Slow-moving landslide risk assessment combining Machine Learning and InSAR techniques

CATENA, 2021
This paper describes a novel methodology where Machine Learning Algorithms (MLAs) have been integrated to assess the landslide risk for slow moving mass movements, processes whose intermittent activity makes challenging any risk analysis worldwide.
