Seismic and gravity data taken along line 1 of the 1982 Consortium for Continental Reflection Profiling (COCORP) Mojave Desert Survey (N-S profile, -30 km long) have been used to characterize the upper crust north of the San Andreas fault in the western Mojave block of southern California. Consortium for Continental Reflection Profiling seismic reflection data were reprocessed to emphasize the ...

The Algerian margin is located at the slow-rate convergent boundary between African and Eurasian plates experienced several strong earthquakes in last centuries. Among them, 2003 Mw 6.8 Boumerdès event has triggered large turbidity currents slightly concave canyons of slope numerous cable breaks abyssal plain. In this study, we explore where, how when tectonic inversion off left witnesses seafl...

This contribution considers the predictions of mass movements that have yet to take place and the support provided by spatial databases for the prediction. Conventional hazard maps tend to compile the neighbourhoods and dynamic types of the known past landslides, assuming that they satisfactorily represent the locations of future landslides. The latter, however, may also occur elsewhere. Spatia...

High-resolution bistatic images of a typical abyssal hill on the western flank of the Mid-Atlantic Ridge are made with a low-frequency towed-array system operating remotely at 1/2 convergence zone ~;33.3 km! stand-off. Comparison with modeled images, generated from high-resolution supporting bathymetry sampled at 5-m intervals, roughly the wavelength scale, reveals that steep scarps return the ...

6 [1] Clay-rich mass transport deposits (MTDs) in the Ursa Basin, Gulf of Mexico, record 7 failures that mobilized along extensional failure planes and transformed into long runout 8 flows. Failure proceeded retrogressively: scarp formation unloaded adjacent sediment 9 causing extensional failure that drove successive scarp formation updip. This model is 10 developed from three-dimensional seis...
