Figure F5. Location predictions of the Louisville hotspot track based on Indo-Atlantic data transferred to the Pacific plate via global plate circuits. Red = standard plate circuit (Cande et al., 1995), with transfer from the Atlantic basin through West Antarctica (WANT) and East Antarctica (EANT), based on the present-day hotspot location at 50.9°S, 138.0°W (Lonsdale, 1988). Blue = alternate plate circuit (Steinberger et al., 2004), with a transfer through the Lord Howe Rise (LHR). Brown = alternate location of the present-day hotspot location at 53.5°S, 141.12°W (Epp, 1978; Wessel and Kroenke, 1997) (no reconstruction is shown for this alternate hotspot location). From J. Tarduno, R. Cottrell, and P. Doubrovine (Rochester University) (unpubl. data).
