One example of the Modified Mercalli Scale could be as follows:
An earthquake with a magnitude of 6.5 strikes a densely populated city. The ground shaking intensity is assessed using the Modified Mercalli Scale. Here is an example of how the scale could be applied in this scenario:
- Intensity I: Not felt. The earthquake is not felt by humans.
- Intensity II: Weak. Felt only by a few people at rest, especially on the upper floors of buildings.
- Intensity III: Weak. Felt noticeably indoors, especially by people on upper floors. Vibrations similar to passing trucks or heavy machinery.
- Intensity IV: Light. Felt indoors by many, outdoors only by a few. Hanging objects swing slightly.
- Intensity V: Moderate. Felt by most people. Some dishes, windows, and doors rattle. Small objects shift on shelves.
- Intensity VI: Strong. Felt by everyone. Furniture moves and walls crack. Pictures fall off walls.
- Intensity VII: Very strong. Damage occurs, especially to poorly constructed buildings. Chimneys may collapse and bridges may be damaged.
- Intensity VIII: Severe. Considerable damage in structures, including buildings partially collapsing. Large cracks in the ground may appear.
- Intensity IX: Violent. Many buildings are destroyed or heavily damaged. Ground cracks are widespread. Landslides may occur.
- Intensity X: Extreme. Most buildings collapse or experience severe damage. Ground cracks are significant and can be seen from the air.
- Intensity XI: Catastrophic. Few buildings remain standing. Landslides are widespread, and the ground surface is distorted.
- Intensity XII: Devastating. Total destruction. Objects are thrown into the air. The ground moves in a wavelike motion.
This scale helps scientists and emergency responders understand the level of impact an earthquake has had on an area and enables them to determine appropriate response measures.

An earthquake with a magnitude of 6.5 strikes a city. The Modified Mercalli Scale is used to assess the ground shaking intensity:
- Intensity I: Not felt.
- Intensity II: Weak, felt by a few people at rest.
- Intensity III: Weak, felt indoors on upper floors.
- Intensity IV: Light, felt indoors by many, outdoor only by a few.
- Intensity V: Moderate, felt by most people.
- Intensity VI: Strong, furniture moves, walls crack.
- Intensity VII: Very strong, damage occurs to poorly constructed buildings.
- Intensity VIII: Severe, buildings partially collapse, ground cracks.
- Intensity IX: Violent, many buildings destroyed, landslides possible.
- Intensity X: Extreme, most buildings collapse, widespread ground cracks.
- Intensity XI: Catastrophic, few buildings remain, widespread landslides.
- Intensity XII: Devastating, total destruction, objects thrown in the air.
This scale helps assess earthquake impact and determine appropriate response measures.
