earthquake. It is most commonly measured with the Mercalli scale as seen in Figure 10.

Measurement of the severity of an earthquake can be expressed in several ways, but the two most common scales used by seismologists are intensity and magnitude. Earthquake intensity. Intensity is a qualitative measure of the strength of shaking caused by an earthquake determined from the observed effects on people, objects and buildings. A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor.
