Best Answer

The Richter Magnitude Scale often shortened to Richter scale represents a number to quantify the energy released during an earthquake on a logarithmic scale.

  • Earthquakes with magnitude less than 2.0 are generally not felt by people but only registered by sensitive machines.
  • Earthquakes at the 9.0 and greater range cause severe damage or collapse to all buildings in the area.

What is the scale that rates earthquakes?

The Richter scale. For larger earthquakes (magnitude greater than 7) and for those with an epicentral distance greater than 700 km from the seismometer station, the Moment magnitude scale is used.


What scale describes an earthquake with a magnitude?

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.


What scale is measured for an earthquakes strength?

Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.


What is a measure of the strength of an earthquake?

Earthquake strength is measured using a magnitude scale. For small to moderate strength Earthquakes (< magnitude 7) the Richter scale is used. For Earthquakes between 7 and 8 the body and surface magnitude scales are used and for earthquakes larger than 8, the moment magnitude scale is used.


Is the measure of the strength of an earthquake?

Earthquake strength is measured using a magnitude scale. For small to moderate strength Earthquakes (< magnitude 7) the Richter scale is used. For Earthquakes between 7 and 8 the body and surface magnitude scales are used and for earthquakes larger than 8, the moment magnitude scale is used.


What is the difference between Richter and Moment Magnitude scale?

the moment magnitude scale is used to measure earthquake magnitude-taking into account the size of the fault rupture, the rocks stiffness,and the amount of the movement of the fault- using values that can be estimated from the size of several types of seismic waves. while a Richter scale is a numerical scale used to measure the magnitude of an earthquake, using values based on the size of the earthquakes largest seismic waves.
