ARGO-E GROUP staff has co-authored a new article published in the “Applied Sciences” journal.
In this publication, titled “Landslides Triggered by Medicane Ianos in Greece, September 2020: Rapid Satellite Mapping and Field Survey”, Prof. Dimitrios Zekkos and John Manousakis, Geomatics Engineer, along with lead author Dr. Sotiris Valkaniotis, and co-authors Prof. George Papathanassiou, Prof. Vassilis Marinos, Dr. Charalampos Saroglou, Vasileios Kallimogiannis, Efstratios Karantanellis, Ioannis Farmakis, Dr. Georgios Zalachoris and Dr. Olga-Joan Ktenidou, showcase a well-documented case study of field survey and rapid response through satellite imagery, following the landfall of Medicane Ianos, which hit Greece during 17–19 September 2020 causing numerous landsides and floods.
Characteristic damages in Cephalonia Island following Medicane Ianos: (a) Riverbank erosion,
(b) debris flow within a rural community, (c) road embankment failure, (d) extensive debris flow, and (e) bridge collapse.
A rapid landslide inventory for the Karditsa region was prepared using Copernicus Sentinel-2 satellite imagery, the first of its kind for a severe weather event in Greece. The mountainous area of Karditsa region in western Thessaly experienced the unprecedented number of 1696 landslides, mapped through satellite imagery and examined in the field. Cephalonia Island experienced a smaller number of landsides but damaging debris flows and severe structural damages. The rapid landside inventory was then compared to new methods of automated landslide mapping through change detection of satellite imagery.
