Find the intensity I of an earthquake measuring R on the Richter scale (let l0 = 1). Papua New Guinea in 2011: R = 7.1.The Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.The local magnitude ML (on the Richter scale) of an earthquake of intensity I is given by ML= log(II0) where I0 is a minimum reference intensity of a “zero-level” earthquake against which the intensities of other earthquakes may be compared. How many times more intense is an earthquake of magnitude 5.8 than an earthquake of magnitude 2.9? This corresponds to a ratio of intensities of 800,000,000, so the Richter scale provides more manageable numbers to work with. Each number increase on the Richter scale indicates an intensity ten times stronger. For example, an earthquake of magnitude 6 is ten times stronger than an earthquake of magnitude 5.

The Richter scale, developed in the 1930s by Charles Richter, is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.
