What is the difference between earthquake magnitude and intensity?
What is the difference between earthquake magnitude and intensity?
- Magnitude is a measure of how an earthquake feels to humans, while intensity describes the size of the seismic waves.
- Magnitude is a qualitative measure of the effects of an earthquake, while intensity is a quantitative measure of the size of an earthquake.
- Magnitude is a quantitative measure of the size of an earthquake, while intensity is a qualitative measure of the effects at a particular location. (correct)
- Magnitude is based on observed ground motion characteristics, while intensity reflects the destruction caused by the earthquake.
