These are known as magnitude scales. The most commonly known is the Richter magnitude scale which can be calculated from the amplitude of seismic waves measured by a seismometer. However it was not designed for use with larger earthquakes (greater than magnitude 7.0) or for ones a long way from the seismometer station (greater than around 650 km).
As such the moment magnitude scale was developed which is calculated from the cross sectional area of the slipped fault, the elastic properties of the rock mass around the fault and the size of the fault movement. This is harder to derive than the Richter magnitude but can be used for larger earthquakes.
What else can I help you with?
What is the name of the CalTech seismologist who invented the scale used to measure the magnitude of earthquakes?
The name of the CalTech seismologist who invented the scale used to measure the magnitude of earthquakes is Charles F. Richter. The scale is called the Richter scale and measures the energy released by an earthquake at its source.
What scale does PAGASA used to measure the intensity of an earthquake?
PAGASA (Philippine Atmospheric, Geophysical and Astronomical Services Administration) uses the Richter scale to measure the intensity of earthquakes. This scale is a logarithmic scale that quantifies the energy released by an earthquake.
The richter scale is used by scientists to measure the amount of energy release by an?
The richter scale is used by scientists to measure the amount of energy release by an earthquake.
What scale is used by PAGASA to measure the intensity of an earthquake?
PAGASA uses the Modified Mercalli Intensity (MMI) scale to measure the intensity of an earthquake in the Philippines. This scale assesses the effects of an earthquake on people, structures, and the environment rather than measuring the actual energy released by the earthquake.
What is another variable besides damage that scientists measure to jugde the strength of an earthquake?
Scientists also measure the magnitude of an earthquake, which represents the total energy released at the source. Magnitude is typically measured on the Richter scale or the moment magnitude scale.
What is the name of the CalTech seismologist who invented the scale used to measure the magnitude of earthquakes?
The name of the CalTech seismologist who invented the scale used to measure the magnitude of earthquakes is Charles F. Richter. The scale is called the Richter scale and measures the energy released by an earthquake at its source.
Who is famous seismologist?
One famous seismologist is Charles F. Richter, creator of the Richter magnitude scale used to measure the strength of earthquakes. Another prominent seismologist is Hiroo Kanamori, known for his research on earthquake mechanisms and his contributions to understanding earthquake processes.
Magnitude is an earthquake's what?
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
What is an intensity scale?
What something that seismologist uses to determine when an earthquake started!!
What instrument do seismologist use to study the vibrations caused by an earthquake?
mercalli scale
What does the moment magnitude scale measure?
the moment magnitude scale rates an earthquake by estimating the total energy released during an earthquake
What scale does PAGASA used to measure the intensity of an earthquake?
PAGASA (Philippine Atmospheric, Geophysical and Astronomical Services Administration) uses the Richter scale to measure the intensity of earthquakes. This scale is a logarithmic scale that quantifies the energy released by an earthquake.
What is faulding?
magnitude a measure of the energy of an earthquake specified on the richter scale.

The richter scale is used by scientists to measure the amount of energy release by an earthquake.
What is an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is
What is the scale used to measure the amount of sesmic energy released by an earthquake called?
