There are many different ways to measure different aspects of an earthquake: Magnitude is the most common measure of an earthquake's size. It is a measure of the size of the earthquake source and is the same number no matter where you are or what the shaking feels like.Now, 40 years later, more than 1,100 earthquakes have been recorded under the east side of the caldera in the past month, including a 4.0 magnitude quake on 2 October and a 4.2 on 27 September.The Richter scale is logarithmic, with each step up the scale marking a tenfold increase in quake strength—a 4.0 quake on the Richter scale, for instance, releases 10 times the energy of a 3.0 earthquake. The problem was that for large quakes—over 7.0 on the scale—the Richter scale was less reliable. Earthquakes are a natural phenomenon that occurs when there is a sudden release of energy in the Earth’s crust, resulting in the shaking or trembling of the ground. These events are caused by the movement of the Earth’s tectonic plates and are a common geological occurrence. Read here to learn more.

Earthquakes, large and small, happen every single day along zones that wrap around the world like seams on a baseball. Most don't bother anybody, so they don't make the news. But every now and ...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. Another measure of the relative strength of an earthquake is the size of the area over which the shaking is noticed. This measure has been particularly useful in estimating the relative severity of historic shocks that were not recorded by seismographs or did not occur in populated areas.Earthquake detection A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram.

By Earthquake Hazards Program. Throw a rock into a pond or lake and watch the waves rippling out in all directions from the point of impact. Just as this impact sets waves in motion on a quiet pond, so an earthquake generates seismic waves that radiate out through the Earth. An earthquake's seismic moment can be estimated in various ways, which are the bases of the M wb, M wr, M wc, M ww, M wp, M i, and M wpd scales, all subtypes of the generic M w scale. See Moment magnitude scale § Subtypes for details. Seismic moment is considered the most objective measure of an earthquake's "size" in regard of total energy.On average, a major earthquake—one with a magnitude of 7.0-7.9—strikes somewhere on the planet more than once a month. A great earthquake—with a magnitude of 8.0 or higher—occurs about once a year. An earthquake can happen anywhere. However, the vast majority of earthquakes occur at the boundaries between tectonic plates. Continental ...There are many different ways to measure different aspects of an earthquake: Magnitude is the most common measure of an earthquake's size. It is a measure of the size of the earthquake source and is the same number no matter where you are or what the shaking feels like. Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. Intensity scales date from the late 19th and ... Today, an earthquake's size is typically reported simply by its magnitude, which is a measure of the size of the earthquake's source, where the ground began shaking.
