1. Determining Richter Magnitude - Busan, South Korea. Using the simulated seismogram in the placemark from the Busan, South Korea seismograph station, determine the maximum S-wave amplitude (mm) for the seismogram.
a. -65 mm
b. -90 mm
c. -56 mm
d. 18 mm 4.
2. Determining Richter Magnitude - Tokyo. Akita, and Busan, SE Asia. Using the Problem 9 - Richter nomogram overlay (not the one in the overlay balloon) and the Line tab of the Ruler tool, draw a line for each seismograph station using the distance from each seismograph to the earthquake epicenter (from Problem 4 in km; left axis) and the S-wave amplitude measured from its Seismogram (in millimeters: right axis). Save each line after drawing them. Estimate the Richter magnitude based on where the lines for the three seismographs cross the center axis of the Hichter nomogram (they may not intersect perfect. What is the Richter magnitude for this earthquake?
a. -5.8-6.0
b. -6.1-6.3
c.-4.5-4.7
d. -6.7-6.9
