Fig. 5From: Solidified magma reservoir derived from active source seismic experiments in the Aira caldera, southern Kyushu, JapanChange in root mean squares (RMS) of travel-time residuals (O-C) of the tomographic inversion: (a) 200Â m and (b) 100Â m cell models. Gray lines indicate the RMS residuals for 100 individual initial models. Solid circles depict the mean values of the RMS residuals in each iterationBack to article page
