Most of the climate and natural hazards are closely related to design, construction and maintenance, and have to be effectively transferred to practice of management agencies and maintenance companies. The paper presents a general assessment of the management and organizational bases for conducting actions during emergency events for entities in the region that are the most important link in the whole chain - road maintenance companies.

In an age where all major manufacturers are trying to get a better understanding of when an emergency response should be triggered, it becomes imperative to learn how humans respond to emergency events. If one can understand driver behavior, systems can be designed around the user to either assist drivers where they fail to perform well or completely eliminate them from the accident avoidance maneuver. In this study, 169 crash and near crash events from the SHRP2 dataset were analyzed. The response behavior of drivers was measured in events where the through drivers’ path was intruded upon by another vehicle perpendicular to its path. Overall, drivers responded significantly faster when the other vehicle failed to stop, and at intersection locations.

Natural hazards (also known as ground movement or geohazards) can cause pipeline failures, with consequences ranging from injury/death, environmental impact, and property damage, to lengthy service disruption and a failure to achieve delivery targets. In North America and western Europe, pipeline failure resulting from natural hazards are typically rare (but costly) events. However, where difficult ground conditions have not been properly accounted for in pipeline design, construction, and operation, natural hazards may have an overriding influence on pipeline risk and reliability. These issues are discussed, and a framework for estimating the influence of natural hazards on pipeline risk and system reliability is introduced.

Emergency Events

Emergency events affect human security and safety as well as the integrity of the local infrastructure. Emergency response officials are required to make decisions using limited information and time. During emergency events, people post updates to social media networks, such as tweets, containing information about their status, help requests, incident reports, and other useful information. In this research project, the Latent Dirichlet Allocation (LDA) model is used to automatically classify incident-related tweets and incident types using Twitter data. Unlike the previous social media information models proposed in the related literature, the LDA is an unsupervised learning model which can be utilized directly without prior knowledge and preparation for data in order to save time during emergencies. Twitter data including messages and geolocation information during two recent events in New York City, the Chelsea explosion and Hurricane Sandy, are used as two case studies to test the accuracy of the LDA model for extracting incident-related tweets and labeling them by incident type. Results showed that the model could extract emergency events and classify them for both small and large-scale events, and the model’s hyper-parameters can be shared in a similar language environment to save model training time. Furthermore, the list of keywords generated by the model can be used as prior knowledge for emergency event classification and training of supervised classification models such as support vector machine and recurrent neural network.

Geosciences are developing and applying a wide range of methodologies to assess natural hazards. Significant advances in the site characterization and models development have been achieved in the last decade, but many challenges still remain. Several disastrous earthquakes in the past decade accompanied with tsunamis have required a rapid assessment of the underlying causes of the tragic loss of life and property. Natural disasters risk reduction and control as a crucial criterion for sustainable development and minimizing social and economic loss and disruption due to earthquakes, tsunamis and other hazards requires reliable assessment of the seismic and tsunami hazard, as well as mitigation actions of the vulnerability of the built environment and risk. All of these provide the critical basis for improved building codes and construction emergency response plans for the people and infrastructure safety and protection.

Emergency Events

Response organizations often face serious challenges as a result of communication problems during emergency events. This can to a large extent be traced to the tradition of verbal communication in this context. Issues in communication translate to matters of sensemaking, planning, and collaboration among distributed response teams. This paper reports from an interview study with emergency managers regarding the work conducted during a wildfire. Boundary objects and sensemaking were used as analytical lenses, emphasizing how outcome of sensemaking activities are used at different sites and interpreted differently in different work settings. Challenges of verbally exchanging complex information regarding location and geography, between individuals and groups, make us reconsider the role of technology and its potential to support efficient interactions, which will limit ambiguity and uncertainty, and increase accuracy, articulation, and persistence.

Post Disaster

As a result of the earthquakes that occurred in September 1985 and their human and material consequences, disaster care in Mexico became institutionalized and acquired the rank of public policy when the first national civil protection law was published years later. More than 30 years after the creation of the National Civil Protection System, there have been some important advances; however, they have not been translated into higher levels of safety for populations exposed to risk. On the contrary, the evidence shows that the country’s risk, as well as the number of disasters and associated material losses, increase year by year. To a large extent, this stems from an approach based predominantly on post-disaster response by strengthening preparedness and emergency response capacities and creating financial mechanisms to address reconstruction processes, as opposed to broader approaches seeking to address the root causes of risk and disasters. Post-disaster actions and reconstruction processes have failed to achieve acceptable levels of efficiency, and disorganization and misuse of resources that should benefit disaster-affected populations still prevails.

Practical Implications

Purpose – The purpose of this paper is to identify lessons learned by schools from their involvement in the 2012 New Zealand ShakeOut nationwide earthquake drill. Design/methodology/approach – The results from a survey conducted with 514 schools were collated to identify the emergency preparedness lessons learned by schools through their participation in the ShakeOut exercise. Findings – Key findings indicated that: schools were likely to do more than the minimum when presented with a range of specific emergency preparedness activities; drills for emergency events require specific achievement objectives to be identified in order to be most effective in preparing schools; and large-scale initiatives, such as the ShakeOut exercise, encourage schools and students to engage in emergency preparedness activities. Practical implications – Based on the findings, six recommendations are made to assist schools to develop effective emergency response procedures. Originality/value – The present study contributes to the ongoing efforts of emergency management practitioners and academics to enhance the efficacy of school-based preparedness activities and to, ultimately, increase overall community resilience.
