2026-06-08 Experimental Dataset for Dynamics and Morphology of Granular Eruptions Induced by High-Pressure Gas doi:10.57760/sciencedb.38781 en This dataset comprises the raw experimental data and high-speed video recordings from a systematic investigation into the dynamics and morphological evolution of  granular media eruptions driven by high-pressure gas release. The experiments were conducted using a custom-built gas–solid eruption apparatus integrated with  high-speed imaging and synchronous measurement techniques. A total of 59 distinct working conditions were designed and systematically varied across the  dimensionless overpressure and dimensionless gas-source volume parameter space, with each condition repeated three times, yielding 177 valid experimental runs.   The Excel spreadsheet (Experimental data.xlsx) contains the quantitative measurements of eruption regime classifications, post-eruption crater morphology (normalized pit depth (d/H) and diameter (D/H)), and bubble geometric parameters (height, width, and aspect ratio (c = w/h)) as functions of (\Pi_P) and (\Pi_V).  The video folder (Experimental video-origin/) stores the original high-speed image sequences capturing the full temporal evolution of each eruption event, from  initial gas breakthrough and cavity development through column ascent, maximum expansion, decay, and final particle settlement.   This dataset supports the derivation of the regime map in the (\Pi_P)–(\Pi_V) parameter space, the fitted critical criteria for regime transitions, and the scaling laws governing crater and bubble evolution reported in the associated manuscript. granular eruption; high-pressure gas–solid interaction; crater morphology; bubble dynamics; regime map Xuefeng Zhang Peng Li PUBLIC https://creativecommons.org/licenses/by-nc-sa/4.0/ dataset Science Data Bank
