Even more, nearly 300 strong‐motion stations from the Accelerographic National Network have recently complemented this network, mainly deployed in large cities, at a variety of site conditions. All of these stations are currently providing useful information of Chilean earthquakes and are expected to record moderate‐to‐large events. However, the lack of appropriate site characterization sets an important limit to its usefulness. In this work, we present the geophysical characterization of 163 stations, the first results of larger effort to complete the characterization at all sites, based on array measurements of microtremors and horizontal‐to‐vertical spectral ratios. This information will help improve our understanding of the dynamic behavior of soils during earthquakes, providing relevant information for seismic design and seismic codes.
