Mercalli values are determined by assessing the observed effects of an earthquake on people, buildings, and the environment. They are not directly calculated like seismic magnitude. Instead, Mercalli values are based on descriptive accounts and surveys to gauge the intensity of shaking at different locations.

The Mercalli Scale measures the intensity of an earthquake based on observations of its effects on people, buildings, and the environment rather than scientific instruments. It uses a set of criteria to determine the level of shaking and damage experienced at a specific location during an earthquake.
The Mercalli Scale does not rely on a machine for its measurements; instead, it is a qualitative scale that assesses the intensity of an earthquake based on observed effects and human experiences. Developed by Giuseppe Mercalli in 1902, it ranges from I (not felt) to XII (total destruction), evaluating factors such as damage to buildings, people's reactions, and changes in the Earth's surface. Seismologists often use reports from witnesses and structural damage assessments to determine the scale's rating after an earthquake occurs.
The Mercalli intensity scale ranges from I to XII, with higher numbers indicating more severe shaking and damage during an earthquake.
Richter scale, Modified Mercalli scale, Centigrade scale, and the Moment Magnitude 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 mercalli scale was made by Giuseppe mercalli he was born in milan.

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.
