Map showing locations of Orleansville earthquake, path of main turbidity current and submarine cables. Depths in fathoms. Note that the northernmost cables were not interrupted by the turbidity current. It is probable that several coalescing turbidity currents joined to produce the pattern of breaks indicated on this map. (After Heezen and Ewing, 1955.) B. Orleansville Turbidity Currents A series of cable failures on the floor of the western Mediterranean (Figs. 6, 7 and 8), essentially similar in distribution and order to the Grand Banks sequence, followed the 1954 Orleansville earthquake (Heezen and Ewing, 1955). These events further support the interpretation of the Grand Banks turbidity.
