Abstract:
This dataset includes earthquake locations from a 23 months long Ocean Bottom Seismometer (OBS) experiment conducted in response to the 2014 Mw 8.1 Iquique earthquake at the northern Chilean subduction zone. The experiment is separated into two subsequent OBS networks from December 2014 until October 2016. The accompanying zip-file SEISAN_WAV.zip includes raw waveform data for all earthquakes, the file Nordic.nor (ASCII Table) that includes all phase onset picks of all earthquakes. All data in the zipped archives can be used with the SEISAN seismology software.
