carl1 Posted November 21, 2008 Share Posted November 21, 2008 -------------------------------------------------------------------------------- Hi all, a richter scale is based on powers of ten, which means that an increase of one unit on the scale implies a tenfold increase in ground motion. ie: a mag 2 earthquake produces 10 times more maximum ground motion than a mag 1 quake. A mag 3 quake produces 10 times more again, which is 10 x 10 =100 times greater ground motion than a mag 1 quake. so my question is:How many times greater ground motion of a mag 7 compared to a mag 5. Would i be in thinking the anwser would be 200 or would it just be a 2. (ie: the difference being a mag 2) thanks carl1 Link to comment Share on other sites More sharing options...
swansont Posted November 21, 2008 Share Posted November 21, 2008 How many times greater motion is there in a mag 7 vs a mag 6? How many times greater motion is there in a mag 6 vs a mag 5? Hint: you've already done the analysis in your first paragraph. Link to comment Share on other sites More sharing options...
