<\/a>Despr\u00e9s de documentar-nos en: tipus de neu, mantell nival, allaus i els seus riscos, hem demanat ajuda als Agents Rurals de la comarca donat que s\u00f3n els encarregats de passar setmanalment les dades de l\u2019estat nival de la Zona de St Maurici i Moredo a d\u2019Institut Geol\u00f2gic de Catalunya. <\/span><\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n L\u2019Institut Geol\u00f2gic de Catalunya analitza les dades procedents dels observadors nivometeorol\u00f2gics i elabora el Butllet\u00ed de Perill d\u2019Allaus (BPA) on s\u2019informa del grau de perill previst en 7 zones del Pirineu.<\/p>\n Qu\u00e8 s\u2019estudia per con\u00e8ixer l\u2019estat de la neu?<\/b><\/p>\n El m\u00e9s important \u00e9s localitzar una zona per sobre dels 2000 metres amb un pendent adient (m\u00ednim 30\u00ba).<\/p>\n Seguidament es fa el sondeig per copejament(1) amb una sonda especial per tal de calcular la resist\u00e8ncia de les diferents capes i tamb\u00e9 per con\u00e8ixer la cohesi\u00f3 de cada capa de neu. En aquest punt, i amb l\u2019ajuda d\u2019una pala, es fa un tall vertical i es descriuen les diferents capes de neu(2). De cada capa s\u2019anota la temperatura (3), el tipus de cristalls (4)i la seva mida, la duresa(5), el grau d\u2019humitat (6) i la densitat(7).<\/span> Finalment els experts fan la caracteritzaci\u00f3 de la fractura que consisteix en a\u00efllar un bloc i a partir de certa pressi\u00f3 mirar quina capa \u00e9s la que es trenca (8), coneixent d\u2019aquesta manera quina capa seria la base si es produ\u00eds una allau.<\/span><\/span><\/p>\n <\/p>\n <\/p>\n \u00a0<\/span><\/p>\n \n \n \n \n <\/p>\n <\/p>\n <\/p>\n <\/p>\n \n \n \u00a0<\/span><\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n A partir d\u2019ara veurem la neu des d\u2019un altre punt de vista.
