Comparison of the magnitude of tilt change at KRHV with respect to that at KRMV, MKNH, and SUKH for the period from January 23 to February 2, 2011. Superimposed are lines with the following trends: KRMV/KRHV = 0.77, MKNH/KRHV = 0.48, and SUKH/KRHV = 0.13. Crosses are plotted every 12 h. Arrows indicate small fluctuations during the step-like tilt changes of KRMV. Black circles show the ratio between the magnitude of the horizontal GPS displacements of KRHV and KRMV for the period from January 25 to February 1, 2011.
