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of the 2011 Japan earthquake on moment magnitude scale is 9.0.The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries.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 system do geologists use today for rating the magnitude of an earthquake?
They use the Richter scale to measure magnitude and Moment Measure to measure energy released.
What scales are used to measure the magnitude of earthquakes?
The instrument that is used to measure the magnitude of an earthquake is a seismometer.
What scale is most often used to measure the scale of an earthquake?
The Moment Magnitude scale.
What scale is used to measure the 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 Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.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 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 are 3 ways to measure an earthquake?
the Richter scale, Mercalli scale, and 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 sort of graf can you mejer earthquakes with?
You can measure earthquakes on the Moment magnitude scale or the Richter scale
Is a saffir-simpson scale used to measure the strength and the magnitude of an earthquke?
No. The Saffir-Simpson scale is used to rate hurricane strength. Earthquakes are measure on the Moment Magnitude scale (formerly the Richter scale).

What is the measure of an earthquakes strength called?
This is known as magnitude. It is measured on the moment magnitude scale.
