Shaking Intensity
What the Shaking Levels Mean
Felt reports describe shaking on the Modified Mercalli Intensity scale, written in Roman numerals. It measures what people noticed where they were, not the size of the earthquake, so one earthquake brings different levels to different towns.
- Weak (II–III)
- Felt by a few people at rest, especially on upper floors, or noticeably indoors like a passing truck. Many people don't recognize it as an earthquake.
- Light (IV)
- Felt indoors by many people. Dishes, windows and doors rattle, walls creak, and it can feel like a heavy truck hitting the building.
- Moderate (V)
- Felt by nearly everyone and wakes many. Some dishes and windows break, and unstable objects tip over.
- Strong (VI)
- Felt by everyone. Some heavy furniture moves and plaster can fall, but damage is slight.
- Very Strong (VII)
- Little damage in well-designed buildings, slight to moderate in ordinary ones and considerable in poorly built ones.
