Abstract Sixteen years have passed since the last global volcanic event and more than 25 a catastrophe that killed tens of thousands. In this time, volcanology has seen major advances in understanding, modelling predicting hazards and, recently, an interest techniques for reducing mitigating risk. This paper provides synthesis literature relating to aspect, specifically communication risk, with view highlighting areas future research into encouraging risk-reducing behaviour. Evidence...
While children are one of the groups at risk in disasters, they can also take an active part disaster management, provided that opportunity is given. This research examined effect experience, education, country, and city socioeconomic status on children's perceived preparedness with a survey 1335 between 11 14 years old, Nepal Turkey. The used questionnaires pictorial representation illness self measure (PRISM) tool. Results showed (1) perceptions were line their country-specific objective...
One of the most dangerous challenges to settlements in UK comes from flooding. Currently, there is extensive map coverage flood hazards zones UK; however, it increasingly recognised that risk associated with natural cannot be reduced solely by focussing on hazard. There also an urgent need for methods evaluating and mapping vulnerability detail. Despite its significance, conventional assessment methodologies often underestimate likely levels areas prone hazards, yet degree within a community...
ABSTRACT Climatic and topographic factors are critical for influencing vegetation cover, especially in mountainous areas. This study investigates dynamics the South‐Western (SW) North‐Eastern (NE) zones of Kilimanjaro over past two decades. We used Moderate Resolution Imaging Spectroradiometer (MODIS) data, focusing on Normalised Differential Vegetation Index (NDVI) trends their relationship with climatic factors. The NDVI dataset 2000–2022 was combined Digital Elevation Model (DEM) data...
Abstract A small bifurcating gully head displaying shallow pipe development was surveyed to explore how far three‐dimensional patterns of geochemistry and sediment size can be related hydraulic gradients in the local marl bedrock (Almería, SE Spain). The crust, sub‐crust parent materials were sampled every 20 cm across a 2 m by 3 grid, then analysed for dispersive granulometric characteristics. Spatial sodium adsoption ratio (SAR) each layer plotted separately. In‐situ material at depths...
Abstract In 2017, hurricane Maria caused unprecedented damage and fatalities on the Caribbean island of Dominica. order to ‘build back better’ learn from processes causing damage, it is important quickly document, evaluate map changes, both in Dominica other high-risk countries. This paper presents an innovative relatively low-cost rapid workflow for accurately quantifying geomorphological changes aftermath a natural disaster. We used unmanned aerial vehicle (UAV) surveys collect imagery 44...
Digital information technologies, such as the Internet, mobile phones and social media, provide vast amounts of data for decision-making resource management. However, access to these well their associated software training materials, is not evenly distributed: since 1990s there has been concern about a "Digital Divide" between data-rich data-poor. We present an innovative metric evaluating international variations in digital data: Data Poverty Index (DPI). The DPI based on Internet speeds,...
Dominica, along with several other Caribbean islands, was severely damaged by category-5 Hurricane Maria in September 2017. The hurricane left 68 people dead or missing, marking as the worst natural catastrophe to hit this small island nation. Here, we report results of our coastal runup field survey February 2018 and tide gauge sea-level data analysis. Analysis records shows that duration Maria's surge varied between 2.1 2.6 days region at Marigot, Dominica. amplitude 75 cm which indicates...
Abstract A 10‐year study of groundwater‐dominated headwater streams in the chalklands southern England has highlighted major influence that stream flow on composition in‐channel macrophyte communities. Macrophytes supply much physical structure within these channels, as well providing habitats for a rich assemblage higher life forms, some them specialized and rare. The overall however, is modulated by many environmental factors operating at diverse spatial scales. Data describing relevant...
Among several natural and anthropogenic conditioning factors that control slope instability, heavy rainfall is a key factor in terms of triggering landslide events. In the Mediterranean region, Crete suffers frequent occurrence rainstorms act as mechanism for landslides. The island from occurrences rainstorms, which often trigger Therefore, spatial temporal study recent storm/landslide events projection potential future crucial long-term sustainable land use landscapes with similar...
Abstract The aim of this study was to examine the effects a disaster education intervention on children's risk perception and preparedness. It also sought advance longitudinal studies, during an 18‐month time period, preparedness by using quasi‐experimental methodology in child‐centred research. This used research design measure children. These were examined Van Kocaeli provinces Türkiye with sample 720 school Experimental control groups randomly allocated, controlling for age, grade...
Various physical attributes of the Earth's surface are factors that influence local topography and indirectly human behaviour in terms habitation locations. The determination geomorphological setting plays an important role archaeological landscape research. Several landform types can be distinguished by characteristic geomorphic portray surrounding a settlement its ability to sustain population. Geomorphometric information, derived from digital elevation models (DEMs), such as ASTER Global...
This article presents a low-cost insurance system developed for small-hold farms in disaster-prone regions, primarily using free Earth Observation (EO) data and Free Open Source Software (FOSS) – collectively termed sustainable geoinformatics - with proprietary mobile phone app that enables verification. The study examined 30 Risaralda department, Colombia. A Digital Elevation Model (12.5m pixels) from the ALOS PALSAR satellite sensor was used Geographical Information System (GIS) to map...
The disaster management applications of geographical information systems and remote sensing are examined relative to the cycle, in pre-disaster, crisis post-disaster contexts. We focus on uses limitations free or low-cost data software. A wide range geospatial datasets currently freely available, from digital elevation models (DEMs) thematic maps, multispectral satellite imagery virtual globes, such as Bing Maps. Maps hazardous terrain vulnerable features can be derived sets shuttle radar...
This study was conducted to determine the suitability of near-infrared (NIR) spectroscopy for subsurface monitoring crude oil contaminants in different soil types under moisture conditions. Calibration tests, carried out both wet and dry soils, with contents 5–30% indicate an inverse relationship between spectra content R2 values ≥0.98 mixtures. A derived index termed "Oil Index" generated by calculating a spectral ratio main peak NIR region spectrally inactive part spectrum within visible...
