Thus, a long-lived region of melt escape could have been sustained. Three of the earliest recorded observers of the volcanoes were the Scottish scientists Archibald Menzies in[26] James Macrae in[27] and David Douglas in This magma then makes its way to the surface, where it is erupted as lava.

Dana concluded that the Hawaiian chain consisted of two volcanic strands, located along distinct but parallel curving pathways. He also suggested that many other island chains in the Pacific showed a similar general increase in age from southeast to northwest.

Wilson proposed that mantle convection produces small, hot buoyant upwellings under the Earth's surface; these thermally active mantle plumes supply magma which in turn sustains long-lasting volcanic activity. However, it has been shown that other plumes display highly variable surface heat fluxes and that this variability may be due to variable hydrothermal fluid flow in the Earth's crust above the hotspots.

The composition of the volcanoes' magma has changed significantly according to analysis of the strontium — niobium — palladium elemental ratios. Pu'u 'O'o is one of the most active volcanoes in the world, and has been continuously erupting since January 3, Most notably, Dutton established that the island of Hawaii actually harbored five volcanoes, whereas Dana counted three.

Dietz and his colleagues first identified the swell behavior. The local tectonic plate in the case of the Hawaii hotspot, the Pacific Plate slowly slides over the hotspot, carrying its volcanoes with it without affecting the plume.

The large difference between the youngest and oldest lavas between Emperor and Hawaiian volcanoes indicates that the hotspot's velocity is increasing.

Prior to the bend, the hotspot migrated an estimated 7 centimeters 2. Pele's mythical flight, which alludes to an eternal struggle between volcanic islands and ocean waves, is consistent with geologic evidence about the ages of the islands decreasing to the southeast.

Data demonstrate vertical variability in the amount of strontium present in both the alkalic early stages and tholeitic later stages lavas.


In comparison, the average production rate at a mid-ocean ridge is about 0. Just reaching the summits proved daunting: The rate along the Emperor seamount chain averaged about 0.


The magma's original temperature was found in two ways, by testing garnet 's melting point in lava and by adjusting the lava for olivine deterioration. The process continues until the mantle plume itself collapses. The most rapid decrease in elevation and the highest ratio between the topography and geoid height are over the southeastern part of the chain, falling with distance from the hotspot, particularly at the intersection of the Molokai and Murray fracture zones.


Hawaiian lava spills out of craters and forms long streams of glowing molten rock, flowing down the slope, covering acres of land and replacing ocean with new land. The project drilled DetroitNintokuand Koko seamountsall of which are in the far northwest end of the chain, the oldest section.
