, such as the Hawaiian chain, may form from magma plumes, called hot spots, that are believed to rise from the core-mantle boundary. An example of a continental hot spot is found atYellowstone National Park, though the source of its magma may be from an ancient subducted tectonic plate....

Mount St. Helensis an active volcano located in Washington State, USA. It is part of theCascade Range, a mountain range running along the western side of North America from British Columbia in Canada to northern California, USA. Mount St. Helens was named after a British diplomat by explorer...
These provide the basis for the sensitivity analyses for each field and the affect of boundary definition is assessed using exploratory methods (summary statistics) and spatial intensity estimates. Harrat Rahat Harrat Rahat is one of at least nineteen volcanic fields within the western Arabian Plate ...
Recent geological and geophysical research indicates the presence of three volcanic systems in the Hengill-Grensdalur area and progressive westerly migration of the accretionary plate boundary. The Hengill system comprises the active Hengill central volcano and a NNE trending fissure swarm that is the ...
17,29,38). This is would be thus similar to the upper crustal Plate Boundary conditions in southernmost Patagonia along the Magallanes Fault where deformation is more localised along several, subparallel structures in the south that splay apart further north35. Clearly future high resolution remote...
(MgO=0.28%~1.04%).The A/CNK values range from 1.07 to 1.41, indicating peraluminous high-K calc-alkaline characteristics.The REE distribution curve shows a "V" shape.Large ion lithophile elements and high field strength elements Rb, K, and Th are relatively enriched, while Nb、Ta、Sr and...
We present one of the first studies on source location determination for volcanic earthquakes and characterization of volcanic subsurfaces using data from a distributed acoustic sensing (DAS) system. Using the arrival time difference estimated from well-
