Answer:
The correct answer is: a) it relies on testimony from people.
Explanation:
The Mercalli intensity scale, unlike the Richter scale, does not directly measure the energy of an earthquake. Rather, it takes into account the damage and effects that the earthquake caused. When there is little damage, it relies on the testimony of people who felt the earthquake, which may vary and is ultimately subjective to people's perception.
The Mercalli Intensity Scale ranges from "Not felt" to "Catastrophic" going through 12 scale intensities.
One important influence is climate ie many Canadians, especially from the cold Prairies like to move to Vancouver, BC because the climate is so much milder in the winter due to the proximity of the Pacific Ocean. Another important influence is topography, so that if a country is mostly mountainous, the cost of road building will be more expensive than on, say the prairies or on the coastal desert of Peru and northern Chile. Another important influence of geography is the presence of fertile soil such as in El Salvador from the ash of the volcanoes to grow coffee in, or the fertile floodplain of the Nile River in Egypt.
Answer:
