Which are true of "Richter" or "Local" magnitude calculations?
A) Use maximum S-wave amplitude on a seismogram
B) Use a nomograph to relate distance, magnitude, and amplitude
C) Most commonly used
D) All of these are true
Richter Magnitude
A scale historically used to quantify the size of earthquakes based on the amplitude of seismic waves, replaced by the more accurate moment magnitude scale for large events.
Nomograph
A type of graph used in seismology to determine the local magnitude of an earthquake.
S-Wave Amplitude
The measure of the height of the secondary or shear waves, which are one type of seismic wave produced by earthquakes.

Final Answer :
D
Explanation :
The Richter or Local magnitude scale uses the maximum S-wave amplitude on a seismogram, employs a nomograph to relate distance, magnitude, and amplitude, and is the most commonly used scale for measuring the size of earthquakes.
