Answer:
Intensity depends on the distance form the ground and source of energy.
Explanation:
- Earth quake that has an intensity of 1.5 on the Richter scale can be detected only through the seismograph. The earthquake with an intensity of 0 levels on the Richter scale that is below micro will not be felt or rarely felt in scale.
- This can be defied by the Richter scale formula of R=log(IcIn), Ic is the intensity and In is the intensity if the standards earthquake. Hence the difference will be R2−R1=log(I2I1)
