How representative are local building insurers' claims to assess winter windstorm risk? In our case study of Zurich, we use a risk model for windstorm building damages and compare three different inputs: insurance claims and historical and probabilistic windstorm datasets. We find that long-term risk is more robustly assessed based on windstorm datasets than on claims data only. Our open-access method allows European building insurers to complement their risk assessment with modelling results.

The choice of residential location is one of the drivers shaping risks in cities. We model likely outcomes of this decision-making process for distinct socioeconomic groups in the city of Leipzig, Germany, using random forests and geostatistical methods. In so doing, we uncover hot spots and cold spots that may indicate spatial patterns and trends in exposure and vulnerabilities of urban population, to shed light on how residential location choice affects these risk components as a process.

This paper draws on the experiences of seven early career scientists, in different sectors and contexts, to explore the improved integration of natural hazard science into broader efforts to reduce the likelihood and impacts of disasters. We include recommendations for natural hazard scientists, to improve education, training, and research design and to strengthen institutional, financial, and policy actions. We hope to provoke discussion and catalyse changes that will help reduce disaster risk.

Large volcanic eruptions are rare events; however, they may cause significant economic losses. This work explores a specific type of insurance (parametric insurance) applied to such events. Unlike traditional insurance where payouts occur after often lengthy loss assessments, this type of insurance makes automatic and prompt payments on the basis of the eruption attaining threshold values for objective and easily measurable characteristics (height and direction of the eruption column).

The article provides a comparison of a standard (deterministic) risk assessment approach for roads exposed to a multi-hazard environment with a probabilistic risk analysis method to show the potential bias in the results. A probabilistic approach enables the quantification of epistemic uncertainty and uses probability distributions to characterize data uncertainty of the input variables, while a deterministic computation uses single values with discrete values without uncertainty representation.

Flood risk management requires a realistic estimation of flood losses. However, the capacity of available flood damage models to depict real damages is questionable. With a joint effort of eight research groups, the objective of this study was to compare the performances of nine models for the estimation of flood damage to buildings. The comparison provided more objective insights on the transferability of the models and on the reliability of their estimations.

INSYDE is a multivariable synthetic model for flood damage assessment of dwellings. The analysis and use of this model highlighted some weaknesses, linked to its complexity, that can undermine its usability and correct implementation. This study proposes a simplified version of INSYDE which maintains its multivariable and synthetic nature but has simpler mathematical formulations permitting an easier use and a direct analysis of the relation between damage and its explanatory variables.

We develop a framework that links the volume of hydraulic fracturing fluid injected during shale gas exploration with the likelihood that resulting seismicity causes a nuisance to nearby populations. We apply the framework to a shale gas site in England and find that the potential of a given injected volume to produce nuisance ground motions is especially sensitive to assumptions about the amount of seismic energy released during operations. The work can inform policy on shale gas exploration.

Flood risk management is especially complicated in coastal cities. The complexity of multiple flood hazards in a rapidly changing urban environment leads to a situation with many different potential measures and future scenarios. This research demonstrates a new model capable of quickly simulating flood impact and comparing many different strategies. This is applied to the city of Beira, where it was able to provide new insights into the local flood risk and potential strategies.

This study establishes an indicator system for social vulnerability evaluation of storm surges for coastal cities. The indicator system is applied to Shenzhen, China, and socioeconomic impacts are discovered in the results. Exposure, sensitivity, and resilience all show an increasing trend from 1986 to 2016, as resilience accounts for the largest increase and is connected to a decreasing social vulnerability trend.

Although disaster experience does indeed play an important role in helping people become aware of earthquake risk, disaster experience does not necessarily increase people’s willingness to retrofit their houses. People with higher education and certain occupations represent those who might have more available resources, and therefore they might become more willing to prepare for and respond to disasters.

Asset damage caused by tropical cyclones is often computed based on impact functions mapping wind speed to damage. However, a lack of regional impact functions can lead to a substantial bias in tropical cyclone risk estimates. Here, we present regionally calibrated impact functions as well as global risk estimates. Our results are relevant for researchers, model developers, and practitioners in the context of global risk assessments, climate change adaptation, and physical risk disclosure.

