Maar op 12 mei werd de rust in dit mooie toeristenoord ruw verstoord. Elf meter hoge monstergolven brachten chaos en vernieling. Het resultaat: twee vissers zijn verdwenen, pieren zijn ingestort en huizen en hotels staan onder water.<\/p>\n<\/div>\n<p>De radar van ESA's Envisat-satelliet heeft de oorzaak van de ramp vastgelegd. De radar stuurt radiosignalen naar het zeeoppervlak en vangt de echo's op. Zo kunnen wetenschappers uitrekenen hoe groot, hoe hoog en hoe snel de golven zijn. Uit de gegevens van Envisat weten we dat de golven op R\u00e9union begonnen met een zware storm in het zuiden van de Atlantische Oceaan. In de drie dagen verplaatsten de golven zich. Sommige legden vierduizend kilometer af in noordoostelijke richting, tot ze R\u00e9union overspoelden.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3508\" data-credit=\"ECMWF, NASA Quikscat\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2007\/05\/Observation_of_the_storm_winds2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2007\/05\/observation_of_the_storm_winds2\/17878182-2-eng-GB\/Observation_of_the_storm_winds.jpg\" alt=\"Observation of the storm winds\"><figcaption>Waarneming van de stormwinden<\/figcaption><\/figure>\n<p>De weerdiensten hadden wel flinke golven voorspeld maar iedereen dacht dat ze maar een paar meter hoog zouden zijn. De gegevens van Envisat laten zien dat de golven op open zee ongeveer vijf meter hoog waren en ver uit elkaar lagen. Dat betekent dat ze werden veroorzaakt door stormwind. In de buurt van de kust werden de golven afgeremd en werden ze twee keer zo hoog.<\/p>\n<p>\u201cGolfslag blijft een verrassingsfactor, die helaas dodelijke gevolgen kan hebben\u201d, aldus Bertrand Chapron van IFREMER, het Franse onderzoeksinstituut voor de exploitatie van de zee. \u201cIn de nabije toekomst verwachten wij gebruik te maken van SAR-gegevens (ruimteradar) over de golven om de aankomsttijd en intensiteit ervan te voorspellen.\u201d<\/p>","protected":false},"excerpt":{"rendered":"<p>Reunion Island in the Indian Ocean is everyone\u2019s idea of a tropical paradise.
