Abstract: A rapid, holistic view of earthquake disasters begins with earthquake location and magnitude, alerted by seismic networks. The initial source characteristics, along with any available ground-shaking observations, can be used to rapidly estimate the shaking extent, its severity (e.g., ShakeMap), and its likely impact to society, for example, employing the U.S. Geological Survey's Prompt Assessment of Global Earthquakes for Response, or PAGER, system. When serous impacts are likely, PAGER's impact-based alerts can, in turn, begin the process of primary response at the local, national, or international level, and the process of reconnaissance via social media, the mainstream media, scientific analyses, and remotely-sensed and ground-truth observations. In this work-in-progress report, we describe our initial efforts to incorporate event-specific ground-truth observations and model secondary ground-failure hazards back into the loss-modeling domain in order to provide a more holistic view each earthquake disaster.

Abstract: Social media allows the public to engage in the disaster response and recovery process in new and exciting ways. Many emergency management agencies in the United States are embracing social media as a new channel for alerts, warnings, and public outreach, but very few are mining the massive amounts of data available for use in disaster response. The research reflected in this paper strives to help emergency management practitioners harness the power of community volunteered information in a way that is still novel in most parts of the country. Field verification and research combined with survey results attempts to identify and solve many of the barriers to adoption that currently exist. By helping practitioners understand the virtues and limitations of this type of data and information, this research will encourage the use of community volunteered information in the emergency operations center.

Abstract: In this paper, we describe the design, implementation, and evaluation of a mesh network based messaging application for the One Laptop Per Child XO laptop. We outline the creation of an easy-to-use OLPC Activity that exchanges Ushahidi-style messages with nearby OLPC users through the Internet or a mesh network. Our contributions are to implement an epidemic messaging scheme on mesh networks of OLPC XO laptops, to extend the Ushahidi web application to efficiently exchange messages with nodes in mesh networks, and to allow the Ushahidi server to distribute cures, notifications of message delivery, for each received message. Testing and analysis revealed substantial overhead is introduced by the OLPC's use of Telepathy Salut for activity sharing.

Fortier F. F. T. Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 906–911). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: This paper analyses the collaborative dynamic of community in response to urgent situations. Community emergencies arising from natural or man-induced threats are considered as exogenous events that stimulate community resources to be unified around the response, action, and recovery activities related to the emergency. A structured equation model is derived to depict the actions of the community system. The system is described in terms of its resources including the propensity to trigger community action and collaboration among diverse groups. The community is profiled with respect to its ability to respond. The system defines the trigger mechanisms that are considered to be the drivers of collaborative action. A simulation model is presented to enact the system emergencies, community profiles, and collaborative response. The results develop an improved understanding of conditions that engage community collaborative actions as illustrated by examples from community research in the EnRiCH and the C-Change community research projects.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: In urban search and rescue (USAR) situations resources are limited and workload is high. Robots that act as team players instead of tools could help in these situations. A Virtual Reality (VR) experiment was set up to test if team performance of a human-robot team increases when the robot act as such a team player. Three robot settings were tested ranging from the robot as a tool to the robot as a team player. Unexpectedly, team performance seemed to be the best for the tool condition. Two side-effects of increasing robot's teammembership could explain this result: Mental workload increased for the humans who had to work with the team-playing robot, whereas the tendency to share information was reduced between these humans. Future research should, thus, focus on team-memberships that improve communication and reduce cognitive workload.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: A convenient way to test Urban Search And Rescue (USAR) robots would be in virtual environments (VEs). Evaluations in VEs are generally accepted as alternative for real scenarios. There are obvious differences between operation in a real and virtual environment. Nonetheless, the current experiment showed no significant differences in situation awareness (SA) and performance during several elementary tasks (e.g. slalom) between a virtual world and a previous experiment in reality (Mioch, Smets, & Neerincx, 2012). Only small dependencies between the unit tasks were found. The effect of individual differences (like gender, km driven per year, and gaming experience), were significant for certain elementary tasks. Testing robots in virtual environments could still be useful even if differences between VE and reality exist, since comparisons of different conditions in VE seems to have the same results as the same comparison in the field (Bishop & Rohrmann, 2003; Van Diggelen, Looije, Mioch, Neerincx, & Smets, 2012).

Abstract: This work in progress paper discusses analytically characterizing nonlinear recovery behavior through the context of the derecho windstorm that struck the mid-Atlantic United States in the summer of 2012. The focus is on the recovery efforts of the Appalachian Power Company, and the discussion includes a look at the need for communicating the progress of such recovery efforts to the public. Publicly available recovery data is analyzed and compared with respect to the relative behaviors exhibited by two different nonlinear recovery processes, and some of the implications for understanding the efficiency of different disaster recovery operations are discussed.

Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 780–790). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Recent studies have called attention to the improvement of “collaborative resilience” by fostering the collaboration potentials of public and private stakeholders during disasters. With our research we consider real and virtual volunteers in order to detect conditions for cooperation among those citizen groups through social media. Therefore we analysed the usage of Twitter during a tornado crisis to look for role patterns and aspects that helped volunteer groups in the virtual to emerge, and matched the data with an interview study on experiences, attitudes, concerns and potentials professional emergency services recounted in the emergence of volunteer groups in the real. While virtual groups seem to easily form and collaborate, the engagement of real volunteers is decreasing according to the perception of professionals. We discuss the dynamics in both tendencies and suggest design implications (use of existing social networks, promotion and awareness, connection among volunteers, connection to emergency services and systems) to support both types of volunteer groups, which lead to a software prototype.

Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 884–889). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Crisis communication during power outages poses several challenges. Frist, the causes of power outages are often events such as severe weather, which also lead to complications. Second, power outages themselves lead to limitations in everyday life. Third, communication infrastructures, that are necessary for crisis communication, are often affected. This work focuses on the communication of the organizations responsible for recovery work (emergency services, public administration, energy network operators) to the public affected by the power outage. Therefore this paper investigates the perception and the information demands of citizens and communication infrastructures in different scenarios. Taking the users' needs into consideration, an Information and Communication Technology (ICT) based concept for crisis communication, which combines general information with location-specific and setting-specific information was implemented as a prototype smartphone application and evaluated with 12 potential end users. ICT-based concepts can gain acceptance, however they should be understood as supplemental for some target groups and in some scenarios.

Abstract: On 15 June 2011, the ice hockey Stanley Cup final series between the Vancouver Canucks and the Boston Bruins took place in Vancouver. As the Vancouver Canucks were losing, riots started in downtown Vancouver. Social media were used to communicate between authorities and citizens, including the rioters. The media reporting on these events frame these communications with different narratives, which in turn raise different ethical considerations. This paper identifies those narratives and reflects upon the ideas of justice, fairness, responsibility, accountability and integrity as key ethical considerations. The paper also identifies some difficulties arising from the use of social media in crisis situations.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Emergency plans are developed to serve as a basis for response actions required in real situations. However, plan development is not an easy task and usually relies on complex processes. Due to the uncertainty of emergencies, one of the most challenging tasks is the development of possible courses of action. To deal with this uncertainty, we propose the use of scenario techniques for the definition of courses of action. Specifically, we adopt the use of CIA-ISM scenario technique for structuring the chain of events that can occur in a crisis that would support planning teams to develop courses of action. A practical application of the methodology has been successfully conducted by an emergency planning team in Brazil. The practical application of the CIA-ISM process was supported by a software artifact called CAEPlan. Lessons learned about the empirical application of both the methodology and the software artifact are presented.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: An emergency plan is an important artifact used throughout emergencies. Therefore, it is crucial that this plan covers the different scenarios faced by emergency team and that the prescribed procedures generate the desired results. To achieve these goals, emergency plans need to be exhaustively tested prior to its adoption. Emergency teams usually use simulation to test plans, but it is an expensive approach, demanding the building of complex environments and tools to get realistic situations. To be ready to go through a simulation exercise, a plan should not have many or critical mistakes, otherwise the simulation exercise would be wasted. We present a paired approach to evaluate emergency plans before simulation exercises, by applying software engineering testing techniques: Formal technical review (FTR) and mutation testing. The expected result is a plan more ready to go through simulation, as many of the mistakes are eliminated prior to simulation.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Post hoc evaluations made of crisis situations and exercises often point at communication as an important reason for the failure of the management and coordination of the crisis. Crisis managers have to deal with the problem that they (and all other actors in the field) don't have the right information to coordinate the efforts and solve the crisis situation. This paper examines the relation between the information available – more specifically the richness of the information and the distribution of the information – And the management and coordination of a typical man-made fast-burning crisis. The literature on decision making and situation awareness is reviewed and an experiment is conducted with 40 crisis managers in Belgium to assess the impact of the information. Initial results indicate a relationship between the ways a crisis team receives information and the achieved level of situation awareness, the difficulty of making decisions and the perceived complexity of the crisis.

Abstract: The study presented in this paper has investigated how technology can support spatial awareness when moving in wooded terrain. By “spatial awareness”, we refer to the ability to point in the approximate direction of several objects while navigating in unknown terrain. The ability to localize objects in the terrain has importance for emergency operations, for example firefighting and search and rescue operations. A field experiment was conducted with two conditions, one with technical support and one without. The results show that technical support in terms of GPS, digital maps and electronic compass can dramatically improve the ability to accurately indicate directions to objects. Further, findings concerning use of tests on spatial orientation to predict the ability to indicate directions to objects in the terrain when having no technical support are presented.

Abstract: This research uses multiple methods to investigate the use of an enterprise mobile multimedia information system aimed at improving handover of patient and emergency incident information from pre-hospital Emergency Medical Services (EMS) to hospital emergency department providers. A field study was conducted across EMS and hospital organizations in the Boise, Idaho region of the United States for three months to examine use of the system and to assess practitioner perspectives. Findings include perceived benefits and challenges to using digital audio recordings and digital pictures, captured using a smartphone application, for improving the timeliness, completeness, accuracy, convenience, and security of patient information for handover in EMS; limitations on how much data can be collected in the field due to a wide variety of contextual constraints; and a need to better understand the value of video within the EMS handover context.

