Home > Hotspot (geology)
In geology, a hotspot is a location on the Earth's surface that has expreienced active vulcanism for a long period of time. J. Tuzo Wilson came up with the idea in 1963 that volcanic chains like the Hawaiian Islands result from the slow movement of a tectonic plate across a "fixed" hot spot deep beneath the surface of the planet. Originally thought to be caused by a narrow stream of hot mantle convecting up from the mantle-core boundary called a mantle plume [1], the latest geological evidence is pointing to upper-mantle convection as a cause [2][3]. Geologists have identified some 40-50 such hotspots around the globe, with Hawai‘i, Yellowstone, and Iceland overlying the most currently active.List of hotspots
