| Zusammenfassung |
| Typhoon Morakot caused terrible flooding and torrential rains that severely
damaged southern Taiwan. Swollen rivers wiped out roads and demolished
buildings. Long-lasting and intense rainfall triggered landslides in many
regions in southern Taiwan, including the landslide that buried Siaolin
Village in Kaohsiung County and killed approximately 500 people. Locating
buried buildings immediately after a landslide could be an emergent issue in
life saving and hazard mitigation. Analyzing the magnetic signature of a
buried area is an efficient and non-destructive way to detect subsurface
buildings. This paper presents the results of a magnetic survey for the
purpose of outlining subsurface images of Siaolin Village after the
catastrophic landslide induced by Typhoon Morakot in 2009. We found that a
high-resolution magnetic survey can reveal suspected building positions that
match the initial locations of buildings in Siaolin Village. The estimated
depths of the buried buildings are 5–10 m deep. The magnetic data further
suggest a possible debris-flow direction of NE to SW because the northern
part of the village was mostly destroyed, while buildings in the southern
part of the village remained in place. |
