El terremoto chileno del 27 de febrero de 2010: análisis preliminar de las consecuencias en la ciudad de Valdivia

The chilean earthquake of february 27, 2010: Preliminary analysis of its consequencesin the city of Valdivia The main seism affecting the city of Valdivia after the famous earthquake of 1960 was the event (Mw=8.8) which occurred on February 27, 2010 in central Chile. It has been assigned an intensity of Mercalli VI for the city of Valdivia. In order to understand the spatial distribution of the damage caused to urban infrastructure, the latter was related to the local soil conditions. Backgrounds of both the seismic history and the city development provide valuable information which was added to the analysis. The dissimilar severity the seism had on the different quarters of Valdivia is closely associated with the geomorphological units and the foundation soil types which are present in the city. A good coincidence with the seismic response of the soils foreseen for the city in previous studies could be established.
