The Richter scale (or local magnitude scale) indicate the energy released by a particular earthquake.
The numerical value is obtained from the logarithm of the maximum amplitude of seismic waves as recorded on a seismometer. This value is then scaled to account for the distance from the epicentre of the earthquake to the seismometer so as to allow the value to be correlated with the local magnitude readings from other seismometers in differing locations (as seismic waves lose their energy as they propagate through the earth so if this correction was not made, then different seismometer stations at different distances would give differing Richter magnitudes for the same earthquake).
It uses a logarithmic mathematical formula which is calibrated so that a ten fold increase in amplitude relates to a single whole number increase on the scale (e.g. an earthquake with a Richter magnitude of 5 has seismic waves with a maximum amplitude 10 times larger than those for a magnitude 4).
The equation for calculating the Richter magnitude (MR) is shown below:
MR = (Log10A) - (Log10A0)
Where
A = maximum zero to peak amplitude of seismic wave (mm) recorded.
A0 = Empirical function derived from the distance from seismometer station to earthquake epicentre
Log10A0 From 0 to 200 km distance:
Log10A0 = 0.15 - 1.6 log(distance in km)
Between 200 and 600 km distance by:
Log10A0 = 3.38 - 3.0 log(distance in km)
it works on the principle of gallileo pendulum theory. it moves according to the vibration of earth quake. the ink pen is suspended in bottom of pendulum bob.
so that it records the intensity of earth quake.
firstly take a piece of paper ,a thick wire,small marker.Then, fold the wire on one side
By measuring the vibrations from the earths crust and core, It sketches in the vibrations based of richter detecters around an area
Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.
The Richter scale uses Arabic numerals.
Richter scale measures the magnitude of earthquakes.
Yes it does. The Richter Scale measures intensity for earthquakes!!
Charles Richter was a physicist who created the Richter scale. This scale allowed scientist to quantify the size of an earthquake.
Richter scale is used for measuring earthquakes. It is a scale which works from 1 to 10 magnitude.
The Richter scale
My rebuilt engine is about 7.5 on the Richter scale! Yesterday's earthquake read 3.2 on the Richter scale. The Richter scale was developed in the 1930s.

The Richter scale uses Arabic numerals.
That is impossible as the Richter scale is for measuring earthquakes.
It reached 7.0 on the richter scale
4-5 on the Richter scale.
No. The Richter Scale rates the intensity of earthquakes. There is not intensity scale for tsunamis.
The scale of Richter scale is 10. It calculates the earthquake on a scale of 10.
