Estimating waste induced by earthquakes within damage scenarios
Résumé
The objective of this work was to find and test tools to estimate waste tonnage caused by earthquakes. These estimations can be useful for prevention actions like exercises or waste plans but also during the seismic crisis management. Three different methods have been tested using building damage scenarios done in Nice city (Southern France): Hirayama method which is based on Japan experience and Japanese building stock, MECADEPI-HAZUS method which is a hybrid method based on works done in France about floods wastes and HAZUS methodology used in the USA and finally a method based on L’Aquila experience in Italy. Even if needed input data is quite different for the three methods, results using these methods tends to the same order of magnitude on inert rush. Finally the work compares potential waste tonnage caused by seismic scenarios with local/regional annual waste storage and treatment capacities, as a measure of the waste overflow.
