What does it take to create a big quake?

The magnitude of an earthquake describes the amount of energy released from a given earthquake. The simulator below models how the four factors that contribute to how much energy is released from an earthquake and in turn, contribute to the magnitude. Explore these factors by creating your own earthquakes below!
