Seismic network consisting of three small arrays (aperture roughly 30m) deployed along the ridge of Mt. Zugspitze to monitor permafrost dynamics with ambient noise. Each array is composed of one Trillium Compact 120s broadband sensor and five 4.5 Hz PE-6/B geophones. Two of the three arrays are installed in a man-made tunnel beneath the surface, sampling rate is 200 Hz. The network will be complemented with periodic rotation sensor deployments as well as periodic strain (rate) measurements through distributed acoustic sensing. For this purpose, we installed a roughly 2 km long fiber-optic cable in tunnels beneath the ridge of Mt. Zugspitze, which we interrogated every few months using a Silixa iDAS unit. Sampling rate is 500 Hz, spatial sampling 2 m. ...
