About how many times more intense is an earthquake that measures 8.4 on the Richter scale than an earthquake that measures 7.8 on the Richter scale?
\n" ); document.write( " Recall that Richter defined the magnitude R of an earthquake of intensity I to be
\n" ); document.write( "R = log I.
\n" ); document.write( "log I = 8.4 - 7.8
\n" ); document.write( "log I = .6
\n" ); document.write( "Antilog of .6 = 3.98 times more intense
\n" ); document.write( "-------------------------------------------------------
\n" ); document.write( "I think I did this wrong
\n" ); document.write( "Antilog(\"8.4%2F7.8\") = 11.94 time more intense!
\n" ); document.write( "
\n" );
