Abstract A smooth subducting seafloor usually leads to a smooth megathrust, which promotes great earthquakes. We present a case study at the northern Manila Trench to emphasize that the process depends also on sediment accretion and deformation. Here

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 19, Iss 8, Pp 2342-2370 (2018)

Abstract The role of seafloor roughness on the seismogenic behavior of subduction zones has been increasingly addressed over the past years, although their exact relationship remains unclear. Do subducting features like seamounts, fracture zones, or

International audience; We have developed a new approach to characterize the seafloor roughness seaward of the trenches, as a proxy for estimating the roughness of the subduction interface. We consider that abrupt elevation changes over given wavelen

Compressibility behaviour of lime-treated marine clay

Autor: G. Rajasekaran, S. Narasimha Rao

Publikováno v: Ocean Engineering. 29:545-559

The necessity to tap natural marine resources from the ocean beds represents a considerable challenge for the construction of offshore structures on weak marine deposits. The use of lime to improve the behaviour of soft clays is not new. The present
