Question

Which statement describes the Mercalli scale? This scale measures seismic waves based on their size. This scale rates an earthquake according to how much damage it causes. This scale produces a single rating for earthquakes that reach the surface. This scale measures the magnitude of an earthquake based on the size of seismic waves.

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.

Answer 2

Mercalli scale rates an earthquake according to how much damage it caused.

Mercalli scale makes use of observable data gained through affected areas in order to determine the level of damage that the earthquake has caused, which is generally subjective in nature.

The scale generally measures earthquake intensity by making use of data such as the impact on Earth, environment, and humans. Thus, it helps in estimating whether the earthquake was deadly or not.
