This abstract demonstrates joint use of P- and S-waves with a surface monitoring network. Using the best quality microseismic events from a dataset recorded with three components sensors; we first estimated an optimal velocity model through simulated annealing. We subsequently used it to detect and locate smaller events in a relative way. Our results show that the location - while using only P–waves - is poorly constrained and adding an S phase gives a significant improvement.
