This paper aims to develop a multi-hazard risk assessment method based on probability theory and a set of economic, social and environmental indicators, which considers the increase in hazards when they occur concurrently or consecutively.

Disaster risk assessment generally considers the impact and vulnerability of a single hazard to the affected location/object without considering the combination of multiple hazards occurring concurrently or consecutively. However, disasters are often closely related, occurring in combination or at the same time. Probability theory was used to assess multi-hazard, and a matrix method was used to assess the interaction of hazard vulnerabilities.

The results of the case study for the Mid-Central Coastal Region show that the proportions of districts at a very high class of multi-hazard, multi-vulnerabilities and multi-hazard risk are 81%, 89% and 82%, respectively. Multi-hazard risk level tends to decrease from North to South and from East to West. A total of 100% of coastal districts are at high to very high multi-hazard risk classes. The research results could assist in the development of disaster risk reduction programs towards sustainable development and support the management to reduce risks caused by multi-hazard.

The multi-risk assessment method developed in this study is based on published literature, allowing to compare quantitatively multiple risk caused by multi-hazard occurring concurrently or consecutively, in which, a relative increase in hazard and vulnerability is considered. The method includes the assessment of three components of disaster risk including multi-hazard, exposure and multi-vulnerability. Probability and Copula theories were used to assess multi-hazard, and a matrix method was used to assess the interaction intensity of multi-vulnerabilities in the system.

The overall objective of this study is envisaged to provide decision makers with actionable insights and access to multi-risk maps for the most in-danger stave churches (SCs) among the existing 28 churches at high spatial resolution to better understand, reduce and mitigate single- and multi-risk. In addition, the present contribution aims to provide decision makers with some information to face the exacerbation of the risk caused by the expected climate change.

Material and data collection started with the consultation of the available literature related to: (1) SCs' conservation status, (2) available methodologies suitable in multi-hazard approach and (3) vulnerability leading indicators to consider when dealing with the impact of natural hazards specifically on immovable cultural heritage.

The paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. The results highlight the danger at which the SCs of Røldal, in case of floods, and of Ringebu, Torpo and Øye, in case of landslide, may face and stress the urgency of increasing awareness and preparedness on these potential hazards.

The contribution for the first time aims to homogeneously collect and report all together existing spread information on architectural features, conservation status and geographical attributes for the whole group of SCs by accompanying this information with as much as possible complete 2D sections collection from existing drawings and novel 3D drawn sketches created for this contribution. Then the paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. Then it highlights the danger of floods and landslides at which the 28 SCs are subjected. Finally it reports how these risks will change under the ongoing impact of climate change.

The purpose of this paper in respect of tsunami‐affected villages in Tamil Nadu undertaken in a field trip in June 2005, and updated through online research is to first provide an overview of discrete, ongoing initiatives by different stakeholders – NGOs; Government and UNDP; Government's announcement to have a tsunami early warning system for the Indian Ocean in place by mid‐2007, paralleled by a partnership of different stakeholders to launch a pan‐India village‐info‐kiosk movement in July 2005.

The first step was to identify existing reports/programmes on disaster preparedess and mitigation, and then track the progress of the implementation of initiatives by different stakeholders. While highlighting the need for coordinated action, the author also proposed initiating a pilot project in two‐three pre‐selected village‐sites, which in turn could be upgraded to make them “Multi hazard‐ready”.

While the initiatives by different stakeholders were aimed at covering the targeted villages, as per their respective plans – there was as yet little visible attempt to privilege the tsunami‐affected villages, as was being done with their recovery efforts. Significantly, there was no mention of the proposed post tsunami Central Recovery Resource Center (CRRC) at Chennai “to meet the need for a coordinated action by all stakeholders” in the course of the discussions of early June, nor a reference to the potential for such a forum to deliberate on a coordinated Multi hazard, early warning action plan along the lines highlighted through vertical and horizontal linkages.

While the above activities were not part of a grand design – conceptualized, implemented and overseen by an over arching coordinating agency, nevertheless, together they add up to a broad based comprehensive DM resource base/infrastructure upon which hopefully an agency like the INCOIS in coordination with different stakeholders – possibly under the aegis of the Chennai CRRC – could build up its mandated tsunami – multi hazard – early warning system and its dissemination to the village‐level in TN.

