Tsunamis are among the most devastating and infrequent natural phenomena, capable of causing immense loss life property in coastal regions. While predicting occurrence tsunamis remains challenging, communities can take proactive steps to mitigate their impact. Local, national, intergovernmental initiatives aim provide a legal framework for strengthening community preparedness through comprehensive approach that includes measures ranging from tsunami hazard exposure assessments, generating...
This study aims to better understand coastal processes associated with extreme cyclonic events through the of changes, flooding and damage that resulted from passage a category 5 hurricane (Irma) on 6 September 2017 over islands Saint-Martin Saint-Barthélemy in Lesser Antilles. Hurricane Irma was contextualized tropical cyclone track data local weather observations collected by Météo-France, as well high-resolution numerical modelling. Field work involved accretion coasts qualitative...
Abstract. Small amplitude tsunamis have impacted the French Mediterranean shore (French Riviera) in past centuries. Some caused casualties; others only generated economic losses. While North Atlantic and tsunami warning system is being tested almost operational, no awareness preparedness measure implemented at a local scale. Evacuation to be considered along Riviera, but plan exists within communities. We show that various approaches can provide stakeholders with evacuation capacities...
Abstract. The risk of tsunami threatens the whole Caribbean coastline especially Lesser Antilles. first available models propagation estimate that travel time from closest seismic sources would only take few minutes to impact Martinique Island. Considering this threat, most effective measure is a planned and organized evacuation coastal population. This requires an efficient regional warning system, estimation maximum expected flood height, preparation population evacuate, drawing up local...
Abstract. In view of the high vulnerability small islands Lesser Antilles to cyclonic hazards, realistic very fine scale numerical simulation hurricane-induced winds is essential prevent and manage risks. The present innovative modeling aims at combining most realistically simulated strongest gusts driven by tornado-scale vortices within eyewall complex terrain effects. Weather Research Forecasting (WRF) model with nonlinear backscatter anisotropy (NBA) large eddy (LES) configuration was...
Abstract The civil security sirens are used by the authorities in a wide range of countries to signal an imminent or ongoing threat. Even if their sound level is known, it nevertheless difficult evaluate audibility across given zone, especially complex urban environments. An experimental protocol was deployed around siren installed town France, assess its perceptually and through modeling. Sound measurements during source activation were made with NoiseCapture smartphone application at...
Face à un tsunami, l’unique mesure de mise en sécurité consiste évacuer la population zone danger. Pourtant, l’une des difficultés posées pour planifier ces évacuations est variabilité fréquentation littoraux, qui fluctue spatialement et temporellement. Dans ce contexte, cette étude présente une approche associant différentes données spatialisées échelle fine (bâtiment, individus), exploitées dans Système d’information géographique (SIG), estimer le nombre personnes potentiellement évacuer,...
Since June 2022, France is equipped with cell broadcast technology which alerts individuals within a predefined area. Despite the proven effectiveness of this technology, few studies take spatial view alert at local level. Trials carried out in were assessed only on their technical success, without verifying rate reception message by official area, or gap between area and actual This study focuses trial conducted April 2023 Cannes (France). Using geo-located survey method analysis tools, we...
The civil security sirens are used by the authorities in a wide range of countries to signal an imminent or ongoing threat.Even if emitted sound level is known, it nevertheless difficult evaluate their audibility across given zone, especially complex urban environments.An experimental protocol has been deployed around siren installed city south France assess its perceptually and through modelling.This relies on (1) measurements during source activation, using NoiseCapture smartphone...
Within the study of public perception and intended declarations in case alert, an original dataset has been completed by using online questionnaire, with a short URL link included mobile alert messages, tested displayed on 19 January 2024 along French Mediterranean coast (engaging 189 municipalities 9 departments). The aim is to further know understand what people do think upon receiving Cell Broadcast alerts, that deliver attention-grabbing message directly screen phones located at-risk...
Abstract. Along the French Mediterranean coastlines, most of studies dealing with tsunamis have focused on hazards, evacuations, or effects awareness actions, as opposed to hazard perception and knowledge alert declared locally by population. To bridge this gap, in study, data collection yielded 750 responses coming from 150 people living and/or working tsunami evacuation zones five municipalities (e.g., Bandol, Bastia, Cannes, Six-Fours-les-Plages, Sanary-sur-Mer). Early findings confirmed...
Cette étude porte sur les changements côtiers et inondations suite au passage d’un ouragan de catégorie 5 (Irma) 6 septembre 2017 îles Saint-Martin Saint-Barthélemy aux Antilles. Deux missions terrain à t+2 mois t+8 deux ont permis d’analyser impacts l’ouragan Irma des côtes basses particulièrement sensibles événements météo-marins extrêmes pressions anthropiques. Le retour d’expérience a été réalisé plus touchées par l’évènement. Pour comparer interactions avec systèmes infrastructures...
The mapping of the damage caused by natural disasters is a crucial step in deciding on actions to take at international, national, and local levels. large variety representations that we have observed leads problems transfer variations analysis. In this article, propose representation, Regular Dot map (RD), compare it 4 others routinely used visualise post-disaster damage. Our comparison based user study which set participants carried out various tasks multiple datasets using visualisations....
Depuis plusieurs années, des services de cartographie sont activés à la suite d'une catastrophe afin d'offrir un premier panorama dommages. Diffusés massivement, ils se caractérisent par une diversité modes représentation cartographique, ce qui peut nuire leur compréhension. Partant constat, nous proposons solutions cartographiques optimisées différentes échelles. De plus, prenons en compte les méthodes d'acquisition, le contexte météorologique et écarts diagnostic comme paramètres cruciaux...

Cet article explore les relations entre caractéristiques territoriales et capacités de relèvement d'une petite île caribéenne, confrontée à un événement cyclonique exceptionnel : Saint-Barthélemy face IRMA (sept. 2017). L'analyse repose sur l'acquisition données récoltées in situ dans le cadre d'un retour d'expérience (RETEX) scientifique. Les l'île reposant des ressources humaines, financières logistiques ainsi qu'un faible niveau vulnérabilité, ont inscrit rapidement territoire une...
Les territoires ultra-marins français sont quasiment tous concernés par le risque tsunami. Mayotte n’échappe pas à cet aléa majeur, et aux risques induits d’importants enjeux situés sur sa bande littorale. Depuis 2018, du fait de l’activité sismo-volcanique liée l’apparition d’un nouveau volcan sous-marin (Mont Fani Maoré), plusieurs simulations tsunamis ont été produites Mayotte. Elles permis dimensionner des plans d’évacuation validés les autorités. capacités d’évacuation, mais aussi...
