What was the Japan Earthquake 2011 on the moment magnitude scale?
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of the 2011 Japan earthquake on moment magnitude scale is 9.0.The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries.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.
Describe the scales that scientists use to measure the magnitude of an earthquake?
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.
What is the instrument and the scale that is used to measure the magnitude of an earthquake called?
The instrument is called "seismometer."The first sacle of measurment for earthquakes is called the richter magnitude scale after its inventor, Charles Richter (in 1935 ), which categorises them in terms obtained by calculating the logarithm of their amplitude.This scale has been replaced in the 1970s, by the moment magnitude scale which measures the size of earthquakes in terms of the energy released.The modern scale retains the familiar continuum of magnitude values defined by the older one.
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 are two advantages of the moment magnitude scale over the Richter scale?
The moment magnitude scale is more accurate for large earthquake than can cause damage.
What is the measure of an earthquakes strength called?
This is known as magnitude. It is measured on the moment magnitude scale.
What system do geologists use today for rating the magnitude of an earthquake?
Geologists use the moment magnitude scale (Mw) to rate the magnitude of an earthquake today. This scale takes into account the seismic moment, which provides a more precise measurement of an earthquake's size compared to the Richter scale.
What are the standard units used to measure the magnitude of earthquakes?
The standard units used to measure the magnitude of earthquakes are the Richter scale and the moment magnitude scale.
What scale is most often used to measure the scale of an earthquake?
The Moment Magnitude scale.
What scale is used to measure to energy of an earthquake?
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
What is an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is
What are the advantages the moment magnitude scale to measure an earthquake?
to rate an earthquake
What scales are used to measure the magnitude of earthquakes?
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.
What sort of graf can you mejer earthquakes with?
You can measure earthquakes on the Moment magnitude scale or the Richter scale

Magnitude is an earthquake's what?
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
What are the advantages of using the moment magnitude scale to measure of earthquake?
to rate an earthquake
