Fig. 3From: Groundwater pressure changes and crustal deformation before and after the 2007 and 2014 eruptions of Mt. OntakeTemporal changes in the volumetric strain sensitivity to tidal components of the groundwater pressure at GOT from January 2006 to April 2015. The M2 and O1 tidal components were calculated every 61 days. The two vertical gray bars indicate periods when the well at GOT was openBack to article page
