Interseismic Locking On The Hikurangi Subduction Zone: Uncertainties From Slow-Slip Events, Robert Mccaffrey
Interseismic Locking On The Hikurangi Subduction Zone: Uncertainties From Slow-Slip Events, Robert Mccaffrey
Geology Faculty Publications and Presentations
lnterseismic locking on the Hikurangi subduction zone in New Zealand is examined in light of alternative assumed locking distributions and the impact of transients (slow-slip and volcanic sources) on temporal and spatial resolution. The modern pattern of locking in the north is poorly resolved and, based on simulations of possible transient behavior, may be an ephemeral feature of the subduction cycle. While there appears to be some contemporary locking in the northern half of the Hikurangi subduction zone (HSZ), its location is model dependent, and hence, its relationship to structure, slow-slip, or any transition zone there is unclear. Simulations of …
