Santa Maria volcano (Guatemala), activity update: ash eruptions, lahar on 5 June

jeu., 14 juin 2007, 07:11
07:11 AM | AUTEUR : TOM PFEIFFER

Santiaguito lava dome is showing an above average level of activity. Explosions from the lava dome produce ash plumes rising to altitudes of 4.3-4.7 km (14,000-15,400 ft) a.s.l., that drift mainly to the SW.
On 5 June, a lahar (mud flow) descended the Nima I river and carried blocks 1-1.5 m in diameter and tree branches. The approximately 12-m-wide and 3-m-thick deposit was hot and smelled of sulfur. Continuous landslides of blocks and ash were noted on the SW flank.
