Since 2004, the Sumatra subduction zone has been one of the most active on
the planet, generating 30 moderate to great earthquakes (including four Mw
≥ 8) that produced complex patterns of postseismic deformation. All these
events were recorded by the Sumatran GPS Array (SuGAr). In this talk, we
will present some of the things we’ve learned from studying nearly two
decades of SuGAR data. We will also discuss how these results fit into
long-term behavior along the subduction zone as inferred from paleogeodetic
observations from corals. We’ll talk about the varied slip behavior we see
at persistent barriers to great earthquake ruptures, 15-32-year-long slow
slip events, tsunami earthquakes, and more! We’ll also highlight the
utility of GNSS networks for climate and sea-level studies in addition to
