Fig. 5

Change in strain to illustrate visible changes in strain recorded from DAS data overlain onto lidar bare-earth imagery from November 2020. Grid coordinates per the British Grid OSGB36 datum. Topographical features near the cable are accentuated in black based on visual inspection of lidar imagery. a DAS strain on January 14, 2021 at 05:00. b DAS strain on January 14, 2021 at 10:00. c DAS strain on January 14, 2021 at 15:00. d DAS strain on January 15, 2021 at 11:00.
