SPATIAL DISTRIBUTION OF PIPELINE DAMAGE IN DüZCECAUSED BY THE 1999 KOCAELI AND DüZCE EARTHQUAKES

摘要

Results are presented of an investigation into water pipeline damage in Düzce, Turkey, following the 1999Kocaeli and Düzce earthquakes. Temporal variations in pipeline repairs are analysed to identifyearthquake-related pipe breaks. GIS-based analysis reveals no clear correlations between spatialdistributions of pipeline damage and site conditions, as characterised by microtremor measurements. Areasonable correlation is observed between pipeline damage and building damage. The spatialdistribution of peak ground velocity during the Kocaeli earthquake is approximated using pipeline damagedata. Interpretation of pipeline damage caused by the Düzce earthquake is obscured by the effects of theearlier Kocaeli earthquake.
