They showed that the ridge lies close to a great circle connecting the Tonga-Kermadec trench with the Eltanin Fracture Zone. The chain may have been formed by movement of the Pacific Plate over the Louisville hotspot or by leakage of magma from the shallow mantle up through the Eltanin fracture zone, which it follows closely. The inferred circulation around the trough is clockwise. Please click on … GeoNames.

Lett., in press Computer-generated bathymetric map of a portion of the S-central Pacific, showing the Eltanin and Udintsev Fracture Zone systems, and the prominent seamount at about 53.9°S, 140.3°W in the epicentral area of the March 1991 swarm. In the Atlantic Ocean most fracture zones originate from the Mid-Atlantic Ridge, which runs from north to south, and are therefore west to east oriented in general. There are about 300 fracture zones, with an average north-south separation of 55 kilometres (34 mi): two for each degree of latitude. How were the British Isle (Great Britian) formed. The continuity in smooth trend of the ridge and the Eltanin Fracture Zone suggests some relationship between them. The two major faults in the Eltanin Fracture Zone are the Heezen Fault and the Tharp Fault.

The Hollister Ridge is a major volcanic system located on the Western flank of the Pacific–Antarctic Ridge (PAR), … The seismic history of the Eltanin Fracture Zone on the Pacific-Antarctic Ridge for the years 1920-81 shows that the seismic slip accumulated during this recording interval accounts for only a small fraction (<10%) of the amount of slip predicted by kinematic models of plate motion. The term fracture zone is used almost exclusively for features on oceanic crust; similar structures on continental crust are instead termed transform or strike slip faults, a denomination active fracture zones also can have. Some fracture zones have been created by mid-ocean ridge segments that have been subducted and may not longer exist. On the Egyptian continental shelf, in the Mediterranean Sea, at approximately the midpoint between the two outlets of the Nile at Masabb Rashid and Masabb Dumyat.
