Lava flows advanced northwards and reached within 5 km of Kalengera-Tongo road. This was accompanied by the opening of fissures, lava flows and strombolian eruptions. This forms what is called a subduction zone. Subduction zone recycling of volatiles (H2O, Cl, S, F) is controlled by the nature of subducted materials and the temperature-pressure profile of the downgoing slab. Subduction zone magmatic budgets and crustal growth processes depend on poorly constrained intrusive:extrusive ratios of arc magmas.
