Abstract Many models describing the Earth’s magnetic field exist and are maintained by international research organizations. However, no clear general overview of the cross-compared quality of these models is available. An evaluation of the interna

Marine magnetic data extracted from the geophysical database of the SHOM (the French Hydrographic and Oceanographic Service) offer a first overview of the magnetic offshore environment in the Gulf of Saint-Malo (Brittany, France). Their cross-interpr

Landslides and spreading of oceanic hot-spot and arc shield volcanoes on Low Strength Layers (LSLs): an analogue modeling approach

Autor: Philippe Labazuy, Jean-François Oehler, Benjamin van Wyk de Vries

Publikováno v: Journal of Volcanology and Geothermal Research. 144:169-189

During their growth and evolution, oceanic hot-spot and arc shield volcanoes are destabilized and often dismantled by landslides. The origin of these phenomena can be found in the structure of volcanic islands marked by several low strength horizons

International audience; Erosion processes on active volcanoes in humid climates result in some of the highest sediment yields on Earth. Episodic sediment yields after large eruptions have been evaluated, but not the long-term and continuous patterns
