Three years (2011-2013) of eruptive activity at Mt. Etna: Working modes and timescales of the modern volcano plumbing system from micro analytical studies of crystals

摘要

Tracking magma dynamics at active volcanoes by using the compositional and textural records of minerals is becoming an important aspect of modern volcanology to solve key issues, such as temporal relationships between magma recharge and eruption, duration of magma storage and final ascent upward to the surface. These issues are relevant at Mt. Etna, where the style of volcanic activity during the last years showed drastic variations in duration and intensity. The paroxysmal activity between 2011 and 2013 at the volcano summit has given the opportunity to investigate the chemical-physical processes driving the activity and to fix their spatial-temporal relationships into the plumbing system.