There is increasing interest and need to analyze the contribution of anthropogenic climate change to negative impacts of climate change. We study the case of glacial lake Palcacocha in Peru, which poses a significant flood risk to the city of Huaraz. We found that greenhouse gas emissions; strong urbanization processes without appropriate land use planning; and social, cultural, political, and institutional factors all contribute to the existing flood risk.

A localized empirical model consisting of multilevel parameters has been built to evaluate the flood vulnerability of residential buildings in a heritage community of Kuala Lumpur, Malaysia. A new economic loss model is developed to quantify the flood risk in terms of replacement cost, taking into account both specific vulnerability and a normalized depth–damage ratio function. The findings provide multiscale flood-resistant strategies for the protection of individual residential buildings.

Mitigation planning and economic loss assessment generally rely on flood damage prediction models. However, unavailability of empirical data has limited the use of such models in data-scarce areas. This paper combines the vulnerability indicator and damage grade approach to develop a conceptual framework for predicting building damage in data-scarce regions. The framework can be implemented using only expert knowledge and facilitates transferability of flood damage models in data-scarce areas.

Using the information of the author's database, contributions of natural hazards and adverse weather to occurrences of different types of transport accidents and traffic disruptions including road, railway, air, and water transport were revealed. Regional differences in the risk of transport accidents and traffic disruptions caused by adverse natural impacts between Russian federal regions were found. The resulting maps were created and analyzed. Regions most at risk were identified.

Probabilistic seismic risk analysis is widely used in the insurance industry to model losses to insured portfolios by earthquake events. Risk items are often only known to be located within an administrative geographical zone, but precise coordinates remain unknown to the modeler. We analyze spatial seismic hazard and loss rate variation inside administrative zones in western Indonesia. Building upon this, we present a novel framework for efficient treatment of portfolio location uncertainty.

Effective flood management requires information about the potential consequences of flooding. We show how openly accessible data from OpenStreetMap can support the estimation of flood damage for residential buildings. Working with methods of machine learning, the building geometry is used to predict flood damage in combination with information about inundation depth. Our approach makes it easier to transfer models to regions where no detailed data of flood impacts have been observed yet.

The study provides a comprehensive assessment and zonation of hazard, vulnerability, and risk of storm surge caused by the designed typhoon scenarios in the coastal area of Huizhou. The risk maps can help decision-makers to develop evacuation strategies to minimize civilian casualties. The risk analysis can be utilized to identify risk regions to reduce economic losses. The proposed methodology and procedure can be applied to any coastal cities in China for making risk assessments.

This study presents a first-of-its-kind pre-drilling probabilistic induced seismic risk analysis for the Geldinganes (Iceland) deep-hydraulic stimulation. The results of the assessment indicate that the individual risk within a radius of 2 km around the injection point is below the safety limits. However, the analysis is affected by a large variability due to the presence of pre-drilling deep uncertainties. This suggests the need for online risk updating during the stimulation.

Natural hazards have an increasing impact on transportation networks. In order to analyze it we developed Network-risk – an open toolbox for ArcGIS. The toolbox links input data such as network datasets (also OpenStreetMap – OSM – data), traffic values or segments which can be affected, determining the difficulty to reach an area and enabling evaluation of socioeconomic implications. By testing Network-risk for Bucharest we show areas difficult to reach by emergency units in earthquakes.

Multi-hazard risk assessment of cultural heritage assets is of primary importance in natural-hazard-prone areas, particularly for the prioritization of disaster risk reduction and resilience-enhancing strategies. This paper introduces a multi-hazard risk prioritisation framework specifically developed for cultural heritage assets. The proposed framework relies on a multi-level rapid-visual-survey form for the multi-hazard data collection and risk prioritization of case-study assets.

Bathing water quality at public beaches is often compromised by the presence of urban sewer systems that usually discharge, mostly during rainfalls, untreated sewer water into lakes, rivers or seas. In this study we analyzed and quantified the impact of sewer discharges into the sea of a large Spanish city. This study provides a useful idea for local water managers and for people bathing in these areas about how long and how much an urban sewer system can affect the seawater quality.

