Seismic calm preceding volcanic eruptions is a critical predictive signal observedacross diverse volcanic systems. This study introduces an enhanced mathematicalframework to quantify its duration, integrating advanced magma flow dynamics, gasemissions, seismic attenuation, and ground deformation with non-linear correctionsand probabilistic analysis. Validated against five eruptions—Pinatubo (1991), Eyjafjallaj¨okull (2010), Santorini (pre-1650 BC), Kilauea (2018), and Etna (2021)—theframework achieves unprecedented precision, supported by comprehensive sensitivityanalysis, real-time implementation strategies, and visual comparisons with existingmodels. This integrated approach establishes a cutting-edge tool for volcanic hazardassessment and prediction, surpassing prior methodologies.
