Earthquake Rupture Area
The rupture area is the area of an earthquake rupture, which is a slip, whether on the surface or beneath, in the Earth's crust that results in a fault and displacement of some sort.
The rupture area is proportional to ten to the power of 0.91 times the seismic moment magnitude.
Formula
![QuantityVariable["RA", "Area"] == 10^(-3.49 + 0.91*QuantityVariable[Subscript["M", "w"], "Unitless"])*Quantity[1, "Kilometers"^2]](https://www.wolframcloud.com/objects/resourcesystem/marketplacestorage/resources/958/958253f3-ec12-4c0b-b79d-564aef05379b/Webpage/FormulaImage.png "Copy to Clipboard")
