The rock that shifted to cause earthquake B released more energy.

The magnitude of earthquake measures the intensity or size of the earthquake.

The magnitude of the earthquake can be determined using Richter scale as follows;

[tex]R = log(\frac{I_c}{I_n} )[/tex]

where;

  • [tex]I_c[/tex] is the intensity of the earthquake
  • [tex]I_n[/tex] the intensity of a standard earthquake

[tex]I = PA = \frac{E}{t} \times A[/tex]

where;

  • I is intensity
  • P is power
  • E is energy
  • A is area

Intensity of earthquake is directly proportional to the energy of the earthquake.

The magnitude of the Earthquake B is greater than Earthquake A.

Thus, we can conclude that the rock that shifted to cause earthquake B released more energy.
