PSPicker is a matlab tool that performs automatic picking of first arrivals on seismic traces. The code is written to take MSEED files as an input but the main function can take a simple matlab array. The method used is detailed in Baillard et al., 2014. Feel free to contact me if you need some help to apply the picker to your own dataset ;)
The seismic catalog from the 2008-2009 ARCVANUATU project. The directory contains also a STATION0.HYP file where you can find the station coordinates and the velocity model used to locate the earthquakes.
