Detailed explanation-1: -of earthquake intensity. a: A is 10 times more intense than B. Explanation: The amount of energy released, however, increases by a factor of about 32.

Detailed explanation-2: -Earthquake A has a Richter magnitude of 7 as compared with earthquake B’s 6. The amount of ground motion is one measure of earthquake intensity. A is 10X more intense than B.

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: -In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.

Detailed explanation-5: -An earthquake of magnitude 7 is 10 x 10 = 100 times strong than an earthquake of magnitude 5. An earthquake of magnitude 8 is 10 x 10 x 10 = 1000 times stronger than an earthquake of magnitude 5. Example 1: Early in the century the earthquake in San Francisco registered 8.3 on the Richter scale.
