To provide data on the tsunami hazard of the Mediterranean region, to outline the Maltese Islands specific tsunami risks.
Abstract
Purpose
To provide data on the tsunami hazard of the Mediterranean region, to outline the Maltese Islands specific tsunami risks.
Design/methodology/approach
The physics of tsunami and the tsunami magnitude scales are first introduced. The Mediterranean tsunami characteristics are introduced by reference to sources (1962‐2003). Following this the Mediterranean tsunami vulnerability assessment is undertaken. This then narrows down to assessing the Maltese tsunami hazards with reference to various newspaper articles, with finally a risk assessment for Malta tsunami exposure calculated.
Findings
Considering the high loss of life occurring in the Indian Ocean catastrophic tsunami, tsunami awareness hazards are to be kept ongoing whilst Malta should form part of an expected European Tsunami Warning System.
Practical implications
Planning is to consider various options available including tsunami barriers, evacuation paths, buildings with vertical evacuation facilities. It would be more prudent to work with nature by moving all inessential structures further into the interior and to protect the shoreline with suitable vegetation.
Originality/value
Creates a Mediterranean/Maltese awareness to tsunami hazards/risks in a highly developed tourist region.

Abstract
Purpose
The December 2004 tsunami was one of the largest natural disasters in the recent history of Southeast Asia. This paper aims to unfold the experiences of tsunami victims in a highly affected region of Thailand and to examine their post‐tsunami health.
Design/methodology/approach
Ethnographic fieldwork was carried out in Khao Lak and Thi Muang, two major tsunami affected towns in southern Thailand in May 2007. Detailed informal interviews and participant observation were employed to obtain narratives of tsunami victims.
Findings
The research reveals that the health of the tsunami survivors has deteriorated, and that they are still experiencing psychological suffering two and a half years after the tsunami.
Research limitations/implications
The long‐term health condition and care should be prioritized in post‐disaster management.
Originality/value
This paper argues that inner healing, which is not usually considered a priority in the development discourse, is essential to relieve the mental pain of tsunami survivors and to aid their post‐disaster recovery. It highlights that culturally pertinent inner healing is invaluable.

Abstract
Purpose
This study aims to identify the gaps in current policy and propose a viable framework for policy improvement regarding people-centered tsunami early warning chain in Padang City. The objectives are: to describe the gaps and flaws in the current policy regarding local tsunami early warning chain, to identify potential actors to be involved in the tsunami early warning chain and to assess the roles and capacity of actors, and their potential for involvement in early warning.
Design/methodology/approach
This study is an exploratory study using social network analysis (SNA) on regulations and other legal documents, and primary data sources from a focus group discussion and semi-structured interviews.
Findings
The study found that the existed regulation lacks extension nodes to relay warnings to the populations at risk, often referred to as “the last mile.” Moreover, receiving warning information from both formal and informal sources is important to mobilize people evacuation more effectively during an emergency. The study found that mosque communities and disaster preparedness leaders are the potential actors who should be involved in the local early warning chain.
Practical implications
The research findings were presented as a recommendation to Padang City Government and have been legalized as the new tsunami early warning chain procedure in the Padang City Mayor Regulation 19/2018.
Originality/value
This research investigated local tsunami early warning dissemination in Padang City using SNA. The study demonstrates a close collaboration between researchers, practitioners and the community.

Abstract
Purpose
The paper aims to discuss the findings of a humanitarian logistics manager field study on response activity concerning the 2004 tsunami disaster in terms of what should have occurred and to present a comprehensive hindsight‐analysis case for a model placing natural disaster response activity clearly within the context of local‐nation‐led, holistic and inclusive natural disaster planning.
Design/methodology/approach
The qualitative testing of a conceptual framework of natural‐disaster response requirements through interviews with tsunami‐response logistics managers, the analysis of the findings in the light of tsunami‐hindsight “effective disaster management” themes of recent academic literature and multi‐agency reports and the development of the holistic, inclusive planning model.
Findings
That natural disaster response activity needs to be viewed holistically in the context of a disaster management planning continuum that ideally starts well before the response action is required and of which locally‐led inclusiveness is a crucial component.
Research limitations/implications
The model needs to be tested for its applicability as a planning instrument and guide for response activity in the context of future natural disasters.
Practical implications
The holistic/inclusive planning model has been developed to guide natural disaster planners as well as add to academic discourse in the search for natural disaster management solutions.
Originality/value
The study is original with its field‐based qualitative research foundation and reflective hindsight analysis.

