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 Richter, R = 20log(I/Io) where Io is magnitude of standard earthquake I/Io(2011) = 2.2646 I/Io(2010) = 2.7542 Intensity(2010)/Intensity(2011) = 1.216 .

1. 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.
(#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
Richter, R = 20log(I/Io) where Io is magnitude of standard earthquake
I/Io(2011) = 2.2646
I/Io(2010) = 2.7542
Intensity(2010)/Intensity(2011) = 1.216
