- •
A new structural map of the Kivu rift was produced using DEMs and bathymetric data.
- •
The new map was compared to existing maps and validated with field data.
- •
Results suggest that rifting reactivated NE-oriented inherited crustal structures.
- •
NE-oriented structures influenced the location and distribution of volcanism.
- •
Magma underplating might explain part of the complex rift basin morphology.
