Average earthquake effects |
Average frequency of occurrence (estimated)
|
|
Less than 2.0
|
Micro |
Microearthquakes, not felt of felt rarely by sensitive people. Recorded by seismographs. |
Continual/several million per year |
|
2.0-2.9 |
Minor |
Generally felt by few up to many people. Weak shaking in the felt area. |
Over one million per year
|
|
3.0-3.9 |
Minor |
Often felt in the area by at least many people, but very rarely causes damage. |
Over 100,000 per year
|
|
4.0-4.9 |
Light |
Noticeable shaking of indoor items, rattling noises. Many people, or everyone, feel it with slight to strong intensity. Slightly felt outside. Generally causes none to slight damage. Some falling of objects. |

|
|
9.0-9.9 |

Destructive to very devastating in extremely large areas. Many to all buildings severely damaged to completely destroyed, even miles from the epicenter. Ground changes. Death toll usually between 250 and one million. |
One per 5 to 50 years
|
|
10.0+ |
Massive/Epic
|
