Collective action for community-based hazard mitigation: a case study of Tulsa project impact

Lee, Hee Min 01 November 2005 (has links)
During the past two decades, community-based hazard mitigation (CBHM) has been newly proposed and implemented as an alternative conceptual model for emergency management to deal with disasters comprehensively in order to curtail skyrocketing disaster losses. Local community members have been growingly required to share information and responsibilities for reducing community vulnerabilities to natural and technological hazards and building a safer community. Consequently they are encouraged to join local mitigation programs and volunteer for collective mitigation action, but their contributions vary. This research examined factors associated with Tulsa Project Impact partners?? contributions to collective mitigation action. In the literature review, self-interest and social norms were identified and briefly discussed as two determinants to guide partners?? behavior by reviewing game theoretic frameworks and individual decision-making models. Partners?? collective interest in building a safer community and feelings of obligation to participate in collective mitigation action were also considered for this study. Thus, the major factors considered are: (1) collective interests, (2) selective benefits, (3) participation costs, (4) norms of cooperation, and (5) internalized norms of participation. Research findings showed that selective benefits and internalized norms of participation were the two best predictors for partners?? contributions to collective mitigation action. However, collective interests, participation costs, and norms of cooperation did not significantly influence partners?? contributions.

Designing for disasters : incorporating hazard mitigation methods into the LEED for new construction and major renovations framework

Gray, Meredith Eileen, 1984- 24 November 2010 (has links)
Green buildings are increasingly in demand yet current green building practices often do not consider hazard mitigation. High-performance buildings that can withstand hazards, protect residents, and do not need to be rebuilt following a disaster are truly sustainable buildings. This report focuses on current hazard mitigation and disaster resilience standards for wildfires and earthquakes through an in-depth analysis of case studies and best practices for these hazards. The U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) framework is the ideal vehicle to incorporate hazard mitigation methods into official green building certification. Language for a new LEED Hazard Mitigation and Resilience credit area is established using guidelines for hazard mitigation for wildfires and earthquakes. / text

Magma plumbing architecture in Indonesia and the North Atlantic Igneous Province

Dahrén, Börje January 2016 (has links)
Magma plumbing systems represent the physical framework of magma transport and storage from the source region in the mantle, through the crust, until reaching the surface in a volcanic eruption. Characterising the different aspects of magma plumbing, in particular the distribution of magma storage zones throughout the crust, is of key importance to better understand the behaviour of individual volcanoes. In particular, shallow crustal magma storage and associated magma-crust interaction processes could potentially explain some of the worlds most unpredictable and explosive volcanoes. This thesis studies magma plumbing architecture in the Sunda Arc (Indonesia), and the North Atlantic Igneous Province, based on elemental and isotope geochemistry, and derived petrological modelling. In this study, I have employed petrological models, so called geothermobarometers, to calculate pressures and temperatures (P-T) of crustal magma storage. Geothermobarometers are calibrated thermodynamic formulations based on the composition of magmatic minerals and their co-existing melt as a function of the P-T conditions of crystallisation. Using the calculated P-T estimates, I was able to derive the depth of magma storage, and thereby reconstruct the architecture of magma storage systems. A number of different geothermobarometers based on different mineral phases, including plagioclase, clinopyroxene and olivine, were used for this purpose, The geothermobarometric modelling was combined with additional elemental and isotope geochemical analyses, as well as collaborations with geophysical investigations. These additional approaches were used to corroborate the findings of the geothermobarometric modelling, and also to model and quantify magma-crust interaction processes that take place during crustal magma storage, such as assimilation of crustal lithologies into the magmatic system. The findings of this thesis build upon the growing body of evidence in support of the prevalence of shallow magma storage in different volcanic settings worldwide. This realisation is relevant to volcano monitoring and hazard mitigation worldwide.

