An earthquake's strength is most closely related to its
select one:
a. epicenter
b. depth
c. magnitude
d. focus

The correct answer is C. Magnitude

Explanation:

An earthquake occurs as energy is released from the surface of the earth and this causes seismic waves and a shake on the ground due to phenomena such as geological faults or volcano activity. Additionally, earthquakes differ in strength or intensity, this strength is mainly related to the magnitude of the earthquake that is commonly measured according to Ritcher scale or Ritcher magnitude scale that proposes a formula based on seismic waves to classify earthquakes from 1 to 9. Therefore, an earthquake's strength is most closely related to its magnitude because this is the concept that defines the intensity of this phenomenon.
