A GIS-based approach for earthquake loss estimation

What is it about?

Rapid relief operation after relatively strong earthquakes leads to casualty numbers reduction. The determination of damaged areas and the casualties’ estimation immediately after an earthquake event are regarded as two key elements in the management of relief operations. . In this study, a loss estimation method is proposed by combining data from remote sensing technology and geographic information system (GIS).

Why is it important?

Previous methods may be acceptable predictors of earthquake effects for a block of buildings. They are, however, not accurate predictors for a specific building. Building-specific estimation is definitely more accurate and reliable than the above-mentioned methods if it is used for an area because it is based on the properties of a particular building.
