A magnitude scale is simply a metric for quantifying the energy released in an earthquake and the amplitude of the waves the earthquake emits.
The most well-known magnitude scale in America is the Richter scale, which is equated in base 10 (that is, an earthquake that scores 5.0 on the Richter scale will have an Amplitude ten times greater than that of an earthquake that scores a 4.0 on the Richter scale).
The magnitude of the 2010 Haiti earthquake on the Richter scale was 7.0
This is known as magnitude. It is measured on the moment magnitude scale.
The magnitude of the 2011 earthquake in Christchurch, New Zealand, was 6.3 on the Richter scale.
The most commonly used scale to measure the magnitude of earthquakes is the Richter scale. However, the moment magnitude scale (Mw) is now more widely used as it provides a more accurate measurement for larger earthquakes. Other scales include the Modified Mercalli Intensity (MMI) scale, which measures the intensity of shaking at a specific location.
The most commonly used scale to express the magnitude of an earthquake is the Richter scale. This scale measures the amplitude of seismic waves produced by an earthquake. Another widely used scale is the moment magnitude scale, which provides a more accurate measurement for larger earthquakes.
There are a number of earthquake magnitude scales, including the moment magnitude scale (the scale currently favoured by seismologists), the Richter or local magnitude scale and the surface wave magnitude scale.
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
The scale currently used to express the magnitude of earthquakes is the Richter scale or the moment magnitude scale (Mw). The moment magnitude scale is more commonly used today as it provides a more accurate measurement of an earthquake's size compared to the Richter scale.
The magnitude of the 2010 Haiti earthquake on the Richter scale was 7.0
This is known as magnitude. It is measured on the moment magnitude scale.
Magnitude
An earthquake's magnitude is expressed as a number on the Richter Scale.
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
The magnitude of the 2011 earthquake in Christchurch, New Zealand, was 6.3 on the Richter scale.
The Richter scale is a magnitude scale - it measures the amount of energy released by an earthquake. As such tit is a way of quantifying earthquake magnitude and comparing it to other earthquakes.
Magnitude of the 2011 Japan earthquake on moment magnitude scale is 9.0.The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries. The United States Geological Survey (USGS), for example, uses the moment magnitude scale designated as MMS or Mw to measure all large earthquakes.UPDATE: Official magnitude was updated to 9.1 on Nov 7, 2016.
