This is a basic chart that yields the output of Earthquakes from Magnitude 1 to 10.5

You can use this and this chart to estimate the appropriate magnitude.

Notes and Sources

  • Source: Alabamaquake
  • Total Seismic Energy should only be used for real earthquakes. It shouldn't be used for physical earthquakes or earthquakes caused through abilities.
  • Shaking a minor area should not be assumed to automatically translate to an earthquake. Either a large area being shaken or evidence that we are dealing with something earthquake-like and not just some minor shaking would be needed.
  • The energy required to shake the Earth.
