Explanation:
Detailed explanation-1: -The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.
Detailed explanation-2: -The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes.
Detailed explanation-3: -A Chinese mathematician, named Zhang Heng, invented and constructed the first seismograph in A.D. 132.
