AlpArray Field Activity: SWATH D Project in SSP 4D-MB Mountain Building in four dimensions

This project is designed to collect and provide seismological data through a dense seismological network in the central and eastern Alps. The 154 densely spaced stations planned here will complement the larger-scale AlpArray Network ("backbone"). SWATH D focuses on a key region of the Alps where the polarity of the subduction may change and where TRANSALP found a jump in the Moho. The data generated in this project are required by 15 individual applications in the SPP; 15 other proposals need products (e.g. tomographic images) resulting therefrom. SWATH D is therefore an important part within the SPP and the international AlpArray community, as well as a scientific service for the majority of the projects in the SPP.

Planned station distribution within Swath D (red box). The 153 stations cover an area of about 120 x 315 km^2, with an average station spacing of 15 km. Gaps in the station distribution are filled by stations of the larger international AlpArray Seismic Network or permanent stations. For reference, the track of the legacy TRANSALP experiment is shown.