Abstract: This practitioner report describes a moor- And turf-fire that occurred in 2011 at the Dutch-German border and was engaged by forces both from the Netherlands and Germany. All involved emergency management organizations were facing interoperability issues when it came to cross-border cooperation, although cooperation handbooks were already in use and the involved organizations were used to work together. The size of the incident and it's remote location called for an increased coordination between all involved actors and across all command levels.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Information is the most valuable resource for coping and recovery work in crisis management. It is the foundation for coordination, collaboration and decision-making. However, several challenges face information retrieval, evaluation and exchange processes in inter-organizational crisis management. On the one hand, due to the dynamic nature of crisis situations, information demands are hardly predictable and change in the course of time. Moreover, inter-organizational issues like terminology issues, policy constrains or even the lack of awareness about information available are influencing factors and need to be considered in designing appropriate ICT. In this paper we report from an empirical study, where we had a closer look on information retrieval and exchange practices in scenarios of medium to large power outages in Germany on an interorganizational level. Derived from these results, we were able to present a reference implementation of an interorganizational information repository (IOIR) and report our findings from a related evaluation.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Disaster recovery operations rarely proceed smoothly and disruptions often require the redistribution of relief items. Such a redistribution has to be carried out taking into account both the current disruption and the uncertainty regarding possible future incidents in the respective area. As decisions have to be made fast in humanitarian operations, extensive optimization runs cannot be conducted in such a situation. Nevertheless, sensible decisions should be made to ensure an efficient redistribution, considering not only satisfaction of needs but also operational costs, as the budget is usually scarce in the recovery phase of a disaster. In this work, different scenarios are generated and then solved with a multiobjective optimization model to explore possible developments. By evaluating the results of these scenarios, decision rules are identified which can support the decision maker in the actual disaster situation in making fast, but nevertheless well-founded, decisions.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Real-time information from microposts like Twitter is useful for applications in the crisis management domain. Currently, that potentially valuable information remains mostly unused by the command staff, mainly because the sheer amount of information cannot be handled efficiently. Sentiment analysis has been shown as an effective tool to detect microposts (such as tweets) that contribute to situational awareness. However, current approaches only focus on two or three emotion classes. But using only tweets with negative emotions for crisis management is not always sufficient. The amount of remaining information is still not manageable or most of the tweets are irrelevant. Thus, a more fine-grained differentiation is needed to identify relevant microposts. In this paper, we show the systematic evaluation of an approach for sentiment analysis on microposts that allows detecting seven emotion classes. A preliminary evaluation of our approach in a crisis related scenario demonstrates the applicability and usefulness.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: This paper examines the problem of achieving efficient inter-organizational collaboration during emergency response. The authors interviewed 11 representatives from Norwegian emergency agencies and supporting organizations about a hypothetical scenario involving a large-scale chemical incident. The interviews resulted in the identification and categorization of more than 45 actors that would be involved in the response effort, clarification of the individual capabilities and knowledge those actors would possess, and descriptions of how they would interact and communicate with each other. The results illustrate the complexity and necessity of achieving inter-organizational collaboration by showing how capabilities and knowledge are distributed and communicated across different actors, and suggest that such communications are mainly verbal. Based on this, the paper discusses challenges and opportunities for improving inter-organizational collaboration in the future.

Abstract: The hypothesis of this study is that collaboration between fire and rescue services and new actors, with basic rescue skills, might be a cost effective way to improve emergency response. Interview studies of collaborations between fire and rescue services and security officers in three Swedish municipalities are presented. Seven semi-structured interviews are conducted with representatives from the security officer companies, the fire and rescue services and security managers at the municipalities. The method used to evaluate the collaborations quantitatively is Cost-benefit analysis. The collaborations have positive economic effects for society that most likely outweighs the costs. There also exist several external effects that are not possible to value monetarily, but that represent positive values for society. The results and their generalizability are discussed, as well as the possibility for these new collaborations to improve crisis management.

Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 120–124). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: A major crisis or disaster attracts a response from multiple organizations. These organizations need to work together as a coalition. To do so effectively, they must share information. Differences in organizational culture give information a scarcity value, leading to the emergence of information markets. As the crisis progresses, organizations learn to work together, building up trust and lowering the “price” for information shared. Organizations that have worked together in previous crises have a price advantage. In short, the information sharing changes dynamically. Evolutionary game theory – And the minority game in particular – has been recently applied to markets in which physical goods are exchanged. This paper presents the first results from simulating an information sharing market in crisis response coalitions as a minority game.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Crisis situations generate tens of millions of social media reports, many of which contain references to geographic features and locations. Contemporary systems are now capable of mining and visualizing these location references in social media reports, but we have yet to develop a deep understanding of what end-users will expect to do with this information when attempting to achieve situational awareness. To explore this problem, we have conducted a utility and usability analysis of SensePlace2, a geovisual analytics tool designed to explore geospatial information found in Tweets. Eight users completed a task analysis and survey study using SensePlace2. Our findings reveal user expectations and key paths for solving usability and utility issues to inform the design of future visual analytics systems that incorporate geographic information from social media.
