| dc.description | We perform microtremors measurements at Concepción and compute the predominantfrequency using horizontal-to-vertical spectral ratio (HVSR). We compare these results with the surface geology and several geotechnical surveys existing in the region, enabling a general characterization of the area. We present and complement these results with observations of damage produced by the Mw 8.8 Maule 2010 earthquake. Preliminary results show the presence of fine-grained materials in the area characterized by very low predominant frequency (lower than 1.5 Hz), which might explain the extensive damage observed at Concepción and surroundings. | |
