Les baleines peuvent-elles prévoir les tsunamis ?

Les baleines peuvent-elles prévoir les tsunamis ?
Les infrasons produits par les tremblements de terre sous-marins seraient captés par les baleines

Un photographe britannique a interpellé la communauté scientifique pour savoir si oui ou non les baleines peuvent sentir les tsunamis arriver. Il dit en effet avoir observé un changement du comportement des cétacés face aux tremblements de terre sous-marins.

Ce n’est pas la première fois que la question de la capacité de certains animaux à « sentir » les tremblements de terre est soulevée. Il est en effet déjà communément admiss que certains animaux comme les éléphants peuvent entendre les infrasons, produits par les tremblements de terre, les éruptions volcaniques et les avalanches. De fait, observer leurs réactions pourrait s’avérer une bonne mise en garde contre les catastrophes à venir.

Le photographe Andrew Sutton a constaté, quelques minutes avant le tremblement de terre survenu au large du Sri Lanka mercredi dernier, que tous les cétacés, du dauphin à la baleine, avaient auparavant quitté les lieux. Des pays comme le Japon et la Nouvelle-Zélande ont quant à eux pu voir s’échouer sur leurs côtes des dizaines d’animaux marins.

Les infrasons produits par les tremblements de terre se propagent beaucoup plus vite dans l’eau, c’est pourquoi les animaux possédant la capacité de les détecter peuvent, en tout cas sur le papier, fuir la zone de la catastrophe. Des cas similaires ont par ailleurs déjà été étudiés, notamment en Asie, où un troupeau d’éléphants domestiqué avait décampé peu de temps avant le tsunami de décembre 2004, et aux Etats-Unis, où un tremblement de terre de magnitude 5,1 sur l’échelle de Richter avait été détecté longtemps à l’avance par divers animaux domestiques. Dans le cas des pachydermes, qui étaient pourtant équipés de bagues émettrices, les chercheurs n’ont cependant pas réussi à déterminer où ils étaient partis, le contact ayant été perdu 8 heures avant l’arrivée du tsunami pour n’être récupéré qu’une heure plus tard.

M. Sutton a pour sa part assuré que ni lui ni ses condisciples, qui se trouvaient sur un bateau, ne se doutaient de l’imminence d’un tremblement de terre. Ils ont en revanche pu assister pendant quelques minutes à un exode de cétacés fuyant l’endroit dans lequel ils se trouvaient. « C’est assez », dirait la baleine en allant se réfugier vers des eaux plus calmes.

     C’est assez incroyable que l’on redécouvre les vertus attribués aux animaux  que l’on pourrait mieux étudier au lieu de les massacrer!
    Notamment les japs qui ont le culot de dire qu’ils les chassent pour des raisons scientifiques alors que cela fait partie de leur culture culinaire.
    En fait, cela m’ennuie d’écrire ce qui suit mais c’est malheureusement vrai les asiatiques sont de  redoutables PRÉDATEURS.
    Notamment pour remplir leur pharmacopée imbécile dont les cornes de rhinocéros qui disparaissent de leur faute, les éléphants idem pour leur ivoire.
    Presque pire, des ours qu’ils enferment dans des cages toutes petites pour qu’ils ne puissent bouger car ils ont un drain dans le foie-et ils passent toute leur vie de cette façon!- pour prendre leur bile et il y en a plein de ce type d’exemple.
    Faites comme moi si vous voulez stoppez ces massacres: N’ACHETEZ PLUS JAMAIS DE PRODUITS ASIATIQUES, c’est comme ça que nous les ferons cesser!