The paper serves as a “one window resource guide” to provide at least the contours of a road map pointing to one of the few possible ways on how to go about a risk management plan in a coordinated and focused mode.

To provide a review of the general aspects of tsunamis and the specific aspects of the 2004 tsunami impacts on the coastal areas of India and surrounding islands.

The approach is a general discussion of the 2004 tsunami and its effects in areas in South East Asia, followed by the specific impacts in the Andaman and Nicobar Islands, including the damage to water supply and power systems, and a situation analysis of the communities, land and housing.

The impact of the 2004 tsunami highlights the vulnerability of the coastal areas and islands of India. The multi‐hazard situation existing on the sea coast of the mainland as well as in the islands of Andaman and Nicobar require a holistic multi‐hazard mitigation approach as a long term measure. The recovery programs presently in hand are being planned taking the multi‐hazard situation in view, so as to provide protection from such hazards in future.

Provides a review of the effects of the 2004 tsunami in the coastal areas and islands near India.

Urban resilience is becoming increasingly important due to increasing degree of urbanization and a combination of several factors affecting urban vulnerability. Urban resilience is also understood as a capacity of a system to prepare, respond and recover from multi-hazard threats. The purpose of multi-risk approach (MRA) is to take into consideration interdependencies between multiple risks, which can trigger a chain of natural and manmade events with different spatial and temporal scales. The purpose of this study is to understand correlation between multi-risk approach and urban resilience.

To increase urban resilience, MRA should also include multi-risk governance, which is based on understanding how existing institutional and governance structures, individual judgments and communication of risk assessment results shape decision-making processes.

This paper is based on extensive fieldwork in the test studies of Naples, Italy and Guadeloupe, France, the historical case study analysis and the stakeholders’ interviews, workshops and focus groups discussions.

Multi-risk is a relatively new field in science, only partially developed in social and geosciences. The originality of this research is in establishment of a link between MRA, including both assessment and governance, and urban resilience. In this paper, the authors take a holistic and systemic look at the MRA, including all stages of knowledge generation and decision-making. Both, knowledge generation and decision-making are reinforced by behavioural biases, different perceptions and institutional factors. Further on, the authors develop recommendations on how an MRA can contribute to urban resilience.

This paper aims to explore the involvement of various actors in the preparation of Palu City's spatial plan before the multi-hazard events of 2018. In addition, it evaluates the extent to which disaster risk reduction (DRR) is mainstreamed in the spatial plan.

The study uses qualitative methods of analysis with a risk-based planning approach and stakeholder analysis.

It is critical that DRR is mainstreamed in spatial planning from the preparation to the implementation. Disasters can take place when there is a knowledge gap in the planning process. This results in developments in disaster-prone areas and even in high-risk areas. Therefore, mainstreaming DRR into spatial planning requires national guidelines that offer planners at the local level clear and detailed guidance on what they must prepare, consider and do in a risk-based spatial planning process.

Spatial planning that does not mainstream DRR can lead to catastrophic consequences in the form of casualties and losses when multi-hazards occur.

The study provides evidence-based findings on the importance of mainstreaming DRR into spatial planning, particularly in areas prone to multi-hazards, which can be optimized through a risk-based planning approach.

It is significant to assess the societal trust toward the new advancements in multi-hazard early warnings (MHEW) with the focus on disaster risk reduction (DRR). Based on this, the purpose of this paper is to examine the extent of societal trust behavior along with the parameters such as mode of communication and institutions of issuing early warnings (EWs).

A field questionnaire survey was conducted to identify the extent of societal trust. This was conducted in ten selected Grama Niladari divisions in Sri Lanka based on a developed hazard matrix. The fuzzy logic approach was applied to examine the trust level of collected 323 responses obtained through this. The analysis was done based on the responses on mobile-based platforms in EW and the credibility level of the warnings received through different institutions.

The analyzed survey responses indicated that society has a higher extent of trust toward the EWs disseminated through mobile-based platforms. Moreover, these represent a strong positive correlation among the societal trust level and the level of importance of EW dissemination through mobile-based platforms. Further, in terms of trusted stakeholders in issuing EW alerts, Disaster Management Center, Sri Lanka Police and Media ranked the highest in the Sri Lankan context. Overall, findings were visually mapped through the causal loop diagrams (CLDs).

