Fig. 7From: Groundwater pressure changes and crustal deformation before and after the 2007 and 2014 eruptions of Mt. OntakeTilt at TNH and atmospheric pressure, precipitation, and groundwater pressure at GOT from September 26 to October 4, 2014. The tilt graph is after the Japan Meteorological Agency (2014). The sampling interval for atmospheric pressure, precipitation, and groundwater pressure (except the corrected groundwater pressure) was 2 min, and that for the corrected groundwater pressure was 1 h. The period of anomalous groundwater pressure data due to problems with the water pressure sensor is shaded. The vertical dashed line indicates the onset of the eruptionBack to article page