Recovering from major earthquakes is a challenge due to a destablized environment. Over 11 years, we monitored a region hit by the Wenchuan earthquake, finding the loss caused by postseismic hazards was more than that caused by the earthquake. The main reason was a rush in reconstruction without proper hazard and risk assessment. It was concluded that postseismic recovery should consider not only spatial but also temporal dynamics of hazards as well as possible interaction among hazards.

We review the scientific literature on natural hazard risk assessments at the global scale. In doing so, we examine similarities and differences between the approaches taken across the different hazards and identify potential ways in which different hazard communities can learn from each other. Finally, we discuss opportunities for learning from methods and approaches being developed and applied to assess natural hazard risks at more continental or regional scales.

The objective of this article is to propose a spatial decision support tool based on geovisualization techniques and a resilience assessment method for flood risk management. The methodology proposed integrates decision-making by identifying characteristics of urban resilience to facilitate its understanding with a visual tool. Results demonstrate a way to operationalize the concept of resilience at a local scale, integrating local stakeholders into a participative process.

We present a framework to evaluate the benefits and costs of coastal adaptation through dikes to reduce future flood risk. If no adaptation takes place, we find that global coastal flood risk increases 150-fold by 2080, with sea-level rise contributing the most. Moreover, 15 countries account for 90 % of this increase; that adaptation shows high potential to cost-effectively reduce flood risk. The results will be integrated into the Aqueduct Global Flood Analyzer web tool.

The paper focuses on psychological impacts of river floods and flash floods on affected individuals. Since the connection between psychological characteristics and protection motivation is not yet fully understood, potential coherences are investigated with regard to both flood types. As a main result, the frequency of remembering an event seems to be positively connected to a greater willingness to protect oneself, especially if affected by a weaker flood event.

To consider potential future urban developments in pluvial flood risk assessment, we develop empirical relationships for imperviousness and flood damage based on an analysis of existing urban characteristics. Results suggest that (1) data resolutions must be carefully selected, (2) there are lower limits for the spatial scale at which predictions can be generated, and (3) depth-dependent damage estimates are challenging to reproduce empirically and can be vulnerable to simulation artifacts.

Due to the specific applicability of drought impact indicators, this study identifies which drought indicators are suitable for characterising drought impacts and the contribution of vulnerability factors. The results show that the relationship varies across different drought impacts and cities; some factors have a strong positive correlation with drought vulnerability. This study can support drought planning work and provide background for the indices used in drought monitoring applications.

The Amazon rainforest is being destroyed, resulting in negative ecological and social impacts. We explore how stakeholders perceive the causes of the Amazon's degradation in Bolivia and Brazil and develop a series of scenarios to help strengthen the balance between human development and environmental conservation. The results suggest that the application of governance and well-integrated technical and social reform strategies encourages positive regional changes even under climate change.

The paper presents, for the first time, a global-scale drought risk assessment for both irrigated and rainfed agricultural systems while considering drought hazard indicators, exposure and expert-weighted vulnerability indicators. We identify global patterns of drought risk and, by disaggregating risk into its underlying components and factors, provide entry points for risk reduction.

Field surveys after major disastrous earthquakes have shown that poor performance of buildings in earthquake-affected areas is the leading cause of human fatalities and economic losses. The evaluation of seismic fragility for existing building stocks has become a crucial issue due to the frequent occurrence of earthquakes in the last decades. This study conducts such a comprehensive review for mainland China and aims to better serve the natural disaster prevention and mitigation cause in China.

Assessing the risk of complex systems to natural hazards is an important and challenging problem. In today’s socio-technological world, the connections and interdependencies between exposed elements are crucial. These complex relations call for a paradigm shift in collective risk assessment. This paper proposes a holistic, graph-based approach for assessing the risk of complex systems. The feasibility of the approach is discussed by an application to a pilot study in Mexico City.

