Five-minute averages of the spatial and temporal changes in strain rate for the entire observation period. a Bathymetry profile along the cable route. b Space–time plot of the average strain rate (5-min interval) for the entire observation period. c Temporal changes in the average strain rate (5-min interval) at three selected channels. The traces have been shifted vertically for comparison. d Integration of the strain rate records shown in c. Note that the scale of 1 K includes a large uncertainty as explained in the text
