What evidence links hotspot volcanism to past climate change events?

Although most volcanic rocks are generated at plate boundaries, there are a few exceptionally active sites of volcanism within the plate interiors. These ... Nov 12, 2018 ... Volcanoes form far away from plate boundaries due to hotspot volcanism. Here, hot material rises from the Earth's interior via a so called plume towards the ... Mantle plumes and volcanic hotspots, distribution of hotspots, distribution of hotspots (Credits: K. Cantner, Earth Magazine), hotspot volcano chain Reunion. A hotspot is an area of the Earth's mantle from which hot plumes rise upward, forming volcanoes on the overlying crust. Jan 1, 2020 ... We examine swell bathymetry and island drowning at 14 hotspots and find a correspondence between island lifespan and residence time atop swell bathymetry. A volcanic hotspot is where magma pushes up from under the mantle and creates a volcano. The earth's plates move along and another volcano is created later. Feb 7, 2013 ... INTRODUCTION. In the framework of the hotspot concept, intraplate volcanism is typically related to stationary melting sources. Volcanoes grow above hotspots. A hotspot is a zone of melting above a mantle plume. · Hotspot volcanoes are better able to penetrate oceanic crust than ... Jan 30, 2025 ...
