Abstract
The North Tabarca Fault, W-E striking, is the northern limit of the Tabarca anticline crest, separating it from the Alicante syncline. It is interpreted as a strike-slip fault that downthrown the northern block and, to the south, upthrown the basement formed by the Betic Internal Zone. It does not seem active at present because is fossilized by a lithoseismic unit dated between the Younger Dryas and Today. Two lithoseismic units interpreted as lower Messinian and upper Messinian separated by the intramessinian discontinuity are observed in the studied seismic profiles. The double reflector that separates the folded lithoseismic units from the horizontal ones has been interpreted as a lithification change.
