The present dataset is a high-resolution earthquake catalog for the region of the 2014 M8.1 Iquique earthquake sequence, in the Northern Chile subduction zone. Events in the catalog were obtained processing seismic waveforms from >100 permanent and temporary seismic stations. The list of waveform data sources used, the multistage automatic earthquake detection and location procedure implemented to build the catalog, as well as the patterns outlined by the seismicity are described in Soto et al. (2019). The dataset file contains information of hypocenters (one event per line), structured in a format with the following columns: # year, month, day, hour, minute, second (UTC), longitude [dec. degrees], latitude [dec. degrees], depth [km], magnitude [ML] Seismic waveform data were taken from networks CX (GFZ and CNRS-INSU, 2006), IQ (Cesca et al., 2018), 3D (Asch et al., 2014) and GE (GEOFON, 1993) accessed via EIDA webservices (e.g., https://geofon.gfz-potsdam.de/), as well as from Chilean Seismological Network (C, C1) stations (Barrientos et al., 2018) accessed via IRIS webservices (http://ds.iris.edu/SeismiQuery/). Additional waveform data were used from the MEJIPE temporary network deployed by FU Berlin (Salazar et al., 2013) accessed via EIDA webservices as well as from a temporary network deployed by the Chilean ONEMI, DGF and CSN institutions accessed from CSN upon request.
