| Zusammenfassung |
| The use of Very High Resolution (VHR) satellite panchromatic image is
nowadays an effective tool to detect and investigate surface effects of
natural disasters. We specifically examined the capabilities of VHR images to
analyse earthquake features and detect changes based on the combination of
visual inspection and automatic classification tools. In particular, we have
used Quickbird (0.6 m spatial resolution) images for detecting the three
main co-seismic surface features: damages, ruptures and landslides. The
present approach has been applied to the 8 October 2005, Mw7.6
Kashmir, Pakistan, earthquake. We have focused our study in and around the
main urban areas hit by the above earthquake specifically at Muzaffarabad and
Balakot towns. The automatic classification techniques provided the best
results wherever dealing with the damage to man-made structures and
landslides. On the other hand, the visual inspection method demonstrated in
addressing the identification of rupture traces and associated features. The
synoptic view (concerning landslide, more than 190 millions of pixels have
been automatically classified), the spatiotemporal sampling and the fast
automatic damage detection using satellite images provided a reliable
contribution to the prompt response during natural disaster and for the
evaluation of seismic hazard as well. |
