Scientific paper

Geoid and topography over the Pacific Ocean are filtered to enhance small and intermediate wavelength. The filtered maps and rotations characterizing the absolute motion of the Pacific Plate are used to discuss the origin of lineaments coinciding with tracks issued from spots of known recent volcanism. It is concluded that the convective pattern beneath the plates consists of numerous rising plumes. Lineaments separated by about 200 km are the most remarkable feature over this wavelength range. Numerous additional lineations are shown to be parallel to hotspot tracks which seem to indicate that the lineations are due to magmas implaced just above or within the lithosphere. The lineation pattern is compared with the computed tracks for a set of tentative new hotspots. Results indicate that numerous plumes, long-lived and fixed with respect to each other provide an explanation of the observed small wave-length geoid features.
