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:A is 10 times more intense than B
b:A is 1000 times more intense than B
c:Richter magnitude doesn't measure intensity
d:B is 0.001 times as intense than A
Answers
Answer:
A is 10 times more powerful than earthquake B
Answer:
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: A is 10 times more intense than B.
Explanation:
The amount of energy released, however, increases by a factor of about 32. Looking at the same magnitudes, a magnitude 6.0 earthquake releases 32 times more energy than a magnitude 5.0; 7.0 releases about 1,000 times more energy, and a magnitude 8.0 releases about 32,000 times more energy than a 5.0.
The Richter Scale (more accurately referred to now as the “local magnitude” scale or ML), like all other magnitude scales to follow, is logarithmic, meaning each unit up on the scale equals a 10-fold increase in amplitude–e.g. a 7.0 earthquake is 10 times stronger than a 6.0 earthquake, and 100 times stronger.