Abstract
Purpose
Public open spaces (POS) in cities are often measured as a strength to enhance cities’ sustainability with a contribution to the three pillars: economic, social and environmental. Nevertheless, the importance of POS for disaster resilience is less recognised and remains under-rehearsed in the urban planning context. Within this context, this research paper aims to investigate the methods and approaches of using POS to enhance the coastal cities’ resilience to tsunamis through planning and designing interventions.
Design/methodology/approach
This study used the grounded theory as the research strategy. Accordingly, data collection involved 72 unstructured interviews covering a wide variety of participants related to the field of study including tsunami-affected communities, disaster resilience experts, urban planners, sociologists and coastal planners, in the context of Sri Lanka. The grounded theory coding procedure is used to analyse the data that includes transcripts, notes, maps and documents.
Findings
The analysis reveals that there is a significant potential to use POS to enhance the coastal cities’ resilience to tsunamis as an emergency evacuation directing point, as a primary place for emergency rescue, as an agent for temporary sheltering, as a facilitator for tsunami disaster mitigation and as a mediator to provide tsunami awareness. Finally, the findings propose five guiding factors for planning POS to enhance coastal cities’ disaster resilience to Tsunamis.
Originality/value
This paper introduces an innovative and unique approach for future urban planners and design professionals, to plan and design POS with a new direction towards disaster resilience while ensuring sustainability.

Abstract
Purpose
This paper seeks to provide a timely consideration of how regional governments in Asia and other national governments around the world collect, manage, and share critical geo‐technical information in what is becoming an increasingly global community.
Design/methodology/approach
The paper addresses the socio‐technical perspective of government information systems and management, and draws on the collection and analysis of several public reports, media articles, and expert opinions published in the aftermath of the Asian tsunami of 26 December 2004.
Findings
On the basis of the published material, the paper observes how critical early warning information was handled by government authorities in the hours before the tsunami wave strike, discusses the availability of technological solutions that can provide earthquake and tsunami warning information, and poses that government bureaucracies and human relations form the weakest link in the information chain.
Research limitations/implications
The paper concludes with a potential research agenda for government warning information systems and management.
Practical implications
The type of early warning information system that might be created to avoid another loss of life, suggested improvements to inter‐government information sharing and communications, and the emerging requirement for earthquake and tsunami information dissemination and education in lesser developed countries are also discussed.
Originality/value
The research enabled the examination of weaknesses in critical information sharing between governments and members of the international community, and highlights the issue of strong human relationships as a key to preventing the loss of life and better managing disasters.

Abstract
Purpose
This paper aims to identify the specific parameters in developing a framework to assess the structural vulnerability of hospital buildings in Sri Lanka against tsunami. Along with that, the adaptability and suitability of the existing global frameworks in the Sri Lankan context are to be assessed.
Design/methodology/approach
In this study, Papathoma tsunami vulnerability assessment (PTVA)-4 model was used as the base in developing the abovementioned framework. Its adaptability and suitability in assessing hospital buildings in the country were considered under the case studies conducted in six selected hospitals in the Southern coastal belt of Sri Lanka. Under these case studies, data collection was done using the Rapid Visual Screening method where assessments were carried out through visual observations. The collected data were analyzed according to the aforementioned model for its suitability in evaluating the structural vulnerability of hospitals in Sri Lanka, against tsunami hazard.
Findings
From these case studies, it was identified that the use of the PTVA-4 model alone was insufficient to assess the structural vulnerability of the hospital buildings against the tsunami. Therefore, the model must be further improved with more relevant assessing attributes related to hospitals, suitable for the Sri Lankan context.
Originality/value
This paper identifies the specific structural assessment parameters required in assessing hospitals in the coastal belt of Sri Lanka, considering tsunami as the main hazard condition.

