From this figure I know that the earthquake is located at the point where all three circles are intersecting. It looks as if it is on the boarder of Montana and Colorado. 9.10. Using the nomogram, determine the Richter magnitude for the three earthquakes listed (see p. 169 in Geoscience Laboratory). S arrival minus P arrival Amplitude Magnitude (A) 8 seconds 20 millimeters 4 (B) 8 seconds 0.2 millimeters 2 (C) 6 seconds 10 millimeters 3.5 9.14.

Where is the location of that June 19 quake (to the nearest tenth of a degree latitude and longitude)? Follow the steps 1 through 4 to complete the table below (refer to and complete Appendix D, reproduced from Geoscience
