Table 1 Magnitude of the geodetic volume change in the deflation source (\(\Delta V_\text{G}\)), erupted magma volume (\(\Delta V_\text{E}\)), and \(\Delta V_\text{E}/\Delta V_\text{G}\) in the later period of lava effusion during the 2011 and 2018 Shinmoe-dake eruptions (shown by shaded ranges in Fig. 2)
Year | Period | \(\Delta V_\text{G}\) (\(10^{6}\) m\(^{3}\)) | \(\Delta V_\text{E}\) (\(10^{6}\) m\(^{3}\)) | \(\Delta V_\text{E}/\Delta V_\text{G}\) |
