After the November 14, 2007 M7.7 Tocopilla earthquake in northern Chile, a local seismic network was installed in the rupture area between approximately Tocopilla and Antofagasta by the German Task Force for earthquakes (German Research Centre for Geosciences - GFZ) in order to record aftershocks. The network was composed of 20 mostly short period seismometers (L4-3D) and 5 strong motion instruments recording continuously with a sampling rate of 100 Hz; the average distance between these stations was ~15 km. Waveform data are available from the GEOFON data centre, under network code Y9 under CC-BY 4.0 license.
