| Description | This multi-sensor seismic network was deployed to characterize the internal structure and monitor the deformation dynamics of the large-scale Cuolm da Vi (CdV) landslide, located near Sedrun in the Graubünden region of central Switzerland. The network combines a temporary hexagonal-grid array of >1,000 autonomous 1-component nodal seismometers with a 6.5 km trenched fibre-optic cable configured for both Distributed Acoustic Sensing (DAS) and Distributed Strain Sensing (DSS). Fibre-optic acquisition included continuous multi-month campaigns as well as controlled-source (dynamite) surveys. Since 2022, data acquisition has spanned multiple years to date and continues on a semi-permanent basis. Due to the large data volume (over 60 TB), a decimated version of the dataset is planned for public release in 2026. Subsets of the raw non-decimated data are available upon reasonable request. |
