Abstract
Domain ontology, encompassing both concepts and instances, along with their relations and properties, is a new medium for the storage and propagation of domain specific knowledge. A significant problem remains the effort which must be expended during ontology construction. This involves collecting the domain-related vocabularies, developing the domain concept hierarchy, and defining the properties of each concept and the relationships between concepts. Recently several engineering handbooks have described detailed domain knowledge by organizing the knowledge into categories, sections, and chapters with indices in the appendix. This paper proposes the extraction of concepts, instances, and relationships from a handbook of a specific domain to quickly construct base domain ontology as a good starting point for expediting the development process of more comprehensive domain ontology. The extracted information can also be reorganized and converted into web ontology language format to represent the base domain ontology. The generation of a base domain ontology from an Earthquake Engineering Handbook is used to illustrate the proposed approach. In addition, quality evaluation of the extracted base ontology is performed and discussed. (C) 2010 Elsevier Ltd. All rights reserved.

Abstract
Determining the most effective public warnings to issue during a hazardous environmental event is a complex problem. Three primary questions need to be answered: Who should take protective action? What is the best action? and When should this action be initiated? Warning triggers provide a proactive means for emergency managers to simultaneously answer these questions by recommending that a target group take a specified protective action if a preset environmental trigger condition occurs (e.g., warn a community to evacuate if a wildfire crosses a proximal ridgeline). Triggers are used to warn the public across a wide variety of environmental hazards, and an improved understanding of their nature and role promises to: (1) advance protective action theory by unifying the natural, built, and social themes in hazards research into one framework, (2) reveal important information about emergency managers' risk perception, situational awareness, and threat assessment regarding threat behavior and public response, and (3) advance spatiotemporal models for representing the geography and timing of disaster warning and response (i.e., a coupled natural-built-social system). We provide an overview and research agenda designed to advance our understanding and modeling of warning triggers.

Abstract
Household evacuation preparation time distributions are essential when computing evacuation time estimates (ETEs) for hurricanes with late intensification or late changing tracks. Although evacuation preparation times have been assessed by expected task completion times, actual task completion times, and departure delays, it is unknown if these methods produce similar results. Consequently, this study compares data from one survey assessing expected task completion times, three surveys assessing actual task completion times, and three surveys assessing departure delays after receiving a warning. In addition, this study seeks to identify variables that predict household evacuation preparation times. These analyses show that the three methods of assessing evacuation preparation times produce results that are somewhat different, but the differences have plausible explanations. Household evacuation preparation times are poorly predicted by demographic variables, but are better predicted by variables that predict evacuation decisions-perceived storm characteristics, expected personal impacts, and evacuation facilitators.

Our Washington Pacific Coast is vulnerable to tsunami waves. These waves will wash over coastal communities that do not have ready access to high ground. The Institute for Hazards Mitigation Planning and Research has been working with these at-risk communities at the direction or the State Emergency Management Division to identify locations for vertical tsunami refuges. Currently, the Institute is applying an evacuation model developed by the USGS to corroborated locations suggested by residents. These suggested locations were the product of Institute research conduct over the past 8 years and which lead to the construction of structures in Tokeland and Westport, Washington.
Michael K. Lindell has conducted research on emergency preparedness and response for a wide range of natural and technological hazards over the past 40 years. He has conducted research or provided technical services to 40 different organizations in the public and private sectors. He has provided technical assistance on radiological emergency preparedness for the International Atomic Energy Agency, the US Nuclear Regulatory Commission, the Department of Energy, and nuclear utilities and also worked on hazardous materials emergency preparedness with State Emergency Response Commissions, Local Emergency Planning Committees, and chemical companies. He has served eight times as a consultant to National Research Council committees examining environmental hazards, and has been a member of three National Research Council committees—Disasters Research in Social Sciences, Assessing Vulnerabilities Related to the Nation’s Chemical Infrastructure, and Inherently Safer Chemical Processes: The Use of Methyl Isocyanate (MIC) at Bayer CropScience. In addition, he has reviewed research proposals for 20 different foreign, federal, and state agencies as well as performed manuscript reviews for over 75 different journals in the social and environmental sciences and engineering. He has written extensively on emergency management and is the author of 80 technical reports, 125 journal articles and book chapters, and nine books.
The Institute for Hazards Mitigation Planning and Research is an interdisciplinary academic institute housed in the College of Built Environments. The Institute is dedicated to exploring ways to enhance Community Resilience, through integration of hazards mitigation principles across all aspects of community development. Its mission is to build a resource center that will enhance risk reduction and resilience activities through research and analysis of hazards, policies related to mitigation, and outreach to the community.
The Institute for Hazards Mitigation Planning and Research is dedicated to integrating hazards mitigation principles into a wide range of crisis, disaster, and risk management opportunities. The Institute provides expertise in disaster preparedness, response, and recovery with a special emphasis on mitigation and planning in the promotion of community sustainability. It is interdisciplinary in focus and structure, and the capabilities of the Institute are enhanced by its close relationship with other academic and research organizations. This incorporates collaboration with several other disciplines within the University of Washington.
The Institute’s faculty and researchers are involved in numerous innovative and path-breaking research initiatives with the ultimate goal of enhancing community capacity to anticipate, respond to, cope with, and recover from natural and man-made hazard events.
