How common is a 7.0 earthquake?
Learn more about how we measure earthquake magnitude….Earthquake Magnitude Scale.
| Magnitude | Earthquake Effects | Estimated Number Each Year |
|---|---|---|
| 7.0 to 7.9 | Major earthquake. Serious damage. | 10-15 |
| 8.0 or greater | Great earthquake. Can totally destroy communities near the epicenter. | One every year or two |

What is a 6 on the Richter scale?

Is 6.0 A big earthquake?
The Richter magnitude scale, also known as the local magnitude (M) scale, assigns a number to quantify the amount of seismic energy released by an earthquake….What is the Richter Magnitude Scale?
| Richter magnitude | Description | Earthquake effect |
|---|---|---|
| 6.0-6.9 | Strong | Can be destructive in areas up to about 160 kilometres (100 mi) across in populated areas. |
What is a 10 on the Richter Scale?
No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake” in its own right.
