Summary:

The shapes of typical Hawaiian volcanoes are simply parameterized, and a relationship is derived for the dependence of lava accumulation rates on volcano volume and volumetric growth rate. Therefore, the objective this study is to quantify the relationships between volcano growth rates, mantle plume structure, velocity of the Pacific plate relative to the plume, and the path of a volcano relative to the plume axis. As a result, this paper presents simple geometrical models for the growth of Hawaiian volcanoes where the models described allow the lava accumulation rate, which can be measured from drill core geochronology and other observations, to be used to evaluate the evolutionary stage of a volcano.
