Observations and modelling results for the 18th-19th century coral record in Simeulue. a, Subsidence rates for the two time periods, 1738–1829 (grey) and 1829-1861 (red). We assume the velocities from each epoch collectively show the average response of southern Simeulue Island to tectonic changes (filled error bar). The individual site vertical velocities are plotted with error bars, while the model predictions are shown as polygons (67% confidence level, with darker colours showing regions closer to the median). b, Estimated slip rate for 1738-1829 is shown as a grey polygon (67% confidence level). The slip rate for the period 1829-1861 is estimated using two different models: (1) steady interseismic processes with a change in locked/unlocked regions (blue polygon), (2) SSE (orange polygon) superimposed on the existing locking from 1738-1829.
