This document discusses different models for estimating shelter requirements after earthquakes: SYNER-G, HAZUS-MH, ERGO-EQ, MCEER, InaSAFE, and RiskScape. It provides an overview of the conceptual frameworks and parameters considered in each model's calculations of displaced populations and shelter needs. These parameters include building damage, age, income, ethnicity, and others. The document also compares the outputs produced by each model, such as estimates of population displacement by geographic area or dwelling units. Future developments proposed include tailoring models to specific contexts and incorporating additional social and cultural factors.

The document discusses a study examining how well UK water service providers incorporate risk management and resilience as part of a multi-agency approach. The researchers analyzed 38 Community Risk Registers and found inconsistencies in style, structure, and level of detail when assessing risks like water infrastructure failures or drought. They conclude that improved consistency is needed in how water providers engage in and contribute their risk assessments to the community planning process.

The document presents a seismic risk assessment model for a hospital's emergency department (ED). The model includes physical, functional, and patient-oriented submodels linked together. The physical submodel uses structural analysis to determine floor accelerations and drift from ground motions. The functional submodel assesses loss of functionality to examination and operating rooms. The patient-oriented submodel models patient flow through the ED and calculates performance indices based on waiting times. The full model is used to predict ED performance in an earthquake scenario and provide a seismic risk analysis framework.

This document summarizes key points from an OECD report on risk communication by governments and the role of social media in crisis communication. It discusses how effective risk communication is important for public trust, costs, and policy learning. Risk communication systems should include stakeholders, focus on prevention, and facilitate two-way information sharing using new technologies like social media. Social media can help spread information faster than traditional media, though it also presents challenges around speed of response, misinformation, and message confusion. The report identifies 12 good practices for governments to develop multi-layered social media strategies in partnership with citizens and traditional media.

This document summarizes a presentation on integrative risk assessment and management for residential recycled water schemes in Australia. It introduces residential recycled water schemes and their objectives to reduce potable water demand, effluent discharge, and stormwater runoff. It then shows that few schemes in Australia have been successful long-term. Through historical analysis and industry surveys, it identifies key risks to schemes' long-term viability like public health concerns, economic challenges, and regulatory issues. The presentation argues current risk assessment and management practices have limitations like poorly defined objectives and an independent approach that does not consider time and context adequately. Improved integrative risk management is needed for resilient recycled water schemes.

The document presents a framework called the Context Capacity and Performance Model of Local Government Disaster Risk Reduction (DRR). It aims to understand the drivers and barriers to DRR action by local governments. The model hypothesizes relationships between the context local governments operate in, their capacities for DRR, and their performance and action. An expert survey was conducted to validate the model and found experts had varying opinions, with context and capacity seen as equally influential, and all capacities viewed as similarly important, though financial capacity was overestimated and policy context was underestimated. More research is needed, including broader expert and local government surveys, and case studies applying the model.

1) The document analyzes data from surveys of Syrian refugees in Turkey to understand their choices regarding returning to Syria, staying in Turkey, or migrating elsewhere.
2) It finds that as the duration of living as a refugee increases, the probability of returning to Syria decreases significantly, while the likelihood of migrating to another country increases.
3) Refugees who experienced greater damage, losses, or deaths due to the war in Syria are less likely to return and more likely to migrate internationally in search of asylum.

