Figure 5.
Panel a shows radial stress in kilo pascals over elapsed time from 5265 to 5285 days for multiple measurement points, where values increase sharply to about 600 kilo pascals near 5267 days, then gradually decrease to about 50 kilo pascals by 5277 days, followed by a drop to about minus 300 kilo pascals and recovery to around 300 kilo pascals after 5279 days. Panel b shows pore pressure in kilo pascals over the same time range, with values rising to about 800 kilo pascals near 5267 days, decreasing to about 100 kilo pascals, then dropping to about minus 400 kilo pascals near 5277 days and increasing again to around 200 kilo pascals after 5279 days. Panel c shows average radial stress and pore pressure, where radial stress increases to about 450 kilo pascals, then decreases to about 50 kilo pascals, drops to about minus 250 kilo pascals near 5277 days, and rises again to around 300 kilo pascals, while pore pressure follows a similar trend with lower magnitude values.Change in stress and pore pressure at the deposition hole normalised to Day 5266.00.
