Has there ever been a magnitude 13 earthquake?
The problem of a magnitude 13 is, that it is not possible according to this concept due to the earth’s physical limitations. Keep in mind, that with one magnitude higher, a quake has about 32 times more energy.
What would a 9.6 earthquake do?
This was the largest earthquake in recorded history, being larger than the 9.5 in Chile by 0.1 on the Richter scale. This caused buildings to collapse and raise parts of city up at least 30 feet, while others dropped 8 feet into the ground.

How do you calculate the Richter scale?
The Richter scale defines the magnitude of an earthquake to be R=log(IcIn) where Ic is the intensity of the earthquake and In is the intensity of a standard earthquake. Therefore, you can write the difference of two magnitudes as R2−R1=log(I2I1).
