Spatially Fixed Initial Break Point and Fault-Rock Development in a Landslide Area

The relationship between slip behavior and fault-rock properties has been investigated from several perspectives, including rock mechanics, landsliding, and earthquake faulting. This includes mainly studies on land, but recently also from submarine settings, since increasing availably of new offshore technologies allow marine fault/slip zone drilling and monitoring. Here we present a detail study for a subaerial landslide in SW Japan, the conceptual and methodological approach of which may provide important means towards better understanding various friction behaviors including ocean margin slope creeping and submarine landslides.
