The chemical composition of amphibole in the Ciomadul pumices shows a large variation even in a single sample. Some amphiboles represent a low-temperature, highly crystalline magma reservoir at depths of 8-12 kilometers, but most of them were transported to this shallow magma storage by higher-temperature recharge magmas coming from greater depths.

At present, the Ciomadul volcano shows no signs of reawakening. However, this study also points out that reactivation can occur rapidly, within weeks or months, in case of recharge by hot, hydrous magma.
