The results of structural mapping show the style of deformation across Hydrate Ridge varies from SV at NHR to dominantly LV at SHR. This change in vergence is also coincident with more massive authigenic carbonate precipitation at NHR compared to SHR. These observations coupled with the distribution of gas hydrates in the subsurface and the records of slope failure at Hydrate Ridge, suggest variability in structural style may strongly influence the distribution and concentration of fluids and gas hydrates in the subsurface and the susceptibility of accretionary ridges to slope failure.