Editor's Notes
Good evening ladies and gentlemen. My name is Julie Clarke and I’m here on behalf of Roughan and O’Donovan Innovative Solutions; a specialist consulting engineers with particular expertise in the field of risk-based asset management.
In this presentation, I’m going to discuss stress tests for critical transport infrastructure due to natural hazards. In particular, I’m going to focus on the application of a stress testing methodology to a case study that consists of a road network in Northern Italy.
Extreme natural hazard events, such as earthquakes, floods and landlsides can have potentially devastating consequences, as we are all too aware.
In addition to the tragic loss of human life, natural hazards events can cause significant damage to transport infrastructure, resulting in travel disruption and potential economic losses.
For example, the 6.8 magnitude Northridge earthquake that occurred in California in 1994 significantly impacted the regional transportation system in the area of Los Angeles and generated a year’s worth of highway repair work as a result of the single event.
The EU-funded INFRARISK project, entitled ‘Novel Indicators for Identifying Critical Infrastructure at Risk from Natural Hazards’, has developed a stress testing methodology to establish the resilience of critical transport infrastructure against extreme natural hazard events.
The project consortium consists of 11 partners from across Europe that include SMEs, research institutes & universities, and one large entreprise.
Roughan & O’Donovan Innovative Soltions are coordinators of the INFRARISK project and are also leading the case studies technical work package. I am going to introdcuce one of the INFRARISK case studies in this presentation. The objective of the case study is to demonstrate the systematic application of the methodologies and procedures that have been developed in the INFRARISK project.
This stress testing methodology being developed as part of the INFRARISK project is concerned with low probability, high consequence natural hazard events. Stress tests are commonly employed in the other sectors, such as the finance and nuclear power industries, to determine the impact of abnormal shocks on systems. Stress tests can be used to provide important insights in relation to critical transport infrastructure that can facilitate the decision making process with regard to the protection of these assets.
The INFRARISK project is focused on trans-European road and rail corridors. For Europe in particular, the singe market depends on an effective transport system to bring people together and to facilitate trade. It is estimated that road and rail networks account for 80% of passenger transport and 50% of goods transport throughout the EU.
The natural hazards that have been considered in the project include earthquakes, floods and landslides, and their cascading effects have also been considered, For example, earthquake-triggered landslides.
Stress tests enable the risk to be quantified in terms of the cost of physical infrastructure damage, the resulting delays for passenger and freight transport, and the associated economic losses due to the transport disruption.
The selected Italian road network case study is located in the province of Bologna, in the Emilia-Romanga region of Italy. The city of Bologna comprises a metropolitan area of approximately 1 million people and is one of the most important business centres in Italy.
There are over 600,000 work or study related passenger trips per day within the province of Bologna and the Emilia-Romagna region supports over 13% of Italy’s road freight transport per year.
The selected road network is located along the Scandinavian-Mediterranean TEN-T corridor; a crucial north-south axis for the European economy that provides an important transport link from the city of Bologna to the neighbouring Italian cities of Florence and Milan.
This slide shows the selected case study road network, which covers an area of nearly 1000km2 and consists of nearly 3500km of roadway. The motorway along the Scandinavian-Mediterranean TEN-T corridor is shown here in pink. The remaining roads are classified as either primary, secondary, tertiary, or local roads.
The province of Bologna is located in a seismically active region, as shown here according to the seismic hazard map that was developed as part of the European SHARE project.
Additionally, the province is moderately susceptible to landslides. Therefore, the stress tests were performed for the road network in terms of the seismic hazard and the associated earthquake-triggered landslide cascading effects.
The objective of the stress tests is to determine the losses associated with an adverse scenario. This scenario may be defined in terms of the hazards and/or the consequences, as will be shown for the Italian case study, and it is anticipated that the appropriate stress tests for transport infrastructure using this methodology in general will be specified using expert judgement.
The stress testing methdology developed in the INFRARISK project is performed according to a structured overarching risk assessment methodology, as shown in this diagram.
This methodology has been adopted for the Italian case study and a quantitative approach has been employed for the stress tests.
Initially, the system representation was specified in term of the hazards.
As previously mentioned, the INFRARISK project is focused on low probability, extreme natural hazard events. For earthquakes, ‘low probability’ refers to return periods that exceed those that are included in current design codes and an ‘event’ refers to a measure of ground motion intensity.
