Drought left 225 million trees dead in the U.S. Southwest in 2002. Nine years later, it killed 300 million trees in Texas. This past year, 12 million trees died in California.Drought left 225 million ...
Hanging on the line–on the need to assess the risk to global submarine telecommunications infrastructure–an example of the Hawaiian bottleneck and Australia
global submarine telecommunications infrastructure Hawaiian bottleneck Australia

National economies are becoming increasingly dependent on the global telecommunications system – and in particular, its submarine cable infrastructure. We note that a variety of natural hazard process...
Mitigating mountain hazards in Austria–legislation,risk transfer,and awareness building
Mitigating mountain hazards legislation risk transfer awareness building
2009/12/16
Embedded in the overall concept of integral risk management, mitigating mountain hazards is pillared by land use regulations, risk transfer, and information. In this paper aspects on legislation relat...
We analytically estimate the risk function of natural hazards (earthquakes, rockfalls, forestfires, landslides) by means of a non-extensive approach which is based on implementing the Tsallis entropy ...
Improving risk assessment by defining consistent and reliable system scenarios
risk assessment consistent and reliable system scenarios
2009/12/16
During the entire procedure of risk assessment for hydrologic hazards, the selection of consistent and reliable scenarios, constructed in a strictly systematic way, is fundamental for the quality and ...
Taking the heterogeneity of citizens into account:flood risk communication in coastal cities–a case study of Bremen
heterogeneity of citizens flood risk communication coastal cities
2009/12/10
The likely manifestations of climate change like flood hazards are prominent topics in public communication. This can be shown by media analysis and questionnaire data. However, in the case of flood r...
Integrated urban flood risk assessment–adapting a multicriteria approach to a city

Rock slides and rock falls are the most frequent types of slope movements in Yosemite National Park, California. In historical time (1857–2002) 392 rock falls and rock slides have been documented in t...
Tsunami risk assessment in the Marquesas Islands (French Polynesia) through numerical modeling of generic far-field events
Islands (French Polynesia) numerical modeling generic far-field events

We present in this paper the simulations carried out to study potentially threatening areas located at the Pacific Rim, on the seismogenic Aleutian and Tonga subduction zones. We use a constant seismi...
Risk-based stabilization planning for soil cut slopes
Risk-based stabilization planning soil cut slopes
2009/12/8
Risk-based slope stabilization planning integrates the failure probability and the failure consequence systematically and shows promise for use in the practice. This paper attempts to develop a risk-b...
The use of questionnaires for acquiring information on public perception of natural hazards and risk mitigation–a review of current knowledge and practice
acquiring information public perception natural hazards risk mitigation
2009/12/8
Questionnaires are popular and fundamental tools for acquiring information on public knowledge and perception of natural hazards. Questionnaires can provide valuable information to emergency managemen...
Coupled modelling of subsurface water flux for an integrated flood risk management
Coupled modelling subsurface water flux integrated flood risk management
2009/12/8
Flood events cause significant damage not only on the surface but also underground. Infiltration of surface water into soil, flooding through the urban sewer system and, in consequence, rising groundw...
Assessing global exposure and vulnerability towards natural hazards:the Disaster Risk Index
global exposure vulnerability natural hazards Disaster Risk Index
2009/12/8
This paper presents a model of factors influencing levels of human losses from natural hazards at the global scale, for the period 1980–2000. This model was designed for the United Nations Development...
