Fig. 7From: Preparatory process preceding the 2014 eruption of Mount Ontake volcano, Japan: insights from precise leveling measurementsHorizontal deformation from the tensile crack model. Observed (red arrows) and calculated (blue arrows) horizontal deformations from April 2009 to October 2014 based on the tensile crack model. Error ellipses were described by 3σ. The blue rectangle denotes the location of the shrunken tensile crack. The red lines and black square denote the locations of the leveling routes and the reference point of the global navigation satellite system (GNSS), respectivelyBack to article page
