A 2300‐Year Paleoearthquake Record of the Southern Alpine Fault and Fiordland Subduction Zone, New Zealand, Based on Stacked Turbidites

Turbidites from three sedimentary basins data, and probably the A.D. 1826 Fiordland earthquake and the well‐dated A.D. 1717 Alpine fault earthquake. The recurrence intervals are shorter than recently published recurrence data from the Alpine fault on land, reflecting mixed fault‐source earthquake records and potentially increased Alpine fault segmentation offshore. Online Material: Details of the laboratory methods and analytical techniques applied to sedimentrary cores, photos of seafloor substrates and fan core, OxCal codes and results, and sediment transport analysis.
