In today’s interview, we talk with Prof John J. Clague, who was awarded the 2020 Sergey Soloviev Medal for his remarkable scientific contributions in fundamental and applied research on earthquakes, tsunamis, outburst floods and landslides, directed towards risk reduction for the benefit of societies. Hi John, can you please briefly introduce yourself, telling your main …[Read More]
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, …[Read More]
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 …[Read More]

The population of many countries in the world is exposed to earthquakes, one of the most destructive natural hazards. Sometimes, consequent triggered phenomena can be even worse than the earthquake itself. In this context, earthquake-induced landslides often concur in life and economic losses. To better understand these induced phenomena, updated catalogues of their types and …[Read More]
