In the frame of the DFG Buendelantrag (PAK262)"Megathrust seismicity and upper plate response-deformation transients of the subduction earthquake cycle" our project: "Physics and structure of subduction-induced geodynamic transients in terms of reflection seismic and micro seismological signatures" will observe the seismicity with a local seismological net in the area of the Salar Grande in Northern Chile.Results of this project will contribute to the following issues: Eartquake cycle, Fault related seismicity (Atacama Fault Zone), Non volcanic tremors, Earthquake swarms.
