Heisei-Shinzan Lava Dome Deformation Time Series

This dataset contains the numerical data used in the manuscript “Long-term deformation of the Heisei-Shinzan lava dome revealed by integrated GBSAR, EDM, and DEM analysis.” The files provide the processed displacement time series and the values underlying Tables 1–3 in the paper.
Table 1 (Table1.csv): Cumulative LOS and slope-parallel displacements, terrain aspects, and the proportion of steep slopes (> 40°) for all GBSAR and EDM observation points.
Table 2 (Table2.csv): Temporal variation of Pearson correlation coefficients between cumulative displacement time series derived from GBSAR and EDM measurements at corresponding sites. Correlations are calculated annually from 2013 to 2025; high values (r > 0.7) indicate consistent displacement trends between the two methods, whereas lower values may reflect geometric effects or localized deformation.
Table 3 (Table3.csv): Volumetric change by interval at the Heisei-Shinzan lava dome. Time intervals are listed as end–start year. The level of detection was applied to Δz prior to aggregation. “Erosion” and “Deposition” are absolute volumes of negative and positive Δz (m³) after LoD masking, and “Net change” is calculated as Deposition – Erosion.
GBSAR_displacement.csv / EDM_displacement.csv: GBSAR and EDM Cumulative LOS displacement time series used to derive the above tables and figures.
These datasets provide the numerical basis needed to reproduce the deformation analysis, tables, and interpretations presented in the article.
