Fig. 9From: Solidified magma reservoir derived from active source seismic experiments in the Aira caldera, southern Kyushu, JapanExamples of the checkerboard resolution test (CRT) results: (a) 200 m cell model and (b) 100 m cell model. Positive and negative 5% velocity perturbations at 10 km intervals were assigned to the cells, and are depicted by blue and red circles in the figures. Other symbols are same as those in Figs. 6 and 7Back to article page
