How much bigger is a magnitude 8 earthquake compared to magnitude 7 one?
|
1 time bigger
|
|
10 times bigger
|
|
30 times bigger
|
|
100 times bigger

Explanation:
Detailed explanation-1: -On the so-called Richter scale, a magnitude 8 on a seismogram was 10 times bigger than a magnitude 7.
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: -1 higher magnitude is a 10 times stronger earthquake so a magnitude 8 is 10, 000 times stronger than a magnitude 4.
Detailed explanation-4: -Answer and Explanation: The magnitude 7 earthquake is approximately 1000 times stronger than magnitude 4 earthquake.
