There are 12 intensity levels in a Meracalli Scale.
I - Weak - Felt only by a few people at best, especially on the upper floors of buildings
II
III
IV
V
VI
VII - Strong - Difficult to stand; furniture broken, and can be noticed by people in vehicles
VIII
IX
X
XI
XII - Total destruction - buildings leveled, ground moves in waves, and the landscape altered
The Modified Mercalli Intensity scale is used to measure the intensity of an earthquake based on its observed effects on people, buildings, and the natural environment rather than the seismic energy. It provides a qualitative assessment of the shaking and damage caused by an earthquake at a specific location.
The damage done by an earthquake is typically measured using the Richter scale, moment magnitude scale, or the Modified Mercalli Intensity scale. These scales take into account factors such as the energy released, amount of ground shaking, and the impact on structures and people.
The factors that determine an earthquake's intensity on the Modified Mercalli Intensity Scale include the earthquake's magnitude, distance from the epicenter, local geology and ground conditions, and building structures. Intensity also depends on the impact of ground shaking, surface faulting, landslides, and other secondary effects.
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.
According to the US Geological survey, the maximum intensity of the magnitude 9.5 Chilean earthquake of 1960 was rated as XI on the Modified Mercalli Intensity scale which are described as very disastrous or extreme events which are likely to cause significant damage to structures.

The maximum measured intensity of the 2010 Canterbury earthquake in New Zealand was IX (9) on the Modified Mercalli scale.

The Modified Mercalli Intensity scale is used in the US to determine the severity of earthquake effects. Intensity ratings are in Roman numerals, I - meaning no people felt movement, all the way up to XII - where almost everything is destroyed.The amount of structural and geological damage done by an earthquake in a specific location determines an earthquake's intensity on the Mercalli scale. :)

The Richter scale determines earthquake magnitude by measuring how much the ground moves, and the Modified Mercalli Intensity Scale determines earthquake intensity based on damage to buildings and effects on humans.
The Modified Mercalli Intensity scale is used to measure the intensity of an earthquake based on its observed effects on people, buildings, and the natural environment rather than the seismic energy. It provides a qualitative assessment of the shaking and damage caused by an earthquake at a specific location.
The Richter scale measures the magnitude of an earthquake based on the seismic energy released at its source, providing a single value that quantifies its strength. In contrast, the Modified Mercalli Intensity Scale evaluates the effects of an earthquake on people, buildings, and the Earth's surface, assigning intensity levels based on observations and experiences. While the Richter scale offers a scientific measurement, the Modified Mercalli scale reflects the earthquake's impact and perception, which can vary by location and distance from the epicenter.
the modified mercalli scale was VII-VIII
