Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How much stronger is a magnitude 8.0 earthquake compared to magnitude 7.0 one on the Richter Scale?
A
7/8 as strong
B
10 times stronger
C
56 times stronger
D
twice as strong
Explanation: 

Detailed explanation-1: -The amount of energy released increases 31.7 times between whole number values.

Detailed explanation-2: -Essentially, each successive magnitude is 33 times larger than the last. That means a magnitude-8.0 earthquake is 33 times stronger than a 7.0, and a magnitude-9.0 earthquake is 1, 089 (33 x 33) times more powerful than a 7.0-the energy ramps up fast.

Detailed explanation-3: -A magnitude 7 earthquake has been described by seismologists as having “an energy equivalent to around 32 Hiroshima atomic bombs, ” as Renato Solidum, the director of the Philippine Institute of Volcanology and Seismology, told The Times in 2013.

Detailed explanation-4: -1 higher magnitude is a 10 times stronger earthquake so a magnitude 8 is 10, 000 times stronger than a magnitude 4.
