Factors Influencing Occurrence, Scale, Mobility, Runout, and Morphology of Mass Movements on the Continental Slope
Abstract
Achieve an improved understanding of the relationships between sedimentation, environment, and the morphology of continental slopes. This goal will be accomplished primarily through investigations within the northern California (Eel River) study area. An underlying assumption of our work is that the occurrence and morphology of mass movement features on the continental slope depend upon a combination of characteristics, each of which varies over the region in a consistent manner. We will apply data from other ongoing studies to augment and expand the usefulness of our information obtained in the northern California study area. Our work is closely coordinated with the geotechnical group at Laval University (Dr. Jacques Locat), but for administrative reasons, our work is funded separately by ONR. Identify and measure factors, such as steepness, seismicity, sediment strength, and pore pressure, that can be mapped regionally and that determine where and how slope failures occur. Derive a basis for producing regional maps that indicate relative landslide susceptibility. Evaluate the circumstances under which mass movements determine the steepness of the continental slope and contrast these circumstances with those in which the steepness is controlled by other factors.
