Question 11: (1 points)
(#50 from textbook)
The January 2, 2011 earthquake in Chile registered a magnitude of 7.1,whereas the one that struck Chile on February 27, 2010 was an 8.8 magnitude earthquake. Compare the intensity of the 2010 earthquake with the one in 2011.
Solution
A magnitude 8.8 earthquake is 50 times BIGGER on a seismogram than a magnitude 7.1 earthquake. The magnitude scale is logarithmic, so
