A numerical scale of earthquake magnitude that takes into account the size of the fault rupture is the .

A) Richter scale
B) modifies Mercalli scale
C) moment magnitude scale
D) epicentral distance scale

answer:

A. I believe

Richter scale. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.

Explanation:

The Mercalli scale bases its measurement on the observed effects of the earthquake and describes its intensity. It is a linear measurement. On the other hand, the Richter scale measures the seismic waves, or the energy released, causing the earthquake and describes the quake's magnitude. It is a logarithmic.
