Berkeley, Calif. (UPI) Sep 5, 2013 - U.S. scientists say they've made a discovery that helps explain Earth's "hot spot volcanoes" that give birth to island chains such as Hawaii and Tahiti. Unlike volcanoes that emerge at collision zones between tectonic plates, hot spot volcanoes form in the middle of the plates. Most current theories assume a single upwelling of hot, buoyant rock rises vertically as a plume from d ... morehttp://www.terradaily.com/reports/Seismic_finding_could_explain_creation_of_Earths_hot_spot_volcanoes_999.html
