“…Second, Tonga is no stranger to volcanically sourced tsunamis, but such events sometimes seem to slip under the radar of tsunami researchers. In 2016 it was pointed out that the Tongan island of Lifuka was affected by a tsunami generated by an eruption of Tofua volcano, some 75 km to the west (Goff and Cain 2016). Two people were drowned when their boat capsized in the waves.…”

“…Third, there is a tendency to default to an earthquake interpretation for tsunami events with indeterminate (unknown) sources, since volcanically generated events tend to be (mis)recorded as small earthquakes. A random selection of two years of data reported in existing historical databases were re-evaluated by Goff and Cain (2016). Re-evaluation suggested that earthquakes sources for Pacific tsunamis should be reduced from between 65-70% to between 20-30%.…”

January 2022 witnessed the violent eruption of Hunga Tonga–Hunga Haʻapai submarine volcano in the South Pacific. With a volcanic explosivity index possibly equivalent to VEI 5, this represents the largest seaborne eruption for nearly one and a half centuries since Indonesia’s cataclysmic explosion of Krakatau in AD 1883. The Tongan eruption remarkably produced ocean-wide tsunamis, never documented before in the Pacific instrumental record. Volcanically generated tsunamis have been referred to as a ‘blind spot’ in our understanding of tsunami hazards, particularly in the Pacific Ocean. This event therefore presents a unique opportunity for investigating the multiple processes contributing to volcanic tsunamigenesis. It is argued that, although challenges exist, integrating theoretical, observational, field and modelling techniques offers the best approach to improving volcanic tsunami hazard assessment across Oceania.

Big data and disaster management: a systematic review and agenda for future research

2017

View full text Add to dashboard Cite

The era of big data and analytics is opening up new possibilities for disaster management (DM). Due to its ability to visualize, analyze and predict disasters, big data is changing the humanitarian operations and crisis management dramatically. Yet, the relevant literature is diverse and fragmented, which calls for its review in order to ascertain its development. A number of publications have dealt with the subject of big data and its applications for minimizing disasters. Based on a systematic literature review, this study examines big data in DM to present main contributions, gaps, challenges and future research agenda. The study presents the findings in terms of yearly distribution, main journals, and most cited papers. The findings also show a classification of publications, an analysis of the trends and the impact of published research in the DM context. Overall the study contributes to a better understanding of the importance of big data in disaster management.
