Fig. 8From: Precursory tilt changes of small phreatic eruptions of Meakan-dake volcano, Hokkaido, Japan, in November 2008Relative motions of GNSS stations close to the Pon-Machineshiri crater. The blue arrow expresses the horizontal movement of PMN relative to NSY reported in Ishimaru et al. (2009). The red arrow is the expected relative displacement from the dike model shown in Fig. 6a. The baseline distance between the GNSS stations is about 1 kmBack to article page
