Various mid-to-long term observations at Stromboli and two conceptual models that may explain relative increase at STRA station in response to increased magma overpressure. [A] Observations at Stromboli prior to 2019 paroxysms compared with relative increase of velocity at STRA station (smoothed using 365-d moving window for visual simplicity). Red-dashed-lines = paroxysms, dark-green shading = 2014 flank eruption. [B] Model one: Local velocity increase near the crater terrace with velocity decrease at depth. [C] Model two: Broad velocity decrease, with reduced influence near the crater terrace. |
