Understanding how strain is accumulated and released near the trench at subduction zones is crucial for a better understanding of tsunamigenic earthquakes. Some of our recent work has focused on recasting this problem as a competition between fault healing/restrengthening and tectonic loading. We used this framework to show the origins of shallow slow slip at the northern Hikurangi margin by combining experimentally determined frictional healing and numerically estimated annual stressing rates.
