Text S1: Locating seismicity in the Eastern Sierras Pampeanas
Analyzing 40-sps data recorded by the ESP array from 2008 August to 2009 August, we characterize the amount, distribution and style of seismicity within this region by calculating both single- and multiple-event earthquake locations. Details in this supplement describe the location methods used, the parameters tested and the factors contributing to uncertainties in the earthquake hypocentres.
Figure S1. Seismicity maps comparing the hypocentre of events calculated using different parameters. Blue dots indicate the hypocentres from the first set of specified parameters and red dots indicate the hypocentres from the second set.
Figure S2. A map view and cross-sectional comparison between hypocentres calculated by (A) Antelope and (B) HypoDD with the IASP91 velocity model.
Figure S3. Graph plotting the traveltime of P waves against the distance from each event to the recording station based on the single-event locations.
Figure S4. Velocity models used in the single- and multiple-event location methods.
Figure S5. All FOCMEC solutions calculated for each event presented in this study. Great circles indicate the locations of all fault and nodal planes allowed by FOCMEC.
Table S1. The relationship between delta time values for picks from Antelope and the weighting value given in HypoDD for the weighting scheme based on pick confidence.
Table S2. Input parameters for calculating the focal mechanism solutions for each event as indicated by ORID number. ESP stations are listed on the left.
Table S3. Details of the focal mechanism solutions, the hypocentres of the events and the HypoDD residual for the hypocentres.
Table S4. Single-event and multiple-event locations of all the earthquakes located using data from the ESP array between August 2008 and August 2009, including the origin identification number (ORID), latitude (LAT), longitude (LON), depth (DEP), date, time and sdobs or rms.
