The Richter scale is a logarithmic scale.
\n" ); document.write( "You subtract the two values.
\n" ); document.write( "The value is then raised to the power of ten.
\n" ); document.write( " $\"x=8.2-6.2=2.0\"$
\n" ); document.write( " $\"D=10%5Ex\"$
\n" ); document.write( " $\"D=10%5E%282.0%29\"$
\n" ); document.write( " $\"D=100\"$
\n" ); document.write( "A magnitude 8.2 earthquake is 100 times stronger than a magnitude 6.2 earthquake. \n" ); document.write( "
