2604.01269 Volcanic Eruption Repose Intervals Follow Non-Proportional Hazards Across VEI Classes: A Survival Analysis of 4,792 Episodes
This study presents a comprehensive quantitative analysis of volcanic eruptions and its relationship to repose intervals, drawing on multiple decades of observational data and high-resolution numerical simulations. We develop a novel statistical framework combining wavelet decomposition, Granger causality testing, and bootstrapped trend analysis to establish robust quantitative findings.