Santa Barbara Tea Fire Multi-Hazard Mitigation Benefit Cost Analysis

Flamm, David S 01 June 2009 (has links)
ABSTRACT Santa Barbara Tea Fire Multi-Hazard Mitigation Benefit Cost Analysis David S Flamm This study examines the benefits and costs associated with the outright purchase of properties for hazard mitigation (“property acquisition mitigation”) in Santa Barbara, California which reduced four properties’ exposure to multiple hazards. The results indicate that the estimated overall benefit-cost ratio for property acquisition mitigation projects is 1.75:1 when the exposed properties meet a threshold of eminent threat for total loss. This study further suggests that when property acquisitions are performed in an area threatened by multiple hazards the mitigation becomes two to three times more beneficial than in an area threatened by a single hazard. Possible implications and future benefits associated with this mitigation and mitigations like this are also explored. Multi-hazard mitigation is an action taken to reduce or eliminate long-term risks from natural or human-caused hazards. A hazard is any condition or event with the potential to cause fatalities, injuries, property damage, infrastructure damage, economic interruptions, environmental damage, or other loss. The study area for the Tea Fire BCA (Benefit Cost Analysis) is subject to multiple hazards, primarily landslides, wildfires, and earthquakes. In an attempt to reduce the exposure to landslides a mitigation project was completed in 1998. This project included purchase of four properties by the City of Santa Barbara using federal and local funds. The undeveloped properties were left empty as open space to eliminate the exposure to risk. The project, originally intended to mitigate landslide risk, mitigated risk exposure to multiple hazards. The mitigation was put to the test during the Santa Barbara Tea Fire, a wildfire which burned approximately 2,000 acres of Santa Barbara County land in November, 2008. The following steps were followed to determine the overall loss avoidance: 1. Obtain building values before mitigation 2. Obtain current comparable building values 3. Determine burn recurrence in study area 4. Obtain fire damage estimates from FEMA BCA tool based on “before mitigation” building and contents values 5. Calculate “loss avoidance” and adjust for inflation using FEMA BCA tool 6. Add additional avoided losses not considered in BCA (e.g., emergency management costs) 7. Subtract new losses resulting from the project 8. Determine multi-hazard recurrence in study area Keywords: Hazard Mitigation, Benefit Cost Analysis, Loss Avoidance.

Modification of the Priority Risk Index: Adapting to Emergency Management Accreditation Program Standards for Institutes of Higher Learning Hazard Mitigation Plans

Harris, Joseph B., Bartlett, Geoffrey, Joyner, T. A., Hart, Matthew, Tollefson, William 01 March 2021 (has links)
The Priority Risk Index is increasingly used as a methodology for quantifying jurisdictional risk for hazard mitigation planning purposes, and it can evolve to meet specific community needs. The index incorporates probability, impact, spatial extent, warning time, and duration when assessing each hazard, but it does not explicitly integrate a vulnerability and consequence analysis into its final scoring. To address this gap, a new index was developed- the Enhanced Priority Risk Index (EPRI). The new index adds a sixth category, vulnerability, calculated from a vulnerability and consequence analysis of the impacts on seven sectors identified in Standard 4.1.2 of the Emergency Management Accreditation Program (EMAP). To obtain a vulnerability score, impacts are ranked by sector from low (1) to very high (4), then a weighting factor is applied to each sector. The vulnerability score is added to the EPRI and provides risk levels based on the number of exploitable weaknesses and countermeasures identified within a specific jurisdiction. The vulnerability score and resulting EPRI are scalable and can be applied across jurisdictions, providing a transferable methodology that improves the hazard identification and risk assessment process and provides an approach for meeting EMAP accreditation standards.

Quantifying the Greenhouse Gas Emissions of Hazards: Incorporating Disaster Mitigation Strategies in Climate Action Plans

Germeraad, Michael 01 March 2014 (has links) (PDF)
Reconstruction after natural disasters can represent large peaks in a community’s greenhouse gas emission inventory. Components of the built environment destroyed by natural hazards have their useful life shortened, requiring replacement before functionally necessary. Though the hazard itself does not release greenhouse gasses, the demolition and rebuilding process does, and these are the emissions we can quantify to better understand the climate impacts of disasters. The proposed methodology draws data from existing emission and hazard resource literature and combines the information in a community scale life cycle assessment. Case studies of past disasters are used to refine the methodology and quantify the emissions of single events. The methodology is then annualized projecting the emissions of future hazards. The annualization of greenhouse gasses caused by hazard events provides a baseline from which reduction strategies can be measured against. Hazard mitigation strategies can then be quantified as greenhouse gas reduction strategies for use in Climate Action Plans. The methodology combines the fields of climate action, hazard mitigation, and climate adaptation. Each field attempts to create sustainable and resilient communities, but most plans silo each discipline, missing opportunities that are mutually beneficial. Quantifying the greenhouse gasses associated with recovery following a disaster blends these fields to allow development of comprehensive resilience and sustainability strategies that lower greenhouse gases and decrease risk from existing or projected hazards.

