Fig. 2

Tilt and strain records at the AVOT, HVOT and KMT stations during the period from November 5 through 14, 2017. δR and δT represent radial and tangential tilt changes, respectively. εR, εT and εO are strain changes in the radial, tangential and oblique components, respectively. The increase in the tilt represents an upward change in a direction toward the Minami-dake crater in the radial component and in a direction rotated clockwise 90° from the crater in the tangential component. The increase in the strain represents an extension of the radial component in a direction toward the crater and a direction rotated clockwise 90° and 45° from the crater in the tangential and oblique components, respectively. The two vertical gray lines represent the start of inflation on November 7, 2017 and the onset of the explosion at Minami-dake on November 13, 2017, respectively