In enhancing the effectiveness of the existing MHEW mechanism, the policy implications could be done, based on the results obtained from this research study. These could be altered with the implementation of DRR strategies with a community focus.

The fuzzy logic approach was used in the determination of the societal decision-making on the extent of trust level. Fuzzy triangulation is mainly applied in the interpretation of the results. Further, overall parameters that determine the community trust on MHEW are represented through CLDs through system dynamics application.

This paper aims to provide a framework for building resilience to coastal hazards with reference to Asian nations at the local, intra-regional and inter-regional levels. This framework provides a roadmap that will enable higher education institutions in the region to play a significant role in educating and training new leaders for disaster risk reduction (DRR) and in working directly with local communities to implement plans.

Events such as the 2004 tsunami highlighted the transboundary nature of coastal hazard and the importance of regional cooperation. A framework for inter- and intra-regional cooperation was developed through focus groups organised with community participants in five Asian nations exposed to coastal risks: Sri Lanka, Maldives, Myanmar, Indonesia and the Philippines.

Different stakeholders assessed inter- and intra-regional cooperation at different levels as a means to provide a baseline scenario to develop a capacity-building roadmap for such cooperation. The discussions organised through structured face-to-face encounters considered cooperation at different scales: international, regional, national and local. The framework key areas were developed and included knowledge databases, data and resource sharing and exchange education programmes.

Multi-hazard early warning for more resilient coastal communities is increasingly complex in view of the discourse related to the wider economic and social environments. The research proposes a framework for inter- and intra-regional cooperation at different scales; from local to regional and to the inter-continental dimensions and even through a bottom-up approach, together with the experts’ and managing authorities’ top-down positions.

The purpose of this paper is to develop an integrated multi-risk identification procedure for World Cultural Heritage (WCH) sites exposed to seismic events, while considering characteristics of disasters from earthquakes in a multi-hazard context on one side and particular aspects of WCH (e.g. outstanding universal values and associated condition of authenticity and integrity) on the other.

An interdisciplinary review of current relevant approaches, methods, and practices is conducted through the existing literature of disaster risk management, heritage conservation, and seismology. Furthermore, a document analysis of concrete cases affected by seismic events supports concepts and the procedure.

This paper results in a methodology of identifying multi-risk of disasters induced by earthquakes. A bow-tie analysis diagram in combination with a risk identification matrix is developed for illustrating a multiple emergency scenario in identifying possible impacts of earthquakes’ primary effects, secondary hazards, and human-threats on tangible and intangible attributes of cultural properties.

The research aims to provide specialists and practitioners from multiple sectors engaged in pre-disaster risk mitigation and preparedness plan for cultural heritage with a practical risk identification tool. The proposed method, in a multiple hazard context, intends to enhance risk assessment procedure for determining more appropriate risk reduction strategies in the decision-making process.

This paper, through emphasising “earthquake disaster risk” rather than “earthquake risk”, illuminates the significance of quake-followed secondary hazards, potential human-induced hazards and human errors in the risk identification process, due to the fact that while a disaster may begin with a quake, its full scope might be triggered by a combination of the mentioned potential threats.

The development of multi-hazard risk assessment frameworks has gained momentum in the recent past. Nevertheless, the common practice with openly available risk data sets, such as the ones derived from the United Nations Office for Disaster Risk Reduction Global Risk Model, has been to assess risk individually for each peril and afterwards aggregate, when possible, the results. Although this approach is sufficient for perils that do not have any interaction between them, for the cases where such interaction exists, and losses can be assumed to occur simultaneously, there may be underestimation of losses. The paper aims to discuss these issues.

This paper summarizes a methodology to integrate simultaneous losses caused by earthquakes and tsunamis, with a peril-agnostic approach that can be expanded to other hazards. The methodology is applied in two relevant locations in Latin America, Acapulco (Mexico) and Callao (Peru), considering in each case building by building exposure databases with portfolios of different characteristics, where the results obtained with the proposed approach are compared against those obtained after the direct aggregation of individual losses.

The fully probabilistic risk assessment framework used herein is the same of the global risk model but applied at a much higher resolution level of the hazard and exposure data sets, showing its scalability characteristics and the opportunities to refine certain inputs to move forward into decision-making activities related to disaster risk management and reduction.

This paper applies for the first time the proposed methodology in a high-resolution multi-hazard risk assessment for earthquake and tsunami in two major coastal cities in Latin America.
