Fig. 5From: Tilt and strain change during the explosion at Minami-dake, Sakurajima, on November 13, 2017Same as Fig. 4, but for phase 2 (22:10–24:00), excluding the data of KMT and assuming dual spherical sources (source MS obtained for phase 1 and an additional deeper spherical source MD). The depths of the sources MS and MD are 0.1 km bsl and 3.3 km bsl, respectively. The error bar is the 99% confidence level estimated by an F-test (Árnadóttir and Segall 1994)Back to article page
