Physical conditions and frictional properties in the source region of a slow-slip event
Arnulf, Adrien F.; Biemiller, James; Lavier, Luc; Wallace, Laura M.; Bassett, Dan; Henrys, Stuart; Pecher, Ingo; Crutchley, Gareth; Plaza-Faverola, Andreia (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-06)Recent geodetic studies have shown that slow-slip events can occur on subduction faults, including their shallow (<15 km depth) parts where tsunamis are also generated. Although observations of such events are now widespread, the physical conditions promoting shallow slow-slip events remain poorly understood. Here we use full waveform inversion of controlled-source seismic data from the central ... -

Splay fault branching from the Hikurangi subduction shear zone: Implications for slow slip and fluid flow
Plaza-Faverola, Andreia; Henrys, Stuart; Pecher, Ingo; Wallace, L.; Klaeschen, Dirk (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-25)Prestack depth migration data across the Hikurangi margin, East Coast of the North Island, New Zealand, are used to derive subducting slab geometry, upper crustal structure, and seismic velocities resolved to ∼14 km depth. We investigate the potential relationship between the crustal architecture, fluid migration, and short-term geodetically determined slow slip events. The subduction interface is ... -