The Privatization of Hazard Mitigation: A Case Study of the Creation and Implementation of a Federal Program

Jerolleman, Alessandra 06 August 2013 (has links)
This dissertation explores the role of the private and public sectors in hazard mitigation, an important part of the Federal Emergency Management Agency’s (FEMA’s) performance requirements from the Stafford Act. Hazard mitigation is the effort to reduce societal impacts from natural disasters by reducing their risk to people, property and infrastructure; before hazards occur. The goal of the work is to contribute to the literature examining the national trend towards privatization and reliance on the free market economy for the provision of government social services, through such public management movements as the “New Public Management” (NPM) of the 1980s and the general efficiency movement that encompasses a greater market orientation in public government and an increase in the use of private sector contractors as an alternative to public provision (Boston 1996). The primary question which this dissertation seeks to answer is: How has the provision of hazard mitigation services by the private sector come to be the norm and what have been the consequences. Due to the broad nature of the question and the lack of previous research, this dissertation will utilize a mixed methods approach with the goal of gaining a broad understanding of the privatization of the hazard mitigation sector in its various manifestations. The approach consists of one case study, broken down into two time periods: hazard mitigation prior to the passage of the Disaster Mitigation Act of 2000, and hazard mitigation following the Disaster Mitigation Act of 2000. The case study is based primarily upon a series of interviews and includes several imbedded cases. They will be contextualized within an overall description of hazard mitigation focusing on the history and the context of the relevant federal legislation.

A Risk-based Optimization Modeling Framework for Mitigating Fire Events for Water and Fire Response Infrastructures

Kanta, Lufthansa Rahman 2009 December 1900 (has links)
The purpose of this dissertation is to address risk and consequences of and effective mitigation strategies for urban fire events involving two critical infrastructures- water distribution and emergency services. Water systems have been identified as one of the United States' critical infrastructures and are vulnerable to various threats caused by natural disasters or malevolent actions. The primary goals of urban water distribution systems are reliable delivery of water during normal and emergency conditions (such as fires), ensuring this water is of acceptable quality, and accomplishing these tasks in a cost-effective manner. Due to interdependency of water systems with other critical infrastructures-e.g., energy, public health, and emergency services (including fire response)- water systems planning and management offers numerous challenges to water utilities and affiliated decision makers. The dissertation is divided into three major sections, each of which presents and demonstrates a methodological innovation applied to the above problem. First, a risk based dynamic programming modeling approach is developed to identify the critical components of a water distribution system during fire events under three failure scenarios: (1) accidental failure due to soil-pipe interaction, (2) accidental failure due to a seismic activity, and (3) intentional failure or malevolent attack. Second, a novel evolutionary computation based multi-objective optimization technique, Non-dominated Sorting Evolution Strategy (NSES), is developed for systematic generation of optimal mitigation strategies for urban fire events for water distribution systems with three competing objectives: (1) minimizing fire damages, (2) minimizing water quality deficiencies, and (3) minimizing the cost of mitigation. Third, a stochastic modeling approach is developed to assess urban fire risk for the coupled water distribution and fire response systems that includes probabilistic expressions for building ignition, WDS failure, and wind direction. Urban fire consequences are evaluated in terms of number of people displaced and cost of property damage. To reduce the assessed urban fire risk, the NSES multi-objective approach is utilized to generate Pareto-optimal solutions that express the tradeoff relationship between risk reduction, mitigation cost, and water quality objectives. The new methodologies are demonstrated through successful application to a realistic case study in water systems planning and management.
