Tsunami risk communication and management: Contemporary gaps and challenges

Very large tsunamis are associated with low probabilities of occurrence. In many parts of the world, these events have usually occurred in a distant time in the past. As a result, there is low risk perception and a lack of collective memories, making tsunami risk communication both challenging and complex. Furthermore, immense challenges lie ahead as population and risk exposure continue to increase in coastal areas. Through the last decades, tsunamis have caught coastal populations off-guard, providing evidence of lack of preparedness. Recent tsunamis, such as the Indian Ocean Tsunami in 2004, 2011 Tohoku and 2018 Palu, have shaped the way tsunami risk is perceived and acted upon. Based on lessons learned from a selection of past tsunami events, this paper aims to review the existing body of knowledge and the current challenges in tsunami risk communication, and to identify the gaps in the tsunami risk management methodologies. The important lessons provided by the past events call for strengthening community resilience and improvement in risk-informed actions and policy measures. This paper shows that research efforts related to tsunami risk communication remain fragmented. The analysis of tsunami risk together with a thorough understanding of risk communication gaps and challenges is indispensable towards developing and deploying comprehensive disaster risk reduction measures. Moving from a broad and interdisciplinary perspective, the paper suggests that probabilistic hazard and risk assessments could potentially contribute towards better science communication and improved planning and implementation of risk mitigation measures

Reliability of Build Back Better at enhancing resilience of communities

Purpose: The purpose of this study is to analyse the reliability of Build Back Better slogan in the context of post-disaster housing reconstruction in developing countries, at enhancing disaster-resilience of housing and its occupants in the long term from socio-ecological systems resilience perspective. Design/methodology/approach: A predominantly qualitative methodology and multi-disciplinary case study methodology is adopted to compare long-term outcomes of two post-disaster housing reconstruction interventions: post-2008 Bihar Kosi River floods in India and post-2010 Mentawai earthquake and tsunami in Indonesia. Findings: Out of the nine generalizable findings, two of the most significant findings include giving freedom of choice or human capabilities to the disaster survivors and sustaining capacity development during and beyond the completion of housing reconstruction. These two processes play a significant role in linking reconstruction to resilience in the long term, especially of those living at- risk and poverty. Originality/value: This paper further advances the current scholarship on overarching long-term impacts of housing reconstruction efforts, based on longitudinal and empirical studies in India and Indonesia. While these findings represent a snapshot of diverse and complex disaster experiences in the developing-world context, the comparison offers insight into how to turn the rhetoric surrounding owner-driven or built back better into long-term resilience outcomes

Leave no field behind: Future-ready skills for a risky world

The Sendai Framework, 2030 Agenda (including the SDGs) and Paris Agreements, along with 2016's Agenda for Humanity and New Urban Agenda, collectively underline the urgency for resilience building efforts. This paper probes the need for skill-sets and expertise that are ‘fit for purpose’ for advancing resilience under conditions of rapid change. It argues for systematic investment in skilled human capital as an integral component of disaster risk reduction and resilience-building, as well as in post-disaster recovery. Yet, the article draws on recent studies of higher education engagement in the disaster risk and resilience domains. These suggest persisting disciplinary fragmentation in teaching, as well as published research in these fields, along with a continuing conflation of the disaster risk discourse with emergency and disaster management. It argues that meaningful disaster risk reduction efforts require higher education to stimulate a more inclusive range of fields than currently engaged

Review and analysis of current responses to COVID-19 in Indonesia: Period of January to March 2020

The world is presently under an emergency situation because of the COVID-19 global pandemic, caused by a novel coronavirus. Indonesia is the fourth most populous country in the world and is predicted to be affected significantly over a longer time period. Our paper aims to provide detailed reporting and analyses of the present rapid responses to COVID-19 in Indonesia. We particularly highlight the progress of governments, key organisations and community responses to COVID-19 between January and March 2020. We outline the gaps and limitations in the responses, based on our rapid analysis of media contents, from government speeches and reports, social and mass media platforms. We present our recommendations toward more rapid effective, and comprehensive responses

Probabilistic Tsunami Hazard and Risk Analysis: A Review of Research Gaps

Tsunamis are unpredictable and infrequent but potentially large impact natural disasters. To prepare, mitigate and prevent losses from tsunamis, probabilistic hazard and risk analysis methods have been developed and have proved useful. However, large gaps and uncertainties still exist and many steps in the assessment methods lack information, theoretical foundation, or commonly accepted methods. Moreover, applied methods have very different levels of maturity, from already advanced probabilistic tsunami hazard analysis for earthquake sources, to less mature probabilistic risk analysis. In this review we give an overview of the current state of probabilistic tsunami hazard and risk analysis. Identifying research gaps, we offer suggestions for future research directions. An extensive literature list allows for branching into diverse aspects of this scientific approach. © Copyright © 2021 Behrens, Løvholt, Jalayer, Lorito, Salgado-Gálvez, Sørensen, Abadie, Aguirre-Ayerbe, Aniel-Quiroga, Babeyko, Baiguera, Basili, Belliazzi, Grezio, Johnson, Murphy, Paris, Rafliana, De Risi, Rossetto, Selva, Taroni, Del Zoppo, Armigliato, Bureš, Cech, Cecioni, Christodoulides, Davies, Dias, Bayraktar, González, Gritsevich, Guillas, Harbitz, Kânoǧlu, Macías, Papadopoulos, Polet, Romano, Salamon, Scala, Stepinac, Tappin, Thio, Tonini, Triantafyllou, Ulrich, Varini, Volpe and Vyhmeister
