LISFLOOD-FP has been extended with new shallow-water solvers – DG2 and FV1 – for modelling all types of slow- or fast-moving waves over any smooth or rough surface. Using GPU parallelisation, FV1 is faster than the simpler ACC solver on grids with millions of elements. The DG2 solver is notably effective on coarse grids where river channels are hard to capture, improving predicted river levels and flood water depths. This marks a new step towards real-world DG2 flood inundation modelling.

This paper reports a brief history of volcanic risk in the Neapolitan district, where the presence of three active volcanoes (Vesuvius, Campi Flegrei caldera and Ischia island) exposes this highly urbanized area to hazard of potential eruptions. I am trying to obtain new food for thought for the scientific community working to mitigate the volcanic risk of this area, revisiting about 40 years of debates around volcanic risk in Naples.

Estimating flood damage, although crucial for assessing flood risk and for designing mitigation policies, continues to face numerous challenges, notably the assessment of indirect damage. We focus on flood damage induced by the interactions between economic activities. By modeling the production processes of a cooperative wine-making system, we show that these interactions are important depending on their spatial and temporal characteristics.

A grid-level residential building stock model (in terms of floor area and replacement value) targeted for seismic risk analysis for mainland China is developed by using census and population density data. Comparisons with previous studies and yearbook records indicate the reliability of our model. The modelled results are openly accessible and can be conveniently updated when more detailed census or statistics data are available.

Survey data collected over time can provide new insights on how different people respond to floods and can be used in models to study the complex coevolution of human–water systems. We present two methods to collect such data, and we compare the respective results. Risk awareness decreases only for women, while preparedness takes different trajectories depending on the damage suffered. These results support a more diverse representation of society in flood risk modelling and risk management.

This paper presents a risk assessment approach addressing the two main natural risks that affect agricultural estuarine lowlands: the scarcity of freshwater for irrigation and marine submersion. The approach is applied to an important agricultural area located in the Tagus Estuary (Portugal). Results show that the approach is appropriate to support risk owners in taking actions to mitigate the risk mainly when the possible impact of climate change in risk levels is considered.

The Alpine Drought Impact report Inventory (EDIIALPS) archives drought impact reports across the European Alpine region with an increasing number of impacts over time. The most affected sectors are agriculture and livestock farming and public water supply, for which management strategies are essential for future climate regimes. We show spatial heterogeneity and seasonal differences between the impacted sectors and between impacts triggered by soil moisture drought and hydrological drought.

Weather index insurance is an innovative program used to manage the risk associated with natural disasters, providing instantaneous financial support to the insured party. This paper proposes a methodology that exploits the power of machine learning to identify extreme events for which a payout from the insurance could be delivered. The improvements achieved using these algorithms are an encouraging step forward in the promotion and implementation of this insurance instrument.

Floods may affect critical infrastructure which provides essential services to people. We analyse the impact of floods on road networks and water supply systems, and we investigate how cascade effects propagate if interdependencies among networks are not considered. The analysis shows that if preparedness plans include information on accessibility to key sections of water supply plants, less people suffer from water shortage in case of flood. The method is tested in the city of Florence (Italy).

COVID-19 is affecting humankind in an unprecedented way, and it is changing how people perceive multiple risks. In this paper, we compare public risk perceptions in Italy and Sweden in two different phases of the ongoing pandemic. We found that people are more worried about risks related to recently experienced events. This finding is in line with the availability heuristic: individuals assess the risk associated with a given hazard based on how easily it comes to their mind.

This article assesses the thematic and composite social and health vulnerability of Bangladesh to floods. Tailored vulnerability, weighted by flood forecast and satellite inundation, can be used to predict the massive impacts of the August 2017 flood event. This approach has several advantages and practical implications, including the potential to promote targeted and coordinated disaster management and health practices.

