COMPARISON OF OBSERVED DAMAGE WITH RESULTS FROM ANALYTICAL SIMULATION MODELS. THE CASE OF JULY 9, 1998, FAIAL EARTHQUAKE IN THE AZORES.
The July 9, 1998 earthquake that struck Faial, Pico and S?o Jorge Islands in the Azores archipelago provided a large amount of information which permits the validation of damage scenarios simulators. Ten years later and integrated on the project FCT-POCI/CTE-GIN/58095/2004 USuET -Urban System under Earthquake Threat, we are able to recreate earthquake effects in the urban areas that comprise about 3000 buildings using data collected during the reconstruction period (1998-2007). Based on a post-inspection of building files, a database was compiled with typology classification, damage description, reconstruction techniques and costs of intervention.For this stock of housing we developed a damage scenario simulator using the empirical vulnerability methods of the EMS-98 macroseismic scale as well as vulnerability obtained through mechanical modelling of a few typologies. The influence of the soil layers (geological and geomorphologic effects) were also taken into account as part of the attenuation process.The aim of present article is to compare values, in terms of number of collapsed houses and mean damage grade obtained by the seismic simulator with those verified on July 9, 1998, and update the analytical models in order to reduce the error between model results and observed values.
