Question

The intensity of an earthquake is measured by?

Answer 1

Answer:

Richter magnitude scale

Answer 2

Answer:

The intensity of earthquake is measure on the richter scale.

The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included in the magnitude formula to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquakes. On the Richter Scale, magnitude is expressed in whole

numbers and decimal fractions. For example, a magnitude of 5.3 might be computed for a moderate earthquake, and a strong earthquake might be rated as magnitude 6.3. Because of the

logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured

amplitude;as an estimate of energy, each whole number step

in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value.