We explored differences in the damaging process across different flood types, regions within Germany, and six flood events through a numerical model in which the groups can learn from each other. Differences were found mostly across flood types, indicating the importance of identifying them, but there is great overlap across regions and flood events, indicating either that socioeconomic or temporal information was not well represented or that they are in fact less different within our cases.

The review of flood vulnerability indices revealed that (1) temporal dynamic aspects were often disregarded, (2) coping and adaptive capacity indicators were frequently ignored, as obtaining these data demand time and effort, and (3) most studies neither applied sensitivity (90.5 %) or uncertainty analyses (96.8 %) nor validated the results (86.3 %). The study highlights the importance of addressing these gaps to produce scientifically rigorous and comparable research.

We used flow diagrams to represent the ways in which anthropogenic land use and natural hazards have affected rice production in the two mega-deltas of Vietnam. Anthropogenic developments meant to improve productivity may create negative feedbacks on rice production and quality. Natural hazards further amplify problems created by human activities. A systems-thinking approach can yield nuanced perspectives for tackling environmental challenges.

This study combines outputs from multiple models with statistical assessments of past and future water availability and demand for the S.Giustina reservoir (Province of Trento, Italy). Considering future climate change scenarios, results show high reductions for both water stored and used for hydropower production, especially in spring and summer. These results call for the need to adapt to reductions in water availability and hence on the hydroelectric production from the S.Giustina reservoir.

To improve the quantitative degree of spatial analysis of vulnerability, we construct grid-scale drought vulnerability curves of European winter wheat based on model simulation, and we discuss their spatial differences through feature points and clustering features. These vulnerability curves show zonal differences, which can be divided into five loss types, and the vulnerability increases from south to north. The results can provide guidance for regionalized risk management.

Climate change is leading to an increase in extreme events and enforces the development of adaptation strategies to face coastal risk. These strategies modify the inequalities barely considered during the decision-making process and question the resilience of these territories. On the French Atlantic coast, the study reveals that the
managed retreatstrategy seems the most sustainable over time, while the
holding the coastlinestrategy reinforces inequalities and costs for the whole society.

Earthquake early warning system (EEWS) can help reduce losses but its effectiveness depends on adequate public's perception and understanding of EEWS. This study examined the performance of the EEWS in China's Sichuan Province during the 2019 Changning Earthquake. We found a big gap existed between the EEWS's message, the public's perception of it, and their response. The study highlights the importance of gauging EEWS alert effectiveness and public participation for long-term resiliency.

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.

Local stakeholders' knowledge plays a decisional role in emergencies, supporting rescue officers in natural hazard events, coordinating and assisting, both physically and psychologically, the affected populations. Their risk perception was assessed using a questionnaire for an area in NE Romania. The results show a low preparedness and reveal substantial distinctions among stakeholders and the different threats based on their cognitive and behavioral roles in the communities.

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 city in China for making risk assessments.

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.

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.

Recurrent droughts are causing severe damages to tropical countries. We used gridded drought hazard and vulnerability data sets to map drought risk in four mesoscale rural tropical study regions in Latin America and Vietnam/Cambodia. Our risk maps clearly identified drought risk hotspots and displayed spatial and sector-wise distribution of hazard and vulnerability. As results were confirmed by local stakeholders our approach provides relevant information for drought managers in the Tropics.

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.

Focusing on Jakarta as a city with high flood risk and adaptation pressure, this study presents findings from a systematic literature review of mitigation options and the adaptation solution space to counter the city’s flood problem. Results indicate that the perceived solution space is skewed towards protection against flooding, while soft and hybrid adaptation options are less considered. This significantly influences flood risk management, influencing its effectiveness and sustainability.

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.

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.

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.

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.

Flooding in and around urban hubs can stress people. Immediate evacuation is a usual countermeasure taken at the onset of a flooding event. The flood–pedestrian simulator simulates evacuation of people prior to and during a flood event. It provides information on the spatio-temporal responses of individuals, evacuation time, and possible safe destinations. This study demonstrates the simulator when considering more realistic human body and age characteristics and responses to floodwater.
