Tsunami via Earthquake calcs[]
A more obscure type of AP feat in fiction is Tsunami via Earthquake feat. These involve Tsunamis that were created by underwater Earthquakes that characters might have created by for example causing an explosion, punching the ground, lifting the ground via sheer lifting strength, etc. Some of the fundamentals to tsunamis is that they can be created by one of 4 methods:
- Upthrust of the sea floor (Caused by an underwater earthquake)
- An underwater volcanic eruption
- Landslide
- Meteor Crash
For this type of method to be truly applicable to the feat at hand, there must be contextual evidence of the first method and none of the other ones.
Once this contextual evidence is proven to a satisfactory extent, the procedure may be started.
- Step 1: Find the height of the desired tsunami caused by an earthquake by any means, whether it being given by the manga itself or via pixel scaling and angular sizing.
- Step 2: Once the height of the tsunami has been determined, use this formula that came from this article. 'H' is for the Tsunami height you determined during Step 1, and using this formula will give you the Moment Magnitude required for the corresponding tsunami.
Mw1=1.5667∗Log(H)+7.0781 <-------- This is the formula to convert Tsunami Height into a Moment Magnitude
- Step 3: You now have your Moment Magnitude. Because our equations for Earthquake Magnitude to Energy conversion is in the Richter scale, and not the Moment Scale, we must convert the magnitude into a Richter Magnitude. This can be done with the following equation put together from these two articles .
Me = Mw + (-4.9 + 4.7)/1.5 <-------- This is the formula to convert the Moment Magnitude into a Richter Magnitude.
- Step 4: Once you have converted the magnitudes, we can now use the converted Richter Magnitude to compute the Radiated Energy. We input the computed magnitude into this Earthquake Calculator to get our final tally in both Joules and Tons of TNT.
