1993. He was a postdoctoral researcher at the University of California (UC) and the San Diego State University and UC San Diego, USA, from 2009 to 2013. From 1996 to 2002, Dr. Ray worked as a civil infrastructure engineer for the Government of Nepal, and from 1993 to 1996 he worked as a civil engineer at the TAEC Consult P. Ltd. He is a member of the American Society of Civil Engineering (ASCE), Soil Science Society of America (SSSA), and the American Geophysical Union (AGU). Dr. Ray's research interests include natural hazard (landslide and flood) and risk analysis using GIS/remote sensing and spatial statistical analysis, fluvial geomorphology, flood risk analysis, flood hazards, soil water dynamics, water resource management, hydrologic modeling, remote sensing, climate change, carbon sequestration, and precision agriculture. He has several peer-reviewed publications and book chapters on landslide hazards, flood prediction, soil moisture dynamics, carbon sequestration, drought, precision agriculture, climate, and land use/land cover change studies using remotely sensed data, model, and field experiments. He is editor and editorial board member of several journals including *Remote Sensing in Earth System Sciences*, *Remote Sensing*, *Agronomy*, *Civil Engineering*, *Constructions*, and others.

Dr. Maurizio Lazzari has a PhD in Earth Science and is a researcher at the Italian National Research Council, Institute of Cultural Heritage Sciences. Since 2001, Dr. Lazzari has been Professor of Pedology at the University of Basilicata (Italy) and a geoarchaeologist at the University of Salento (Italy). His research activities are focused on natural and anthropic hazard and risk factors, aimed at safeguarding and conserving settlements and

the historical–monumental heritage of the Mediterranean, with particular attention to landslide processes, susceptibility maps, monitoring, and modeling. Since 2004, he has been working as a scientific coordinator for several national research projects studying landslides and triggering factors, natural and anthropogenic risks, geological and geomorphological mapping, soil erosion, preservation of historical and archaeological sites, enhancement of degraded areas, geo-touristic use, and the protection of the landscapes. He is the author of about 150 scientific publications in national and international journals, monographs, book chapters, and conference proceedings concerning applied geology, geomorphology, dynamics of artificial reservoirs, soil erosion, landslides, geoarchaeology, hydrogeological instability, natural hazards, monitoring, cultural landscape, UNESCO Heritage, geoarchaeology, and geo-tourism.

This book provides the reader with a comprehensive overview of the current state of the art in landslide disasters, featuring an easy-to-follow format that focuses on the most important evidence-based developments in this critically important area.

Several authors, belonging to research and public institutions from different parts of the world, have collaborated in the technical discussion of this topic, reporting their experience and present advances in the critical research areas. The book contains nine chapters that cover important research aspects inherent to mapping,

The introductory chapter, **Chapter 1**, prepared by the editors, consists of an overview of "Landslide Hazards" that includes overarching concepts of importance to the study of landslides, including global landslide information, factors affecting

landslides, and recent trends and techniques used to investigate landslides. **Chapter 2**, prepared by Ram L. Ray, Maurizio Lazzari, and Tolulope Olutimehin, discusses remote sensing approaches and techniques used to study landslides and explores the possibilities of potential remote sensing tools that can effectively be used in landslide studies in the future. **Chapter 3**, prepared by Fabio Luino, and Laura Turconi, explains the unique translational rock-block slides located in Tertiary Flyschid Complexes of the Southern Piedmont Region (North-West Italy).

**Chapter 4**, prepared by Rocío N. Ramos-Bernal, René Vázquez-Jiménez, Sulpicio Sánchez Tizapa, and Roberto Arroyo Matus, characterizes susceptible landslide zones by using the accumulated index. This study helps to locate areas vulnerable to landslides and integrate disaster management or prevention plans. **Chapter 5**, prepared by Maurizio Lazzari, Marco Piccarreta, Ram L. Ray, and Salvatore

Manfreda, explains the role of antecedent soil moisture on critical rainfall intensityduration thresholds to evaluate the possibility of modifying or improving traditional

**Chapter 6**, prepared by Miau-Bin Su, I-Hui Chen, Shei-Chen Ho, Yu-Shu Lin, and Jun-Yang Chen, presents time-domain reflectometry (TDR) technology for a long-term landslide monitoring system to explore rock deformation mechanisms and detect the location and magnitude of slope movement. **Chapter 7**, prepared by Jónas Elíasson and Þorsteinn Sæmundsson, presents the use of the translatory wave model to study landslides. This chapter also includes three case studies to study submarine slides (Japan), rock avalanche (SE Iceland), and debris slides

(N Iceland) using the translatory wave model.

susceptibility, hazard and risk, monitoring, and modeling.

This book was born from the desire to offer to a broad audience of interested readers an overview of cognitive approaches to the study of landslides and the control of their evolution, through innovative integrated monitoring techniques. This subject is very topical, considering that landslides are one of the most destructive natural hazards, as they cause significant threats to lives, properties, and natural environments throughout the world, especially in mountainous

regions.
