| Magnitude | Description | Mercalli intensity | Average earthquake effects | Average frequency of occurrence (estimated) |
|---|---|---|---|---|
| Less than 2.0 | Micro | I | Microearthquakes, not felt, or felt rarely by sensitive people. Recorded by seismographs.[SUP][16][/SUP] | Continual/several million per year |
| 2.0–2.9 | Minor | I to II | Felt slightly by some people. No damage to buildings. | Over one million per year |
| 3.0–3.9 | II to IV | Often felt by people, but very rarely causes damage. Shaking of indoor objects can be noticeable. | Over 100,000 per year | |
| 4.0–4.9 | Light | IV to VI | Noticeable shaking of indoor objects and rattling noises. Felt by most people in the affected area. Slightly felt outside. Generally causes none to minimal damage. Moderate to significant damage very unlikely. Some objects may fall off shelves or be knocked over. | 10,000 to 15,000 per year |
| 5.0–5.9 | Moderate | VI to VIII | Can cause damage of varying severity to poorly constructed buildings. At most, none to slight damage to all other buildings. Felt by everyone. Casualties range from none to a few. | 1,000 to 1,500 per year |
| 6.0–6.9 | Strong | VII to X | Damage to many buildings in populated areas. Earthquake-resistant structures survive with slight to moderate damage. Poorly-designed structures receive moderate to severe damage. Felt in wider areas; up to hundreds of miles/kilometers from the epicenter. Damage can be caused far from the epicenter. Strong to violent shaking in epicentral area. Death toll ranges from none to 25,000. | 100 to 150 per year |
| 7.0–7.9 | Major | VIII or greater[SUP][17][/SUP] | Causes damage to most buildings, some to partially or completely collapse or receive severe damage. Well-designed structures are likely to receive damage. Felt in enormous areas. Death toll ranges from none to 250,000. | 10 to 20 per year |
| 8.0–8.9 | Great | Major damage to buildings, structures likely to be destroyed. Will cause moderate to heavy damage to sturdy or earthquake-resistant buildings. Damaging in large areas, some totally destroyed. Felt in extremely large regions. Death toll ranges from 100 to 1 million. | One per year (rarely none, two, or over two per year) | |
| 9.0–9.9 | Severe damage to all or most buildings with massive destruction. Damage and shaking extends to distant locations. Permanent changes in ground topography. Death toll ranges from 1,000 to several million. | One per 5 to 50 years | ||
| 10.0 or greater | Epic/Massive | X or greater | Total devastation; damage extends to distant areas. Landscape and elevation changes permanently. Death toll usually over 100,000. | Never recorded (unknown/may be impossible) |
