Volcanic structures on the seafloor off the NW African coast between 25°N and 32°N were imaged by GLORIA side scan sonar and SIMRAD EM12 multibeam bathymetry. The newly discovered Las Hijas Seamounts, located 70 km south-east of Hierro, are interpreted as young volcanic edifices. Their location is consistent with the spacing and timing of propagation of volcanism of the Canary Archipelago and may represent future sites of volcanic islands.
