May 11-25, 2016 – Second mission

Senza categoria

The mission will be mainly devoted to identifying and mapping landslides that represent a potential hazard affecting the Enguri reservoir lake.

Major efforts will also be taken in carrying out georadar analyses and investigating active tectonic structures, which may play a substantial role in increasing the degree of geological risk in the area.

 

NATO ENGURI Project training schools for young researchers

Senza categoria

Iceland, September 2016
This summer school has been held in northern Iceland, near the town of Husavik, where astonishing geological structures and landforms are exposed, which were produced by recent and historical earthquakes. Young researchers from Georgia, USA, Italy and Kazakhstan were trained on the study of Holocene tectonic fissures linked to the active Iceland Rift, strike-slip faults associated with the Husavik-Flatey transform fault zone, as well as on Quaternary volcanic deposits and landslides.

Georgia, Enguri, November 2016
Training activities were carried out in the field when senior scientists from the various project teams illustrated to young researchers from Georgia, Kazakhstan, Azerbaijan, USA and Italy, how to search for and interpret the field evidence of active landslide movements and neotectonic data.

University of Milan Bicocca and Istituto di Geologia Ambientale e Geoingegneria – Consiglio Nazionale delle Ricerche, Italy, Winter 2016-17.
Young researchers from Georgia have been trained in laboratory methods for the study of active deformations, microzonation and seismic hazard assessment, and interpretation of geophysical data. They spent up to six months in the aforementioned institutes.

Georgia, Enguri, May 2017
A training school on GPS measurements of active deformation has been carried out in the area of active landsliding above the Enguri reservoir (Georgia). This school saw the participation of young researchers from Georgia and Kazakhstan.

Georgia, Enguri, June 2018
A training school on GPS measurements of landslide motions has been carried out on the slope facing the Enguri reservoir (Georgia). This school saw the participation of young researchers from Georgia and Kazakhstan.

Media coverage

Our project drew the attention of the Italian and Georgian media. One of the two main Italian press agencies (AGI) issued a series of press releases on the web. Several other media outlets published news stories following the official AGI press release.

May 2016 – Third mission

Senza categoria

The third mission will be focused on landslide deformation measurements, landslide inventory, geomechanical characterisation of unstable slopes, and paleoseisimic measurements.
