GEOLOGY

Detailed explanation-1: -Ernest Z. A 7.0 earthquake is 10 times more powerful than a 6.0 earthquake.

Detailed explanation-2: -How does magnitude relate to how much energy was produced in an earthquake? For each whole-number increase in magnitude, the seismic energy released increases by about 32 times. That means a magnitude 7 earthquake produces 32 times more energy-or is 32 times stronger-than a magnitude 6.

Detailed explanation-3: -Richter Scale However, the energy released by a seismic wave is 101.5 (or about 31.6x) the amount of its amplitude, meaning that a 7.0 quake releases 31.6 times more energy than a 6.0 quake, or 1, 000 times more energy than a 5.0 quake.

Detailed explanation-4: -Answer and Explanation: The magnitude 7 earthquake is approximately 1000 times stronger than magnitude 4 earthquake.

Detailed explanation-5: -The magnitude scale is logarithmic. That just means that if you add 1 to an earthquake’s magnitude, you multiply the shaking by 10. An earthquake of magnitude 5 shakes 10 times as violently as an earthquake of magnitude 4; a magnitude-6 quake shakes 10 times as hard as a magnitude-5 quake; and so on.
