000020015 520__ $$2eng$$aThe Chilean Seismological Networks has been rapidly growing these past years, going from few dozens of stations, to nearly a 100 installed all over the country. Even more, this network is complemented by the Accelerographic National Network, with nearly 300 strong-motion stations, deployed on a large effort by the National Office of Emergencies (Onemi), in a variety of cities and site conditions all over the country. All of these stations are currently providing very useful information of the earthquakes that take place in Chile, and are expected to record moderate to large events. However, the lack of appropriate site characterization sets an important limit to its usefulness. In the present work, we propose a methodology to begin a geophysical characterization of all of these stations, based on array measurements of microtremors and horizontal-to-vertical spectral ratios. In the present work, we present some preliminary results for some stations located in Valparaíso, Coquimbo, Tarapacá, and the Metropolitan regions. This information will help improve our understanding of the behavior of soils during an earthquake, providing relevant information for seismic codes.
