\n" ); document.write( "If an earthquake in 1906 had an intensity of 8.27 on the Richter Scale & a 2nd quake in 1989 had a magnitude of 6.9, How many times greater was the magnitude of the 1906 quake than the 1989 quake?\r
\n" ); document.write( "\n" ); document.write( "I got 1.37 & I understand the intensity that if one quake is 7 & the other is 6 on the R.S. than the one that is 7 is 10 times as intenseas the one that is 6. So this one mentioned above is 10 times plus the .37 right? What is the correct answer? 10.37? \n" ); document.write( "

To compare the differences in magnitudes of earthquakes using the Richter scale, use the following:
\n" ); document.write( "Subtract the smaller Richter reading from the larger and use this as the exponent for 10.\r
\n" ); document.write( "\n" ); document.write( "To compare the two Richter readings in your problem, 8.27 - 6.9 = 1.37 Now use this as the exponent for 10.
\n" ); document.write( " $\"10%5E1.37+=+23.44\"$ \r
\n" ); document.write( "\n" ); document.write( "The magnitude of the 1906 earthquake was 23.44 times larger than the 1989 earthquake.\r
\n" ); document.write( "\n" ); document.write( "P.S. The intensity of an earthquake diminishes as the distance from the epicenter. \n" ); document.write( "
