Plate tectonics in the Pacific and Atlantic during the Cretaceous period shaped the Caribbean region
The concurrent subduction of the Pacific and Atlantic plates resulted in the formation of a mantle plum and the ascent of magma. Credit: Nicolas Riel Earthquakes and volcanism occur as a result of ...
Boulder, Colo., USA: GSA’s dynamic online journal, Geosphere, posts articles online regularly. Topics include Farallon plate subduction; 3-D digital outcrop scanning and modeling; and the Cerro Blanco ...
Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...
The driving force behind Yellowstone’s long and explosive volcanic history may not be as deep as once thought. A new study suggests that instead of a plume of hot mantle that extends down to Earth’s ...
After last week’s Geysers article I got two excellent questions: what causes volcanic activity in the Clear Lake area and how does waste fluid injection at The Geysers differ from what happens in ...
Going way, way back to the early Cenozoic Era, around 40 to 60 million years ago, there were two major tectonic plates – called the Kula and the Farallon – in the Pacific Ocean off the western coast ...
