On 17 June 2026, 18:56 UTC, an earthquake of magnitude M6.6 was recorded in the region: central Mid-Atlantic Ridge.
- Coordinates: 0.5458° S, 20.0163° W
- Depth: 10 km
The blue and white areas of the diagram show the directions of compression and extension during the rupture; the shape indicates the fault type (normal, reverse, or strike-slip). The solution yields two mathematically equivalent fault planes — which one is the actual rupture plane is usually unknown without additional geological context:
| Plane | Strike | Dip | Rake |
|---|---|---|---|
| 1 | 259° | 85° | -171° |
| 2 | 168° | 81° | -5° |
The data is preliminary (status: reviewed) and may be revised by USGS as additional information becomes available.
