Understanding Earthquake Magnitude
Magnitude measures the strength of an earthquake. The official term for this measurement is the moment magnitude scale. This scale is logarithmic, indicating that each whole number increase represents a tenfold increase in measured amplitude and roughly 31.6 times more energy release.
Magnitude Scale Breakdown
| Magnitude Range | Description |
|---|---|
| Below 2.5 | Generally not felt |
| 2.5 to 5.4 | Minor or no damage |
| 5.5 to 6.0 | Slight damage to buildings |
| 6.1 to 6.9 | Serious damage |
| 7.0 to 7.9 | Major earthquake; serious damage |
| 8.0 or greater | Massive damage; can destroy communities |
This earthquake highlights the potential dangers associated with seismic activity in Alaska. Residents are advised to stay informed and follow safety protocols during such events.
