Question

Quizplus · Accepted Answer

The Modified Mercalli Scale is based on human observation and perception of the effects of an earthquake on structures and people, rather than on precise measurements of the earthquake's magnitude or energy release. This scale assigns a number from I to XII to describe the earthquake's severity based on observed damage and effects on people and the environment. The other options are based on more quantitative measurements such as seismic waves, energy release, and wind speeds.
