The main subject of this study is “New faults from the geodynamics of South Katanga in D.R.Congo “
We suggested investigating in D.R.Congo, if it is possible to discover new or other intraplate faults
which can have relationship with the Rift Valley. This request is very important because many
discovered faults in the Great Lakes Region are interplates and ranged along of the Rift.
Therefore, a systematic analysis of the seismicity of DR Congo is made using data from local and
international observatories as IRSAC or CRNS, ISC, ISS and USGS.
The seismic map of D.R.Congo was built for a period of 105 years from 1910 to 2015.
So, the focal mechanism of last the earthquake in this region was reassessed to determine the direction
of tension axis, type of faults and correlation which exist between seismicity and the geodynamic of
this region. The result of focal mechanism shows that the associated type of fault is normal fault.
However, 1 zone was selected as ROI in Katanga, in order to discover if possible, the intraplate faults
which could have tectonic implication from Rift Valley. After analysis of satellite images (Landsat 8),
and aeromagnetic data from GECOMIN, 12 intraplate new faults were found in the chosen zone (Z1).
But the results show that the intraplate faults of Z1 are not directly connected to the Rift but it is
possible they come from special geologic processes of this region.
