Deformation sources and volumetric strain change. a Deformation sources estimated from crustal deformation data obtained during the 2013 swarm activity. The red rectangles and circle indicate the locations of the shallow open cracks and the Mogi point source at a depth of 7 km, respectively. The white and red arrows show the observed and calculated tilt vectors at each borehole station, respectively. b Volumetric strain change at a depth of 0 km (sea level) calculated for the two shallow open cracks and the Mogi point source. Cross sizes indicate the changes in dv/v at each station related to the 2013 swarm activity (Fig. 6)
