Weekly Seminar: “Dissemination activities related to the project: HEIMDALL”

15/03/2018 - 15/03/2018


This Seminar has as its central focus the subject  of the project “HEIMDALL: H2020-EU.3.7.5 (Increase in Europe’s resilience to crises and disasters), HEIMDALL – MULTI-RISK COOPERATIVE MANAGEMENT TOOL FOR DATA EXCHANGE, RESPONSE PLANNING AND CREATION OF SCENARIOS”
It is structured in two brief seminars, complemented by each other, as follows:

TITLE: “Catching geomorphological response in dynamic environments by means of advanced remote sensing techniques”


The most relevant aspect of present-day geomorphology in comparison with previous decades, is the massive use of the new technologies. The potential of very high-resolution remote sensing techniques to monitor earth surface and geomorphological processes has been emphasized by many studies. Remote sensing data comprises Synthetic Aperture Radar (SAR) imagery, very high resolution (VHR) Digital Elevation Models (DEMs), and VHR optical imagery. Interferometric SAR (InSAR) procedures will reveal ground displacement, whereas the analysis of both optical images and SAR amplitude data permits to map areas affected by major lithological and morphological changes. The volumes of deposited/eroded material can be estimated by means of DEMs subtraction. The focus of this talk is to show the potential of advanced, multi-platform remote sensing techniques as tools to monitor changing environments.


Federico Di Traglia, Ph.D., is a Post-doc fellow at the Department of Earth Sciences at the University of Firenze (Italy). He is currently Adjunct Professor of the “Geology and Geomorphology” class in the framework of the course “Environmental and Civil Engineering” at the Department of Environmental and Civil Engineering at the University of Firenze. His research deals with volcanic geomorphology and geology, remote sensing of volcanoes, and volcano slope instability assessment and hazard management. He was member of the scientific panel during the 2012-13, 2014, and 2017 eruptive crises at Stromboli volcano, supporting the National Civil Protection Department in the crisis management phases.


TITLE: “Using satellite and ground-based radar interferometry for early warning and forecasting of hydrogeological hazards”


It is difficult to estimate the risk represented by landslides on a global scale; safe evaluations consider that the average number of annual fatalities is more than 5000 per year worldwide, whereas the annual cost for some exposed Countries easily exceeds $1 billion. Projections based on the possible effects of climate change suggest that these numbers are probably bound to increase. Forecasting a catastrophic collapse is a key element in landslide risk reduction, but also a very difficult task, owing to the scientific difficulties in predicting a complex natural event and also to the severe social repercussions caused by a false or a missed alarm. In this talk we will encompass some of the most used time of failure forecasting methods, the new developments in this field and eventually we will discuss how the recent monitoring technologies allow us to improve our prediction capability.


Emanuele Intrieri, Ph.D., is a research associate at the Earth Sciences Department at the University of Florence. He is currently lecturer of the “Geotechnics” course at the same Departments and has been holder of “Fundamentals and applications of geology and geomorphology” teaching course at the Architecture Department. He was also lecturer at the 2nd level master “Expert in Forecasting/Prevention Hydrogeological Risk”, at the University of Calabria. His research is mostly devoted to landslide risk mitigation, with special reference to advanced monitoring (especially SAR apparatuses), early warning systems and failure forecasting methods.
