| Zusammenfassung |
| An accurate estimation of a casualty rate is critical in response to
earthquake disasters, and could allow an increase in the survival rate.
Building damage is considered to be a major cause of earthquake casualties in
developing countries. High-resolution satellite imagery (HRSI) can be used to
detect the building damage in a period of a short time. This makes it
possible to use a model to estimate earthquake casualties immediately after
the occurrence of an earthquake. With respect to the capability of HRSI, this
study built a new model for estimating the casualty rate in an earthquake
disaster based on remote sensing and a geographical information system. Three
groups of earthquake data, the 2003 Bam earthquake, the 2008 Wenchuan
earthquake, and the 2010 Yushu earthquake, were used to evaluate this model.
The results indicated that our new model significantly improved the accuracy
in predicting the casualty rate. The parameters used in the model vary
between developed and developing countries. This study could provide valuable
information for a more efficient rescue operation in response to earthquakes. |
