Velocity and anisotropy structure at the Hikurangi subduction margin, New Zealand from receiver functions
S U M M A R Y We examine seismic velocity and anisotropy at the interface between the Australian and the subducting Pacific Plate in southern North Island, New Zealand using receiver functions from teleseismic earthquakes recorded on two L-shaped seismic arrays. IRIS station SNZO makes up the corner of the southern array. Velocity models are tested with a ray theoretical method that allows both...
متن کاملPostglacial (after 18 ka) deep-sea sedimentation along the Hikurangi subduction margin (New Zealand): Characterisation, timing and origin of turbidites
10 Recent sedimentation along the Hikurangi subduction margin off northeastern New Zealand is 11 investigated using a series of piston cores collected between 2003 and 2008. The active Hikurangi 12 Margin lies along the Pacific-Australia subduction plate boundary and contains a diverse range of 13 geomorphologic settings. Slope basin stratigraphy is thick and complex, resulting from sustained h...
متن کاملEpisodic tremor and slip on the Cascadia subduction zone: the chatter of silent slip.
We found that repeated slow slip events observed on the deeper interface of the northern Cascadia subduction zone, which were at first thought to be silent, have unique nonearthquake seismic signatures. Tremorlike seismic signals were found to correlate temporally and spatially with slip events identified from crustal motion data spanning the past 6 years. During the period between slips, tremo...

متن کاملLaboratory observations of slow earthquakes and the spectrum of tectonic fault slip modes
Slow earthquakes represent an important conundrum in earthquake physics. While regular earthquakes are catastrophic events with rupture velocities governed by elastic wave speed, the processes that underlie slow fault slip phenomena, including recent discoveries of tremor, slow-slip and low-frequency earthquakes, are less understood. Theoretical models and sparse laboratory observations have pr...
