Quizplus · Accepted Answer

The intensity of an earthquake is measured on the Richter scale, which is a logarithmic scale. The formula for the Richter scale is M = log (A/Ao), where M is the magnitude of the earthquake, A is the amplitude of the seismic waves, and Ao is the amplitude of the smallest seismic waves that can be detected. In this problem, the magnitude of the earthquake is 5.9, so we can plug this value into the formula to find the intensity of the earthquake:M = log (A/Ao)5.9 = log (A/Ao)10^5.9 = A/AoA/Ao = 794,328Therefore, the intensity of the earthquake is 794,328.
