To estimate the Richter magnitudedistancemaximum amplitudeUsing a Richternomogramdistance axisamplitude axis for an earthquake, one must know the (km; e.g., answer for Problem 4) of a seismograph station from the earthquake epicenter and the (mm; ~180 mm in the previous simulated seismogram below) of the S wave on that station's seismogram.
(right; essentially a graph with three axes scaled based on Richter's equations to account for distance from the earthquake epicenter), the magnitude can be estimated by drawing a line from the to the S-wave using the values for that seismograph station. Where the line crosses the magnitude axis is the Richter magnitude for the earthquake. Again, it is best to use seismograms from at least three seismographs to converge on a single best answer.
Determining Richter Magnitude - Tokyo, Japan. Using the simulated seismogram in the Problem 6 placemark from the Tokyo, Japan seismograph station, determine the maximum S-wave amplitude (mm) for the seismogram.
