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

d. epicentral distance scale

Explanation:

The depth of focus from the epicenter, called as Focal Depth, is an important parameter in determining the damaging potential of an earthquake. Most of the damaging earthquakes have shallow focus with focal depths less than about 70km. Distance from epicenter to any point of interest is called epicentral distance