The ground motion field shown in this slide was specified using a seismic hazard model that was specifically developed within the project. The ground motion field is linked to a critical network element along the network – this element was identified using a method known as betweenness centrality, which is used to identify elements that, if removed, would effectively divide the network and cause significant transport disruption. In this case, the critical network element is a bridge along the TEN-T motorway.
The earthquake-triggered landslide cascading effects were considered by defining landslide yield acceleration values for the region. The landslide yield acceleration paraneter – ky - was specified using a rigid sliding block approach that determines the horizontal acceleration at which sliding initiates. Ky values were determined for the case study region based on slope values and geological information.
The system representation was also specified according to the structural vulnerability of the road network. In this case, the seismic vulnerability of the network bridges and tunnels was considered.
To do so, the location of the network bridges and tunnels was initially identified. In total, there are 340 road bridges and 30 road tunnels located along the selected case study network.
Structural characteristics were subsequently obtained for these bridges and tunnels according to a visual survey using Google maps. However, in many cases network managers will already have an existing database available.
Fragility functions were subsequently assigned to each structural element based on its structural characteristics. As shown here, fragility functions provide the probability of exceeding a defined damage state for a given level of loading due to the particular natural hazard being considered. For example, here the fragility functions indicate the probability of damage induced in a bridge as a result of ground shaking from an earthquake.
The fragility functions assigned to the bridges and tunnels along the Italian case study road network were obtained from existing databases that were developed in the European SYNER-G project and are defined in terms of four damage states: 1. Slight, 2. Moderate, 3. Extensive and 4. Complete damage.
In addition, the vulnerability of the roads to earthquake-triggered landslides was considered in the case study. To characterise the structural vulnerability of individual road sections to landslide-induced physical damage, the road network was initially divided up into road sections – 10m segments were considered in this case.
The fragility functions were defined in terms of three damage states: 1. Slight, 2. Moderate and 3. Complete damage and were subsequently assigned based on the value of ky and the road type using a method described by the reference shown here.
The system representation was also defined in terms of the infrastructure events, in other words, the potential funtionality loss of the road network.
This was characterised in terms of the defined damage states. For example, the following slide shows the functionality loss of the road in terms of % lane closure at the location of a bridge due to seismic-induced damage.
Additionally, the restoration duration and costs were defined for each damage state. Example durations and costs are shown here for a network bridge.
Finally, the system representation was defined in terms of the network use events; in other words the traffic demand for the road network.
To do so, origin-destination data was obtained for the Bologna region, which provided details of daily work- or study- related passenger trips and the associated origin and destination zones. For the selected case study region, 21 O-D zones were considered, as shown in this slide, and traffic modelling was performed using NEXTA software.
The traffic analysis consisted of a comparison of ‘normal’ network operations, in other words, no damage, to various post-hazard damage scenarios to quantify the associated impact in terms of journey delay times. Quantified travel time increases were subsequently used in conjunction with GDP values to determine the associated economic loss.
In this slide, example risk estimates are shown in terms of the total repair costs for the case study road network and the total cumulative restoration time. Of course, the actual duration of the restoration period will depend on the number of repair crews and the resources available.
The estimates are shown in terms of a probabilistic output as the uncertainty relating to the vulnerability of the network elements (the bridges, tunnels and road sections) was considered in the analysis (as characterised using fragility functions).
Evaluation of the risk will of course depend on the network manager or owner. However, such results can be used to assist in the decision-making process with regard to the prioritisation of intervention measures to improve the resiliance of critical infrastructure to extreme natural hazard events.
I hope this presentation has given you some insight into the methodologies and procedures that have been developed in the INFRARISK project.
It is worth noting that the project has also developed an online decision support tool to perform stress tests on road and rail networks.
In addition, the project is currently developing a training course for infrastructure managers/owners, decision makers, and others who may be interested in this subject matter.
More information can be found online – the website address is shown here.
I would like to briefly mention the final INFRARISK dissemintation conference, which will be held in Madrid at the end of next month. There is free registration for this event and those who are interested can contact our project partner CSIC at the address shown here or else you can contant myself.
Many thanks for listening and if anyone has any questions I’d be happy to answer them now.
