Fig. 8From: Subsurface magma movement inferred from extensometer and tiltmeter records during the early stage of the 2018 Shinmoe-dake eruptions, JapanComparison of the geodetic volume change (\({V}_{G}\)) and DRE volume (\({V}_{D}\)) during Phases 1 and 2 of the eruption. The red line is the cumulative \({V}_{G}\) for the analysis period (Phases 1 and 2), taken from Fig. 7a, and the gray area corresponds to the cumulative 95% confidence level taken from Fig. 7a. The blue circles are the SAR-estimated \({V}_{D}\) time series (modified from NIED (2018))Back to article page
