logarithmic scale
The Decibal scale for sound measurement is an example of a logarithmic scale. The Richter scale, the pH scale, the magnitude scale for stars, the multiplicative scales on a slide rule
Using the Richter scale, a logarithmic scale.
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.
The Richter magnitude scale measures the energy released during an earthquake. That scale is a base 10 logarithmic scale with 9.9 being the highest and strongest an earthquake has been in known human history.
The strength of an earthquake is measured using a seismic scale called the moment magnitude scale (Mw). It calculates the total energy released by an earthquake by measuring the amplitude of seismic waves. The scale is logarithmic, meaning that each whole number increase represents a tenfold increase in magnitude and roughly 31.6 times more energy released.
Scientists use a machine called a seismometer to measure the strength of an earthquake. The calculated magnitude had been expressed on the Richter scale, a base 10 logarithmic scale, but with a usable limit of 6.5. Currently, magnitude is expressed on the Moment Magnitude Scale.
Richter scale measures the magnitude of earthquakes.
Rickter Scale
The Richter scale is not a linear scale. This means that an earthquake of magnitude 6 does not have twice as destructive power as the earthquake of magnitude 3. Actually, an earthquake with magnitude 5 is ten times more destructive than an earthquake of magnitude 4. The Richter scale is a logarithmic scale.
The strongest earthquake that can be measured using the Richter magnitude scale is one with a magnitude of 8.0. For earthquakes larger than this, the moment magnitude scale must be used.
The strength of earthquakes are measured by the Richter Scale. It is a base 10, logarithmic scale that measures the amplitude of the waves caused by an earthquake.
