The image depicts a graph that presents data on radial subsidence displacement measured in millimetres against axial distance also in millimetres. The x axis represents axial distance, ranging from negative fifteen hundred to positive fifteen hundred millimetres, while the y axis shows radial subsidence displacement, which varies from approximately negative one hundred and forty to zero millimetres. Six distinct lines represent different steps, each with unique markers and colours, Step one is marked in red, Step two in blue, Step three in yellow, Step four in black, Step five in green, and Step six in brown. This arrangement allows easy comparison between the displacement trends across different steps.
