Onshore lithostratigraphic surveys were used to validate tsunami inundation models in Verde Lago (Algarve, Portugal). To numerical modelling, filed data was gathered including: sediment samples collected eight trenches and three cores retrieved within the Late Holocene stratigraphic sequence. Furthermore, textural analysis age-estimation of main units obtained. Five sequential identified defined different trenches.A tsunami-related depositional unit described medium-sand dominated It...
ABSTRACT The Hunga Tonga Ha’apai eruption of January 15th, 2022, was a rare geological event, resulting in atmospheric pressure waves being recorded around the world, along with sea level fluctuations. This research aims to analyze tsunami and observed Caribbean adjacent regions, which were generated by this eruption. These kinds perturbations are uncommon have not been seen many occurrences, let alone global implications. Modern instrumentation including both barometers stations, provided...
Every year, in Rio de Janeiro State, dozens of people die and thousands are affected by natural disasters related to extreme weather events, especially floods landslides. In last years (2010 2011) more than thousand died Angra dos Reis, the Metropolitan Region City mountainous region State. The Megadesastre event occured between days 11st 12nd January 2011, affecting seven cities this region, Nova Friburgo, Teresópolis Petrópolis, killing 947 people. It is considered one biggest events mass...
The aim of this work is to identify and characterize microtextural signatures in silica\glass grains (used as analogous quartz) that are produced during aqueous transport at different flow velocities, with variable sediment concentrations, distances, time intervals.To achieve this, an open-channel experiment was conducted a mixture sand microspheres varying conditions -velocity (from 0.67 1.4 m/s), duration (1 or 10 minutes), distance (0 2.5 m) concentration (60% 80%).Experimental were used...
Abstract The precise location of the seismic source 1755 CE Great Lisbon earthquake is still uncertain. aim this work to use an onland sedimentary record in southern Portugal test and validate sources for earthquake. To achieve this, tsunami deposit thicknesses from over 150 cores collected at Salgados were compared results a sediment transport model (Delft3D‐FLOW) that simulates propagation, inundation, erosion, deposition. Five different hypothetical modeled with varying bed roughness...
Os movimentos de massa são um dos mais atuantes e impactantes fenômenos relacionados aos desastres. No Brasil, agravados por uma série fatores como a presença maciços montanhosos associados condições climáticas favoráveis, tal ocorre na Região Serrana do Estado Rio Janeiro. Neste sentido, o presente trabalho tem objetivo analisar grau influência condicionantes ocorrência Bacia Paquequer (Teresópolis, RJ) gerando mapa suscetibilidade esses eventos partir da análise multicritério AHP Média...
The Córrego do Principe (1,197 ha) watershed located at the mountainous range “Região Serrana” of state Rio de Janeiro was seriously affected by a debris flow that took place on January 12th, 2011. event triggered an extreme rainfall resulted in major disaster causing destruction and deaths. Field observations together with Quickbird satellite images analysis (0.6 m resolution August/2006 1:8,000 aerial pictures May/2011) identified classified damages affecting buildings associated...
O estudo da distribuição de chuva no Brasil é importante tanto para a economia quanto redução desastres naturais. Os eventos chuvas intensas que causam secas inundações geram perdas e danos sobretudo população mais carente. Com isso, o objetivo deste artigo analisar espaço temporal das na região Baixada Fluminense, Rio Janeiro, período entre 2003 2017. Para foram utilizados seis postos pluviométricos estações meteorológicas, distribuídas ao longo região. A anual acumulada Fluminense 1830 mm,...
Nos últimos anos, temos acompanhado no Brasil e mundo grandes desastres que exigiram uma maior capacidade de resposta. Este fato já foi apontado até mesmo nas Conferências das Nações Unidas sobre Redução Risco Desastres. A contribuição responsabilidade o geocientista tem na identificação avaliação perigos classificação áreas risco - ações comuns à Gestão Riscos são relativamente mais conhecidas discutidas, tanto meio acadêmico quanto técnico, porém, não é ainda tão explorado papel,...
The Hunga Tonga-Hunga/Hunga-Ha'apai eruption on January 15, 2022 sent off a plume of ash material up to the stratosphere and triggered meteotsunami barometric pressure pulse that rippled through atmosphere oceans all around world. nature volcanic event its global impacts oceans, atmosphere, lithosphere cryosphere are matter debate. Here we present first overview time travel sound atmospheric wave Antarctic continent based in situ measurements, which represented unique observed polar ice...
Eventos extremos de chuva e cidades não planejadas reforçam a importância do mapeamento das inundações urbanas. Por outro lado, dados espaciais meteorológicos disponibilizados por agências governamentais, são compatíveis com o estudo assim criam um cenário escasso efetivamente medidos. Dessa forma, presente trabalho objetiva mapear perigo para bacia hidrográfica urbana (Rio Botas, Nova Iguaçu, Rio Janeiro) poucos disponíveis. O é realizado meio modelos hidrológico hidrodinâmico. Como...
Atualmente, os conflitos para a inserção da água mineral na gestão dos recursos hídricos decorrem diferentes momentos história política brasileira. A legislação de (Código Águas Minerais 1945 e Código Mineração 1967) originou-se em governos com políticas centralizadoras, enquanto que (Constituição Federal, 1988 Política Nacional Recursos Hídricos, 1997) possui um caráter democrático, descentralizador multiparticipativo. Este estudo baseou-se numa análise geral registros históricos evolução...

In this paper we present the results of integration various High Resolution Airborne Magnetic (HRAM) surveys that have been conducted by FUGRO-Lasa-Geomag in Santos Basin since 1998. These greatly differ from old airborne and marine magnetic data were acquired past. The high spatial resolution accuracy measurements amplitude positioning anomalies characterize data. We a variety maps obtained through use Fourier filtering techniques discuss their value to magneto-structural imaging...
Spotted fever rickettsiosis is a zoonosis transmitted by ticks, having varied clinical course that can lead to death if not managed properly. In Brazil it more commonly observed in the Southeast, being an emerging public health problem. Hazard mapping models are common different areas of knowledge, including health, as way inferring reality and seeking reduce or prevent damage. The aim this study offer spatial heuristic methodology for assessing potential risk transmission spotted Rio de...
