Respuesta :
The Mercalli Scale rates an earthquake according to how much damage it causes
The Mercalli Scale uses Roman numerals to rank the damage caused by an earthquake
Explanation:
The Mercalli Scale measures the intensity, extent, or amount of damage or caused due to an earthquake in an area.
The damages caused by an earthquake on humans and other living organisms, buildings, objects, bridges, landforms, and other structures on the earth's surface are observed and recorded through the Mercalli Scale.
The intensity of the damage caused depends upon the earthquake's severity and the location and at the epicenter, the intensity would be high.
The Mercalli Scale is calibrated as a linear scale using Roman numerals ranging from I to XII, with XII being highest depicting the extreme damage or devastation caused in an area by an earthquake .
Answer:
Option B - This scale rates an earthquake according to how much damage it causes.
Option D - This scale uses Roman numerals to rank the damage caused by an earthquake.
Explanation:
The intensity of an earthquake gives an understanding of the severity of the earthquake. Therefore, it would be better to measure an earthquake on the basis of destruction caused by it.
Hence, with this concept Harry Wood and Frank Neumann developed Modified Mercalli intensity scale in 1931 which ranks an earthquake based on its after effects from “not felt” to “catastrophic” destruction. The ranks are depicted through Roman numerals
Hence, option B and D are correct
