Abstract:
The Chilean National Seismological Centre (CSN), have been installed and operated, from 2013, a large GNSS network, including Pacific island and Antarctic region, with more of 130 stations. We have implemented a schedule of processing in two different approaches: on one hand, we have a daily solution, which are stacking and combined to recover inter-seismic strain accumulation, seasonal and local variation, for seismic cycle observation; these solutions are made using rapid and definitive IGS products (15 hours to 15 days). On the other hand, we have implemented a real time solution for rapid earthquake characterization, with 1-Hz streams, that enable us to recover the geometry of the rupture area, assess the maximum displacements, and W-phase analysis. We will show results from all of these solutions.
