  1. AlpArrayMagnetotelluric MT Group at the GFZ 12E swath meeting, 18. Juli , 11:00 - 17:00

  2. Field Setups • Three-dimensional electrical conductivity structure of the entire Alps using MT array data • High-resolution electrical conductivity images of the Periadriactic Fault system (12E Swath)

  3. Total Cost: 660k€ • - Field experiment 150k€ • - 1 PostDoc (36 PM, TvÖD13) 225k€ • - 1 PhD (36 PM, TvÖD13, 75%) 169k€ • - 4 Student helper (36PM) 56k€ • - Travel 60k€. Regional Scale • Key points: • Imaging lower crust uppermost mantle: • Transition from the western to the eastern Alps. • Active and fossil fault systems. • Provide boundary values for further localized MT experiments.

Moorkamp ETH Zurich: A. Kuvshinov CNR – IGG: Adele Manzella • Field Setup: • - ~ 160 sites, 40-50 km site spacing • Long period data  recording time ~ 1 month. • Instruments  National German Instrument Pool (GIPP-MT)

  4. Local Scale • Key points: • Imaging crustal structures including: • Shear zones: possible pathways for mantle fluids, • active and fossil fault systems, • the boundary between the European and Adriatic plates. • - ~ 2 km km site spacing • Broad Band data  recording time 3-4 days. • The duration of the field experiment: 6-8 weeks. • Total cost: 313k€ • - Field experiment 100k€ • - 1 PhD (36 PM, TvÖD13, 75%) 169k€ • - 1 Student helper (36PM, 40h/month) 14k€ • - Travel 30k€.
