Are mantle plumes stationary or do they move over time?

Auckland's volcanoes are powered by a 'hot spot' deep beneath the surface. The hot spot is a zone of magma fed by a plume of hot rock rising up out of the ... May 10, 1995 ... Here we show that recent estimates for the volume of hotspot volcanism and the size of the swell suggest a shared origin: swell relief is ... May 25, 2017 ... Abstract. Mantle plumes are buoyant upwellings of hot rock that transport heat from Earth's core to its surface, generating anomalous regions of ... hotspot ... hotspot, region of Earth's upper mantle that upwells to melt through the crust to form a volcanic feature. Most volcanoes that cannot be ascribed ... Mantle plumes and volcanic hotspots, distribution of hotspots, distribution of hotspots (Credits: K. Cantner, Earth Magazine), hotspot volcano chain Reunion. The southeastern extension of the Austral Islands volcanic chain terminates near 29°S, 140°W at the active Macdonald Seamount. The 'hotspot' region near ... This lies at a fixed position under the Tectonic Plate. As the plate moves over this “hot spot”, the upwelling lava creates a steady succession of new volcanoes ... Jul 3, 2016 ... The volcanoes of Hawaii, Iceland, the Galapagos and Yellowstone form from plumes of mantle beneath the surface, making them hotspot volcanoes. In an oceanic hotspot environment, for example Hawaii, dark, silica-poor basalt magma is produced. The runny basalt forms broad sloping shield volcanoes (Fig. 6) ... ... volcanism that is trailed by an age-progressive hotspot volcano chain. However, a range of observations call for significant extensions to classical theory ...
