“…In a volcanic island with seismic activity like La Palma, locals should be continuously prepared by public agents through their communications. By stablishing that behavioral responses on crisis are influenced by the preparedness of the publics, Spero et al, (2022) propose virtual reality to educate the general public on the scale of risks provoked by natural disasters. On the same line, Lim et al, (2022) suggest that governments need to embody social norm messaging to enhance disaster risk preparedness and mitigation behaviors in the pre-crisis stage.…”

“…During the event of a natural disaster, government's communications will determine how publics perceive the crisis and how prepare they are to deal with it (W. Liu et al, 2018). On this line, the work done by the public authorities during the pre-crisis stage becomes key (Fearnley et al, 2018;Spero et al, 2022). For example, if a local authority is present and active on Twitter prior to the crisis it will help publics to become more familiar with that tool and, therefore, it will be easier for the institution to communicate through it during a crisis (Eriksson, 2018;Spence et al, 2017).…”

This study examines and evaluates how the government communicated the volcanic eruption that occurred in La Palma (Spain) in 2021. For that purpose, SCCT and the SMCC models were used to perform a content analysis of the online communication approach followed on Twitter by Cabildo de La Palma (@CabLaPalma), 112 Canarias (@112canarias), and the Spanish Home Office (@interiorgob). Findings suggest that these three institutions aligned their communications by using complementary strategies, message framings and styles to successfully handle the crisis. However, this study also highlights areas of improvement in the approaches taken by these three public entities.

“…In fact, modelling of a virtual scene is a very important component of the application of VR technology in geohazard studies and education [67]. Thus, digital 3D models were used to reproduce landscapes vulnerable to geohazards such as landsliding [70][71][72], volcanic eruptions [7,8], and flooding [73,74], but also subject to technological hazards such as dam failing [75].…”

Virtual reality is a technological development that, among others, has revolutionized Earth sciences. Its advantages include an opportunity to examine places otherwise difficult or impossible to access and it may also become an important component of education, fostering a better understanding of processes and landforms, geohazard awareness, and an appreciation of geoheritage. This paper reports on the GeoVT project, which aims to create a platform to build and disseminate Virtual Field Trips (VFTs) focused on geomorphology, natural hazards associated with geomorphological processes, and geoheritage sites. To put the GeoVT project in context, an overview of applications of VR in geosciences is provided. This paper subsequently proceeds with a presentation of the project and the GeoVT Authoring application, which is an innovative platform designed to help teachers and students, followed by brief presentations of a number of VFTs developed within the project. They address themes such as fluvial landforms and valley development, coastal landforms, evidence of past glaciation, coastal erosion, wildfire effects, mud volcanoes, and landslides.

“…Such dataset has been used in the dam breach study of Psomiadis et al (2021) and in dam removal studies (Evans et al, 2022). Furthermore, this might be a useful dataset in the creation of a 3D virtual environment for communicating the dam breaks in the future, as discussed in Spero et al (2022). However, this dataset is costly compared to global datasets and requires special technology and skills to acquire the data.…”

Catastrophic failure of dam structures has often led to severe consequences. The colossal wave receding at a higher velocity from the sudden failure of the dams may obliterate the downstream areas causing loss of lives and property damage. Thus, proper mitigation measures and contingency plans must be formulated beforehand to minimize the impact of such disasters. Consequently, there has been a strong tendency to study dam breach flood modeling using different approaches for both hypothetical dam breach scenarios and real incidents. The technology used for dam breach studies is advancing and a comprehensive review of the existing methodologies would help the modelers in their model development. This paper reviews the state‐of‐the‐art methodologies utilized in studies to propagate the dam break flood wave. Furthermore this guides the selection of methods best suited considering the project‐specific requirements and the complexity of project to simulate the risk to the vulnerable areas generated from the dam break flood flow. Different terrain datasets, mesh generation techniques and calibration techniques have been adapted and adhered to improve computational accuracy, stability and efficiency in modeling dam break floods. The use of high‐resolution global and site‐specific datasets, subgrid models, the choice of roughness coefficients and high‐resolution time steps have to be investigated thoroughly in these models. The paper reviews the existing methodologies with the strengths and limitations facilitating the future dam breach modelers to select the suitable approach in dam break flood wave modeling.This article is categorized under: Engineering Water > Sustainable Engineering of Water Science of Water > Water Extremes Water and Life > Conservation, Management, and Awareness
