Answer 1

Answer:

The correct option is:

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

Explanation:

The Mercalli Scale was invented by Giuseppe Mercalli in 1902. It is not considered that much of a scientific method to measure to measure strength of an earthquake.

Mercalli scale uses the observation of people who experienced the earthquake, to estimate the intensity. Its measurement is based on how much effect or damage it causes to the humans, objects, buildings, and other man made things.

It is not considered a good way to measure intensity of earthquakes because some witnesses may exaggerate the effects while some may consider it nominal.
