The sequence of events is greatly simplified (after Branney and Kokelaar, 1994). A Emplacement of the Whorneyside Formation ignimbrite and succeeding phreatoplinian ash. B Onset of piecemeal subsidence causing deformation of the Whorneyside deposits; burial beneath hot silicic ash of the Long Top Tuffs erupted from new vents. C Further collapse causing ductile deformation of the hot ignimbrite. D Paroxysmal eruptions producing very densely welded ignimbrites of the Crinkle Tuffs and causing renewed subsidence and fault-scarp collapse.E Waning eruptions and silicic dome emplacement; sedimentation in a caldera lake.
