High-resolution seismic constraint on the seafloor sediments using teleseismic body waves of ocean bottom seismometers in the regions of the Pacific ocean
Title: High-resolution seismic constraint on the seafloor sediments using teleseismic body waves of ocean bottom seismometers in the regions of the Pacific ocean Abstract: Ocean Bottom Seismometers (OBSs) have been extensively used to constrain the lithosphere- asthenosphere system of the oceanic plates. However, the signals from the seawater above and the seafloor sediment beneath the […]
Thermal control on the location of the volcanic arc at subduction zones
Thermal control on the location of the volcanic arc at subduction zones Goeun Ha, University of Maryland Subduction zones feature a line of volcanoes parallel to the trench forming a volcanic arc. The location of the volcanic arc is primarily controlled by a melt focusing mechanism that obeys the thermal structure of the overriding plate, […]

Stratovolcanoes form conical mountains by ejecta and lava, while caldera volcanoes have […]
The lithosphere-asthenosphere boundary and the Gutenberg discontinuity: The role of water, CO2 and melt
The Lithosphere-asthenosphere boundary and the Gutenberg discontinuity: The role of water, CO2 and melt Satish Singh, Institut de Physique du Globe de Paris, University of Paris City, France The plate tectonics theory is based on the concept of a rigid lithospheric plate floating over a weak, deformable and convecting asthenosphere, separated by a boundary termed […]
