The state, distribution and style of landslide movement. States of landslide activity can be active, suspended, reactivated and inactive. Distributions of landslide activity can be advancing, retrogressive, enlarging, diminishing, confined, moving, widening. Styles of landslide activity can be complex, composite, successive, single and multiple. Landslide activity can also be described as the stage of development of landslides. Pre-failure stage is when the slope is strained throughout but is essentially intact. Failure stage is characterized by the formation of a continuous surface of rupture. Post-failure stage includes movement from just after failure to when it essentially stops. Reactivation stage is when the slope slides along one or several pre-existing surfaces of rupture. Reactivation may be occasional (e.g. seasonal) or continuous (in which case the slide is ‘active’).

Abstract
Landslide research is an interdisciplinary field that primarily encompasses scientists from geomorphology, engineering geology, and geotechnical engineering in collaboration with researchers from such fields as geodesy, hydrogeology, geophysics, and many others. This chapter is intended as a resource for researchers interested in landslide engineering and landslide science to acquire a summarized review of research subjects and the state-of-the-art literature. A wide range of landslide topics are presented in the following sections: landslide mapping, landslide investigation, landslide monitoring, landslide hazard and risk assessment, and landslide stabilization and remediation measures. The results of landslide studies have practical applications to society via the avoidance, prevention, and mitigation of landslide hazards and risks. Landslide avoidance and prevention are the primary interests for land-use policies based on landslide mapping, followed by the prediction of landslide processes and their consequences. Landslide mitigation includes the development of engineering technologies for landslide investigation, monitoring, and remediation.
