 ```the richter scale is logarithmic, meaning that each increase of 1 on the richter scale corresponds to an increase of 10 in the amplitude of the seismic waves created by an earthquake. An earthquake that measures 8 on the Richter scale has how many times more ground-shaking than a quake that measures 6 on the richter scale?```
 ```Howdy daisy001-ga, The Argonne National Laboratory Division of Educational Programs, hosts "NEWTON," which is an "electronic community for Science, Math, and Computer Science K-12 Educators." They have a brief, but nice, explanation of the Richter scale. http://www.newton.dep.anl.gov/askasci/gen99/gen99039.htm "For example, a magnitude 6 earthquake will produce ten times the ground motion that a magntidue 5 earthquake will produce, but ten times less ground motion than a magnitude 7 earthquake. The amount of energy released by an earthquake varies by a factor of 30 for each unit increase in the magnitude--a magnitude 6 earthquake produces 30 times the energy of a magnitude 5 earthquake and 30 times less energy than a magnitude 7 earthquake. Incidentally, a magnitude 5 earthquake produces about as much energy as the nuclear bombs dropped on Japan during World War II." In your example, a magnitude 8 earthquake would produce 100 times (10 times 10) the ground motion of a magnitude 6 earthquake and 900 times (30 times 30) the amount of energy would be released by the magnitude 8 earthquake than a magnitude 6 earthquake.
