Abstract

This study analyses the performance of residential buildings in the town of Hveragerði in South Iceland during the 29 May 2008 Mw 63 Ölfus Earthquake The earthquake occurred very close to the town approximately 3–4 km from it Ground shaking caused by the earthquake was recorded by a dense strongmotion array in the town The array provided highquality threecomponent ground acceleration data which is used to quantify a hazard scenario In addition surveys conducted in the town in the aftermath of the earthquake have provided information on macroseismic intensity at various locations in the town Detailed information regarding the building stock in the town is collected and their seismic vulnerability models are created by using building damage data obtained from the June 2000 South Iceland earthquakes Damage to buildings are then simulated by using the scenario hazard and vulnerability models Damage estimates were also obtained by conducting a survey Simulated damage based on the scenario macroseismic intensity is found to be similar to damage estimated from survey data The buildings performed very well during the earthquake—damage suffered was only 5  of the insured value on the average Correlation between actual damage and recorded groundmotion parameters is found to be statistically insignificant No significant correlation of damage was observed even with macroseismic intensity Whereas significant correlation was observed between peak ground velocity and macroseismic intensity neither of them appear to be good indicators of damage to buildings in the study area This lack of correlation is partly due to good seismic capacity of buildings and partly due to the ordinal nature of macroseismic intensity scale Consistent with experience from many past earthquakes the survey results indicate that seismic risk in South Iceland is not so much due to collapse of buildings but rather due to damage to nonstructural components and building contentsThis study was cofinanced by the EU Civil Protection Financial Instrument under the Urban disaster Prevention STRATegies using MAcroseismic fields and FAult sources UPSTRATMAFA project grant agreement number 23031/2011/613486/SUB/A5 Partial funding was provided by the University of Iceland research fund
