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