What machine measures the strength of the energy waves sent out from an earthquake?

An earthquake is measured using a machine called a seismograph. The magnitude of an earthquake was measured at one time using the Richter magnitude scale., but that has been superseded by the moment magnitude scale (MMS). Subjective impressions of the intensity of an earthquake is sometimes reported using a modified Mercalli scale.

How much does the amplitude of the wave increase between an earthquake that measures 4.2 on the Richter scale and an earthquake that measures 6.2 on the Richter scale?
The energy released by an earthquake increases by 10x for every 1.0 increase in magnitude on the Richter scale. A 6.2 quake is 2.0 higher than a 4.2 quake. The increase in energy output would be calculated as such: 10x10=100. A 6.2 magnitude earthquake is 100 times more powerful than a 4.2 magnitude earthquake.
What does the Richter scale tell you about an earthquake?
The Richter scale provides a measure of the magnitude or energy released by an earthquake. It quantifies the amplitude (size) of seismic waves generated by the earthquake, which correlates with the earthquake's strength. The scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of shaking and approximately 31.6 times more energy release.
What is the difference between the Mercalli scale the Richter scale and the magnitude scale?
In seismology (the study of seismic waves or vibrations in the ground / earthquakes) the Richter scale is a magnitude scale. Magnitude scales show the amount of energy released by an earthquake. In the case of the Richter magnitude this is based on the amplitude of the seismic waves measured on a seismometer and the distance of the seismometer station from the epicentre of the earthquake. The magnitude value should be the same for a given earthquake no matter where it is recorded. The Mercalli scale is an intensity scale. This gives information on the perceived ground shaking in a specific location. The value is derived from witness reports on the perceived violence of the shaking, from the damage done to buildings and other infrastructure and also based on measurements from accelerometers and other seismic recording instruments in order to make the Mercalli intensity value a less subjective parameter. The intensity and damage to infrastructure can be influenced strongly by a number of variables including local ground conditions and the use (or otherwise) of earthquake resistant design. Please see the related questions for more information.
How is the streanth of earthquake measured?
The strength of an earthquake is measured using a seismic scale called the moment magnitude scale (Mw). It calculates the total energy released by an earthquake by measuring the amplitude of seismic waves. The scale is logarithmic, meaning that each whole number increase represents a tenfold increase in magnitude and roughly 31.6 times more energy released.
What kind of scale is used to measure the amount of seismic energy released by an earthquake?
Magnitude scales are used to assess the amoiunt of energy relaed by an earthquake. For small and medium strength earthquakes (less than magnitude 7.0) the Richter scale is used. For larger earthquakes than this, the moment magnitude scale is used.
A Richter scale measures the what of an earthquake?
The Richter Scale measures the magnitude of an earthquake which is another way of describing the energy released in the earthquake.
The Richter scale measurements what of an earthquake?
The Richter scale measures the magnitude of an earthquake which is another way of describing the energy released in the earthquake.
What is the scales use for?
The Richter scale measures how much energy is released by an earthquake.
Is The Richter system the system that measures the amount of energy released at the focus of an earthquake?
TRUE
What measures released energy of an earthquake?
The energy released by an earthquake is measured using a seismometer. The amplitude of the seismic waves recorded by a seismometer are in-turn plugged into an equation that gives a value on the magnitude scale.
The Richter scale is a system that measures the amount of energy released at the focus of an earthquake true or false?
true
Difference between intensity and magnitude?
Magnitude is a measure of the energy released by the earthquake - it is an absolute value and does not vary with where it is measured. Intensity measures the strength of the shaking at a particular location and will vary with distance, substrate conditions and other factors. It is a subjective measure which depends on observation, not measurement. The reference below sets it all out for you.Is also an answer but here's another answer:This is my answer:D(Magnitude / Intensity Comparison)(Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs while Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.)
Which earthquake scale gives the best of the energy released during an earthquake?
Invented in 1935 by Charles F. Richter, the Richter Scale measures the magnitude of earthquakes.
How is magnitude using the Richter scale?
The Richter magnitude scale (ML) scale, assigns a single number to quantify the amount of seismic energy released by an earthquake. It is a logarithmic scale based upon the horizontal amplitude of the largest displacement from zero on a seismometer. Each whole unit (i.e., 1.0) corresponds to an approximate energy increase of 32 time (e.g., a 6.0 M earthquake has 32 time the energy release of a 5.0 M).
What does the moment magnitude scale measure?
the moment magnitude scale rates an earthquake by estimating the total energy released during an earthquake
Explain the difference between magnitude and intensity of an earthquakes?
The magnitude of an earthquake is the amount of energy released at the source of the earthquake and is measured by a seismograph. Intensity is shaking strength of an earthquake at a particular location.
What is specifically does the Richter scale measure?
Richter scale measures the ground motion from an earthquakes to find the earthquakes strength. mercalli scale measures expresses intensity in roman numerals from I to XII and provides a description of the effects of each earthquake intensity.
