Rapid caldera subsidence and fluctuating eruption dynamics: the lithostratigraphy and structure of the Loch Bà Caldera, Isle of Mull, NW Scotland

Volcanica
Caldera-forming eruptions represent extremely hazardous events. The Loch Bà Caldera on the Isle of Mull, NW Scotland, preserves an ~120 m thick sequence of Palaeogene silicic pyroclastic rocks and collapse breccias.