Abstract
Purpose
This paper aims to analyse as to how the benefits to Tsunami affected small industry were misplaced and carried wrong priorities. Besides the support provided was insufficient for an effective recovery. There existed many governance‐related problems. Overall recovery was at a low figure of 64.8 percent. The occurrence of the natural disaster of this high magnitude leaves a trail of lessons to be learnt by both the government agencies and also the donor community. There was no shortage of either the funds or the commodities, but it was sadly the governance and the sensitivity to the suffering of the people.
Design/methodology/approach
The study employed the proven methodologies of a survey of available literature, web sites, and publications to obtain secondary data and information on industry especially the micro and SMEs in areas of disaster damage occurred because of Tsunami. The second methodology of research is in areas of collection of data on industry at national level and categorization for selection of sample size. Interviews formed an important source of information. Interviews were conducted with relevant stakeholders conducting various rehabilitation and re‐establishment programmes.
Findings
Micro and SMEs are important for economic development of Sri Lanka. These carry a strategic importance to generate employment. As such rehabilitation of industry affected by Tsunami is vital. Tsunami could have been used by the government, development agencies and donors as opportunity for rebuilding on modern lines. The main damage was caused to the plant and machinery. A right expenditure should have been in the direction of procurement of tools, equipment and machinery for the affected units. Unfortunately the help could not be organized to reach the right industry, in right quantity, and right way. Surprisingly, it was not because of shortage of funds.
Originality/value
The present case leaves lessons for development agencies, government departments and welfare associations. No such extensive study seems to have carried out.

The paper aims to study the effects of the tsunami that affected Banda Aceh in 2004.
Abstract
Purpose
The paper aims to study the effects of the tsunami that affected Banda Aceh in 2004.
Design/methodology/approach
During a survey by Japanese researchers in Banda Aceh and surrounding areas in Indonesia after the great Sumatra earthquake, questionnaires were distributed to the people affected by the earthquake and tsunami. The purpose of the questionnaires was to collect information of what happened and what were expected by the affected people to be safe against future earthquake and tsunami. The questionnaires consisted of questions asking their experience during and after the earthquake and tsunami.
Findings
One important result of the questionnaires shows that even if people had started running away just after the big earthquake, the percentage of expected survivors would have been less than 100 percent.
Originality/value
The paper shows that education, socialization (software) and escape structures, warning system, wave resisting structures (hardware) are important factors for people to be safer against future earthquake and tsunami attacks.

– The purpose of this paper is to assess the vulnerability of the Kesennuma area in Japan to a tsunami disaster and to map the area of inundation.
Abstract
Purpose
The purpose of this paper is to assess the vulnerability of the Kesennuma area in Japan to a tsunami disaster and to map the area of inundation.
Design/methodology/approach
Digital elevation model (DEM) data and ALOS image were used to create maps of the parameters of this study area: elevation, slope, coastal proximity, river, and land use. An analytical hierarchy process was used to assign weights to each parameter and a spatial multi-criteria analysis was applied through cell-based modelling for vulnerability mapping.
Findings
The vulnerability map shows that 17.679 km2 of the area could be inundated by a tsunami. High vulnerability areas were mostly found in coastal areas with a sloping coast and a cape area. A low elevation and the presence of rivers or water channels are factors that increase the impact of tsunamis. Inundation areas were predicted to spread in areas identified as having either high vulnerability or slightly high vulnerability.
Research limitations/implications
Because of the limited geospatial data, the authors encourage further studies using DEM data with a high spatial resolution.
Practical implications
The results of this research can be used as basic information for disaster mitigation and urban planning in coastal areas.
Originality/value
This research creates a new approach for assessing which areas could be inundated by tsunamis, based on the vulnerability map generated through remote sensing and spatial multi-criteria analysis. Moreover, the parameters used are very close to those of actual inundation maps.
