Nous avons le plaisir de vous annoncer la publication de notre article scientifique (The May 7, 2023, El-Hakimia, Algeria, Fireball: First Meteor Characterization using Infrasound and Seismic Sensors) et qui concerne le grand bolide ou m\u00e9t\u00e9ore (boule de feux) qui a travers\u00e9 le ciel alg\u00e9rien le 07 Mai 2023 \u00e0 23h59 en temps local. Il a \u00e9t\u00e9 observ\u00e9 depuis la wilaya de Mssila jusqu\u2019 au sud de l\u2019Espagne avec une magnitude lumineuse qui d\u00e9passe celle de la pleine lune. En utilisant les instruments et les capteurs du CRAAG, nous avons localiser le lieu de l\u2019explosion de ce petit ast\u00e9ro\u00efde dans l\u2019atmosph\u00e8re \u00e0 une hauteur de 35 km de la r\u00e9gion d\u2019EL Hakimia dans la wilaya de Bouira. On a estim\u00e9 que son rayon initial peut varier entre 50 cm et 1 m avec une masse initiale entre 4 et 14 tonnes. Son \u00e9nergie cin\u00e9tique initiale est \u00e9valu\u00e9e approximativement \u00e0 178 tonnes de TNT. L\u2019onde de choc de l\u2019explosion principale du bolide a \u00e9t\u00e9 d\u00e9tect\u00e9 par 14 stations sismiques de la r\u00e9gion et a induit des vibrations \u00e0 la surface du sol \u00e9quivalentes \u00e0 un s\u00e9isme local de magnitude moyenne de 2.1 sur l\u2019\u00e9chelle de Richter. La signature infrason du bolide a \u00e9t\u00e9 m\u00eame d\u00e9tect\u00e9e par des capteurs qui se situent au sud-est de l\u2019Allemagne. Cette \u00e9tude est une premi\u00e8re en Alg\u00e9rie et ouvre la porte \u00e0 des nouvelles perspectives en relation avec la d\u00e9tection des entr\u00e9s atmosph\u00e9riques.<\/p>\n\n\n\n
