which statement about the mercalli scale is true? the scale has twenty ratings for an earthquakes effects. the scale rates an earthquake based on its total energy released. the scale rates an earthquake according to how much damage it causes. the scale is most useful when scientists use data from three or more seismographs.

Answer

Brief Explanations:

The Mercalli scale measures the intensity of an earthquake based on observed effects and damage at different locations, not on energy release (which is for the Richter - type magnitude scales). It has 12 ratings, not twenty. Using data from multiple seismographs is more relevant for determining magnitude on other scales.

Answer:

The scale rates an earthquake according to how much damage it causes.
