\"\"Jacques-Marie Bardintzeff, volcanologue, interview\u00e9 pour le Journal de France 2, \u00e0 propos du r\u00e9veil \u00e9ventuel de l\u2019Eifel.<\/p>\n

La r\u00e9gion volcanique de l\u2019Eifel se situe dans l\u2019ouest de l\u2019Allemagne, \u00e0 50 km au sud de la ville de Bonn, non loin des fronti\u00e8res belge (50 km) et luxembourgeoise (70 km). Elle s\u2019\u00e9tend sur 2 000 km2<\/sup> et culmine \u00e0 600 m.<\/p>\n

L\u2019Eifel Ouest comprend 240 centres volcaniques r\u00e9partis sur 600 km2<\/sup>. Un tiers sont des maars, r\u00e9sultant d\u2019\u00e9ruptions hydrovolcaniques (interaction explosive entre l\u2019eau et le magma), souvent occup\u00e9s par un lac. 230 \u00e9ruptions sont r\u00e9pertori\u00e9es depuis 730\u00a0000 ans. Les maars les plus r\u00e9cents sont Ulmener (10 690 ans) et Pulvermaar (10 250 ans).<\/p>\n

Dans l\u2019Eifel Est, le Laacher See, r\u00e9sulte d\u2019une formidable explosion dat\u00e9e d\u2019il y a 12\u00a0916 ans, qui lib\u00e9ra 20 km3<\/sup> de tephra (cendres et bombes), soit 6,3 km3<\/sup> DRE (Dense Rock Equivalent). La colonne \u00e9ruptive a d\u00fb monter jusqu\u2019\u00e0 40 km de hauteur. Les cendres ont atteint la France jusqu\u2019au-del\u00e0 de la vall\u00e9e de la Loire. Il reste un crat\u00e8re tout rond occup\u00e9 par un lac, \u00e0 la surface duquel l\u2019\u00e9mission permanente de bulles de gaz carbonique t\u00e9moigne d\u2019une activit\u00e9 r\u00e9siduelle.<\/p>\n

Cette zone volcanique montre certaines similitudes avec la cha\u00eene des Puys fran\u00e7aise. Elle figure dans la liste des volcans r\u00e9cents potentiellement actifs \u00e9tablie par le GVP (Global Volcanism Program), bien qu\u2019un \u00ab\u00a0r\u00e9veil \u00bb ne soit pas d\u2019actualit\u00e9 imm\u00e9diate.<\/p>\n

Des bulles de gaz carbonique \u00e9clatent \u00e0 la surface du Laacher See (\u00a9 J.M. Bardintzeff).<\/p>\n

Une publication r\u00e9cente confirme\u00a0une certaine \u00ab\u00a0activit\u00e9\u00a0\u00bb :<\/p>\n

Kreemer C., Blewitt G. et Davis P.M. – Geodetic evidence for a buoyant mantle plume beneath the Eifel volcanic area, NW Europe. Geophysical Journal International, 222, 2, 1316-1332, 2020.<\/p>\n

\u00c0 partir de nombreux relev\u00e9s GPS sur l\u2019ensemble de l\u2019Europe, entre 2000 et 2019, un soul\u00e8vement d\u2019une zone, centr\u00e9e sur l\u2019Eifel, englobant l\u2019est de la Belgique, le Luxembourg et le sud des Pays-Bas, est mis en \u00e9vidence. Cette inflation est estim\u00e9e \u00e0 1 mm par an, soit trois \u00e0 dix fois plus que la moyenne \u00e9valu\u00e9e sur les derniers 800\u00a0000 ans, associ\u00e9e \u00e0 une extension horizontale de 0,33 mm par an. Ceci t\u00e9moignerait de l\u2019activit\u00e9 du panache mantellique sous-jacent, vers 400 km de profondeur, associ\u00e9 \u00e0 un point chaud.<\/p>\n
