Yellowstone : 1271 séismes en moins de 10 jours !

dont le plus important était de magnitude 3,8.
Pour mémoire, la moyenne annuelle de séismes enregistrés au Yellowstone est de 1.600 - contre 1271 en moins de 10 jours cette fois !
Selon le YVO, les séismes sont considérés comme résultants de glissements sur une faille pré-existante et qualifiés de tremblements tectoniques. Ils ne sont PAS causés par des mouvements sous-terrains de magma; il n'y a pas d'indication de future activité hydrothermale, ni volcanique.
