How satellites measuring soil moisture provide a new understanding of rainfall patterns

How satellites measuring soil moisture provide a new understanding of rainfall patterns

Soil moisture and rainfall are the two fundamental variables in the water and energy cycle and their knowledge in many applications is crucial. For instance, for predicting the occurrence and the magnitude of flood and landslide events the knowledge of the initial soil moisture condition and of rainfall amount is mandatory. In the last decade, some authors have proposed a completely new approach, ...[Read More]

The Italian catalogue of earthquake-induced ground failures: saving the past for the future seismic hazard assessment #CEDIT

The Italian catalogue of earthquake-induced ground failures: saving the past for the future seismic hazard assessment #CEDIT

  The Italian Catalogue of Earthquake-Induced Ground Failures (CEDIT) is a database available online since January 2013 that stores data about ground failures induced by strong earthquakes, which occurred on the Italian territory since 1000 AD up to now. CEDIT is freely available on a web-GIS portal (currently the access is granted using Firefox as a web browser, the upgrade to other browsers ...[Read More]

InSAR Norway: the big eye on Norwegian unstable rock slopes

InSAR Norway: the big eye on Norwegian unstable rock slopes

Marie Keiding is a researcher in the Geohazard and Earth Observation team at the Geological Survey of Norway. Together with her colleague, John Dehls, who is leading the project, she works to develop and operate the new mapping service called InSAR Norway. Before we start, let’s briefly describe what is InSAR. First, the Synthetic Aperture Radar (SAR) is a day and night operational imaging system ...[Read More]

Anthropogenic changes of the landscape and natural hazards

In this post, I had the pleasure to interview Paolo Tarolli, a very active member of the EGU community and a brilliant scientist. He is Professor in Water Resources Management and Integrated Watershed Management, and head of Earth Surface Processes and Society research group at the Università degli Studi di Padova (Italy). He has a PhD in Environmental Watershed Management and Geomatics and has wo ...[Read More]
