This book gathers the proceedings of the 2nd International Workshop on Natural Hazards (NATHAZ'19), held in Lajes do Pico, Pico Island, Azores in 2019. Natural hazards constitute the threat of a naturally occurring event having a negative effect on human beings. These effects are often called natural disasters. Among the natural hazards and potential disasters to be considered are: earthquakes, volcanic eruptions, landslides, subsidence, floods, droughts and coastal erosion. In addition, there are anthropogenic hazards that occur as a result of human interactions with the environment. They include technological hazards, which occur due to exposure to hazardous substances in the environment. Grasping the behaviour of natural systems requires a comprehensive understanding of climatology, geology and hydrology data and dynamics. Thus, it is important to conduct hazard and risk assessment studies for meaningful hazard mitigation. Further, the book demonstrates that an accurate understanding of natural systems and interactions between engineering and natural resources is of vital significance to the entire socio-economic sector. This volume offers an overview of natural hazards in model regions in Europe, America, and Atlantic islands. Providing new insights on the characterisation, assessment, protection and modelling of geological hazards, water systems, urban areas and coastal zones, it represents a valuable resource for all researchers and practitioners in the fields of Geosciences, Hydrology, Water Resources, Natural Hazards, Environments and Engineering. Main topics include:1. Natural Hazards and Disasters2. Sustainable Water Systems and Climate Change3. Technological Hazards and Engineering Design

Francisco Fernandes F. Fernandes is a skilled Engineer, with over 22 years of experience in practice and research in civil engineering. After an internship at the 'Sociedade de Empreitadas e Trabalhos Hidráulicos' he began his career in 1997 in budgeting and cost control at Engil. He was also a controller and responsible for several management areas at Eng. Luís Gomes company. He worked as a project manager in the Marques, Engil and Eng. Luís Gomes companies, and as director of production. Senior Member of the Institution of Portuguese Engineers has a master's degree in Business Administration and Management from the University of the Azores (2003), is Qualified Expert in the Energy Certification System (SCE-RCCTE), ADENE (Agency for Energy and Technical Superior of Safety and Hygiene of Work - Level 5). Other activities include participation in various courses, seminars and vocational training actions in the fields of engineering, safety and hygiene at work, energy certification and management, as a designer and qualified expert of the energy certification system. Presently, since 2012 he is Head of the Regional Laboratory of Civil Engineering in Azores. Currently, he is a board member of the Portuguese Seismic Engineer Society (SPES) and a member of the Fiscal Council of the Fund for the Development of Construction Sciences. As president of the organizing committee, he was responsible for several scientific events, namely the 10th Portuguese Congress of Seismology and Earthquake Engineering, the 16th Portuguese Geotechnical Congress, the 6th Luso-Spanish Geotechnical Conference and the I International Workshop on Natural Hazards. Currently, is in Organizing Committee of the International Workshop "Natural Hazards - Hydrological Risks" (LREC, Pico Island, Azores, May 2019).Ana MalheiroA. Malheiro is a skilled Geologist with 34 years of experience in practice and research in engineering geology, geotechnics and geological hazards. She studied Geology at the Faculty Sciences of the University of Lisbon in 1983 and received her master's degree at the University of Azores in Volcanology and Geological Risks in 2002.She works since 1984 in the Regional Laboratory of Civil Engineering where she responsible for the areas of engineering geology, in situ geological and geotechnical investigations, geotechnics and geological risks. She was Head of the Division of Ports (1995/1998) and since 1998 until now, she is Director of Services of the Department of Geotechnics and Exploration. She participated in several Coordination Commissions for Management Plans (namely Regional Plans and Municipal Plans). In addition, was also invited assistant lecturer (1985/1990; 1996/1999) at Azores University. She participated in several organizing committees for National and international Congresses and Workshops, as well as Scientific Commissions (e.g. 15th World Conference on Seismic Engineering, Lisbon, 2012, 5th, 9th and 10th National Congress of Seismology and Seismic Engineering, respectively in 2001, 2014 and 2016; 16th National Congress of Geotechnics, 2018). Currently, is in Organizing Committee of the International Workshop "Natural Hazards - Hydrological Risks" (LREC, Pico Island, Azores, May 2019). She has been co-authored several publications in indexed journals, conference proceedings/full papers, book chapters, technical, professional papers and technical reports. She co-edited 1 special volume "Volcanic Rocks" (Taylor & Francis). In general, technical reports they focus on the field of in situ geological-geotechnical investigations to support the larger constructions built in the Azores region, coastal erosion, slope stability; as well as, the evaluation of resources in quarries, evaluation of geological and/or geotechnical problems and the assessment of geological haza
