The prehistoric Bangudae Petroglyph in the Ulsan area represents an outstanding National Treasure of the Republic of Korea. Since the construction of the Sayeon dam, the petroglyph with about two hundred carvings is periodically submerged by the Sayeon reservoir. The danger of increasing damage has resulted in intensive efforts to protect this cultural heritage. Diagnosis and risk prognosis studies were carried out. Results of petrographical studies, monument mapping and in situ measurements are presented. Types, degree and zonation of damage are evaluated. The risk estimation derived from the studies confirms the necessity of preservation measures. 相似文献

An integrated framework for disaster risk management is presented to cope with the risk of low-probability high-consequence
(LPHC) disasters in urban communities. Since the 2000 Tokai flood in Japan, there has been a shift in the management strategy
from disaster prevention with a presumed zero risk to disaster reduction with an acceptable risk. The framework consists of:
(i) integration of a different categories of risk reduction options in terms of structural and nonstructural measures, regulation
and market-oriented measures, (ii) strengthening of the capacity of local communities to make their own management choices
for LPHC-type disaster risks, and (iii) promoting the participation of stakeholders throughout the entire cycle of risk management.
The interdisciplinary framework is discussed with reference to lessons learned from two recent major flood disasters (the
2000 Tokai flood and the 2004 Niigata flood). To implement the goals of the integrated framework, a participatory platform
for disaster risk communication called “Pafrics” has been developed. Preliminary results of the pilot study of participation
and risk communication supported by Pafrics are presented. 相似文献

Almost annually, natural hazards such as floods and landslides cause a great deal of financial loss and human suffering in
Taiwan. In order to gain a better understanding of disaster preparedness, this paper examines several factors in relation
to hazard mitigation behavior: social economic status (education, income), psychological vulnerability (sense of powerless
and helpless), risk perception (perceived impact and control) and social trust. The statistical analysis reported here is
based on the “2004 National Risk Perception Survey of Floods and Landslides in Taiwan”. The main findings include: (1) in
comparison with general public, victims are less willing to adopt risk mitigation measures than the public, even though they
perceive larger impacts, worry more about the hazard, and pay more attention to hazard information; (2) trust, risk perception
and social economic status are positive predictors for mitigation intentions, whereas psychological vulnerability is a negative
predictor; and (3) psychological variables are stronger predictors for mitigation intentions than that of socio-economic variables.
In light of these findings, the policy implications and intervention strategy are also discussed.

Drought risk assessment in the western part of Bangladesh 总被引:14,自引:8,他引:6
Though drought is a recurrent phenomenon in Bangladesh, very little attention has been so far paid to the mitigation and preparedness
of droughts. This article presents a method for spatial assessment of drought risk in Bangladesh. A conceptual framework,
which emphasizes the combined role of hazard and vulnerability in defining risk, is used for the study. Standardized precipitation
index method in a GIS environment is used to map the spatial extents of drought hazards in different time steps. The key social
and physical factors that define drought vulnerability in the context of Bangladesh are identified and corresponding thematic
maps in district level are prepared. Composite drought vulnerability map is developed through the integration of those thematic
maps. The risk is computed as the product of the hazard and vulnerability. The result shows that droughts pose highest risk
to the northern and northwestern districts of Bangladesh. 相似文献

This article describes a methodology to analyse debris-flow risk in the torrential watersheds of the southern hillside of
Gargano (Puglia—Italy). The approach integrates a stability model that identifies the areas of potential shallow landslides
in different meteorological conditions with a two-dimensional flood routing model that allows hazard mapping and GIS interface.
The results were combined with a susceptibility map that was defined by analyzing the vulnerability conditions and the exposure
of the alluvial fan. The models were calibrated on the 1972, July catastrophic event for which the distribution of rainstorm
intensity was available. The geo-mechanical properties of the debris were studied by field surveys and laboratory tests while
the sediment source areas and the shape of the alluvial cone were obtained using photo-aerial interpretation. The risk conditions
of the areas under consideration were also investigated in order to plan and guide measures aimed at limiting the damage such
hazards may cause. 相似文献

Post-Bam earthquake: recovery and reconstruction 总被引:3,自引:1,他引:2
This paper gives a brief explanation of the earthquake in Bam. It also reports on the rescue and relief operations, including
the construction of emergency shelters and temporary housing, and on the country’s plan for the reconstruction of the city,
which includes debris removal, the rebuilding of rural and urban residential and commercial units, the reconstruction of state
and public buildings and public facilities such as schools, rural and urban water aqueducts and grids, the construction of
a sewage system, power network and telecommunication system, the provision of water to orchards and farmlands, the renovation
of industries and the revival of the cultural heritage, particularly the historical Bam citadel, among others. We also report
briefly on the effect of the Bam earthquake on the Iran Earthquake Risk Reduction Strategy and actions.
