This presentation reviews the new data; from both geophysical and geological investigations, carried out through the Sidi-Abdellah microzoning project. As a whole, data indicate that the Mahelma Fault would be an earlier normal fault of the Mitidja basin. During basin inversion, this fault would have been reactivated recording reversal of movement from extension to reverse. This fault has attracted attention largely because its economic implication related to seismic hazard assessment, and because the Mahelma fault can inform us about the active tectonic of the major Sahel active fault.