Post-event field survey data from two tsunami events, the 2011 Tōhoku tsunami, Japan, and the 2015 Illapel tsunami, Chile, are used in this study to develop fragility functions for roads and bridges. This study demonstrates the effectiveness of supplementing post-event field surveys with remotely sensed data. The resulting fragility functions address a substantial research gap in tsunami impacts on infrastructure and include a range of subtleties in asset and hazard characteristics.

The methodology presented in this paper is considered an important entry point to addressing the complex problems related to disaster resilience. Regardless of storms, hurricane impact on local employment is found to be either temporary or permanent in nature. Relating the concept of resilience to observable socioeconomic activities helps us gain a deeper understanding of the drivers and processes of post-storm recovery. Studies play a major role in bridging knowledge gaps.

Houses and their contents in Europe are worth trillions of euros, resulting in high losses from natural hazards. Hence, risk assessments need to reliably estimate the size and value of houses, including the value of durable goods kept inside. In this work we show how openly available or open datasets can be used to predict the size of individual residential buildings. Further, we provide standardized monetary values of houses and contents per square metre of floor space for 30 countries.

Sandbag and sandbag replacement systems (SBRSs) for flood defence are compared in terms of functionality (practical tests), costs, time, helpers and logistics (fictitious realistic scenarios). SBRSs are comparable in their functionality to sandbagging. All of the SBRSs considered show time-saving and logistical advantages. Under the assumed conditions, the higher investment costs of the SBRSs are offset with one subsequent reuse of the system owing to lower costs for helpers and logistics.

Emergency medical service (EMS) response is important for pre-hospital lifesaving, but disasters increase the difficulty of rescue, which increases the pressure on EMS facilities. In order to avoid the failure of EMS facilities during disasters, we propose a multi-coverage optimal location model for EMS facilities based on results of disaster risk assessment. Results showed that the optimized EMS locations reduced the delay in response and significantly increased the number of rescued people.

This paper describes a replicable approach for characterising interactions between natural hazards. Guatemala is exposed to multiple natural hazards, which do not always occur independently. There can be interactions between natural hazards. For example, one hazard may trigger multiple secondary hazards, which can subsequently trigger further hazards. Here we use diverse evidence of such interactions to construct matrices of hazard interactions in Guatemala at national and sub-national scales.

With the aim of improving resilience to flooding, this paper presents a methodology for creating a wide database of hypothetical levee-breach scenarios obtained from 2-D numerical modelling. The results can support civil protection activities during emergency planning and management, increasing preparedness against floods. The methodology is applicable to any lowland area protected by river levees. An example of the outcome concerning a pilot area in northern Italy is presented here.

A vulnerability assessment method is proposed to identify the most vulnerable regions over Portugal. Two methods were compared, namely a subjective categorical method and an automatic method, based on drought indicators, vegetation indices and soil variables. Both methods present similar results, and both identify Minho (Alentejo) as having low (extreme) vulnerability. The automatic method has advantages, as it is fully statistical and presents results without prior knowledge of the region.

The paper presents AGRIDE-c: a conceptual model for the estimation of flood damage to crops. The model estimates both the physical damage on the plants and its economic consequences on the income of the farmers. This allows AGRIDE-c to support effective damage mitigation strategies, at both public and individual farmer levels. The model can be adapted to different geographical and economic contexts, as exemplified by its implementation for the context of northern Italy.

To limit the losses due to floods, people can adopt measures to protect their dwellings. We assessed the cost and efficacy of such measures using computer modelling. We found that the benefits of most of the measures studied are unlikely to exceed their cost when they are taken in dwellings that are not exposed to frequent floods (probability of occurrence of less than 1 / 100 per year). It is also often less expensive to use building materials adapted to floods than other common materials.

One of the main volcanic processes affecting road bridges are lahars, which are flows of water and volcanic material running down the slopes of a volcano. In this paper, bridge failure models due to lahars are proposed and, based on these, fragility curves are developed. Fragility curves are parameterized by maximum likelihood estimation, assuming a cumulative log-normal distribution. Bridge failure models are empirically evaluated using data of 15 bridges that were affected by lahars.
