- Coordinates: 55.5424° S, 28.8526° W
- Depth: 26 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 | 161° | 44° | 177° |
| 2 | 253° | 88° | 46° |
The data is preliminary (status: reviewed) and may be revised by USGS as additional information becomes available.
