Math Challenge October 17

Scientists use something called a Richter scale to figure out how bad an earthquake really is. Earthquakes below 2 are secret earthquakes. The reason they are secret is most people cannot feel them. If the earthquake reaches 7 it is a full blown, major earthquake. What is the difference between a major earthquake and a secret earthquake?
