Impacts of the storm Hercules in Portugal

Abstract

João corte-real 3 abstract -the aim of this study is to analyse the impacts of the Hercules storm in Portugal. the storm occurred from January 5 th to 7 th , 2014. a brief characterization of the storm was conducted and the witnesses' accounts were compiled, complemented with field survey before and after the storm. the results show that this event had origin in a strong system of low pressure that hit Portugal. the system triggered strong sea waves with long periods, run-ups between 6 to 9 m, and inundation depths mostly under 1 m. the effects on the Portuguese coastline showed some weaknesses in the spatial planning management: (i) the fact that a wave train res tricted to the beaches, front streets, ports and marinas caused significant damage; (ii) some people ignored the emergency management authorities, putting themselves in a risk situation. Keywords:Hercules storm, media, witnesses' accounts, field survey, risk awareness.resumo -iMpacto da teMpeStade Hercules, eM portugal. neste estudo, analisam--se os impactos da tempestade Hércules, que atingiu Portugal entre os dias 5 e 7 de Janeiro de 2014. Caracteriza-se brevemente a tempestade, e apresentam-se os relatos das testemunhas e os resultados do trabalho de campo anterior e posterior à tempestade. este evento teve origem num forte sistema depressionário que provocou forte agitação marítima, ondas de longo período, run-ups de 6 a 9 m, com profundidades de inundação em geral inferiores a 1m. Os efeitos no litoral português ilustram algumas fraquezas no ordenamento e gestão do território: (i) o facto de um conjunto de ondas, mesmo restringidas às praias, marginais, portos e marinas, ter cau sado elevados prejuízos materiais; (ii) a circunstância de os avisos das autoridades da gestão da emergência terem sido ignorados por indivíduos, que assim se colocaram em situação de risco. , XLiX, 98, 2014, pp. 197-220 198 A. Santos, S. Mendes and J. Corte-Real résumé -iMpactS de la teMpête Hercule au portugal. La tempête "Hercule" a touché le Portugal du 5 au 7 janvier 2014. Pour analyser ses conséquences, on l'a sommairement caractérisée, on a recueilli divers témoignages et on a observé le terrain, avant et après la tempête. Ce système dépressionnaire accentué a provoqué une forte agitation maritime, avec des vagues de longue période et de 6 à 9 m d'amplitude. Les dégâts enregistrés révèlent certaines faiblesses de gestion de la part des autorités : i) il est anormal que des vagues n'ayant touché qu'une étroite bande littorale aient provoqué de tels dégâts matériels; ii) Les avis de danger émis par l'organisme chargé de gérer les situations périlleuses ont été ignorées par certaines personnes, qui ont ainsi couru des risques.

Submarine platform development by erosion of a Surtseyan cone at Capelinhos, Faial Island, Azores

“…‘Christina’ (also called storm ‘Hercules’) was the latest extreme cyclone to approach the Azores archipelago (on 5–7 January 2014). The waves generated reached 9–11 m (Melo et al ., ) and significantly damaged coastal structures (Santos et al ., ). Faial's mean annual tidal range is only ~0.9 m (Quartau et al ., ), which corresponds to a microtidal regime (Short, ).…”

Genesis and morphological evolution of coastal talus-platforms (fajãs) with lagoons: The case study of the newly-formed Fajã dos Milagres (Corvo Island, Azores)

“…Corvo. This storm, over the Atlantic Ocean, was characterized by an unusually large fetch that led to long period waves (~10 mins; Santos et al, 2014). It approached from NW and, at Corvo, attained offshore wave heights of 9-11 m. During this event, storm waves were responsible for, simultaneously, eroding the seaward margin of the fajã, and pushing the sedimentary deposit landwards, causing the disappearance of any residual lagoon.…”
