Submarine paleoseismology based on turbidite records.
Many of the largest earthquakes are generated at subduction zones or other plate boundary fault systems near enough to the coast that marine environments may record evidence of them. During and shortly after large earthquakes in the coastal and marine environments, a spectrum of evidence may be left behind, mirroring onshore paleoseismic evidence. Shaking or displacement of the seafloor can tri...
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 کاملVelocity 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 کاملTwo new species and a new record of Comesomatidae (Nematoda, Araeolaimida) from Southern Hikurangi Margin, New Zealand.
We describe two new species and provide one new species record of the family Comesomatidae from a submarine canyon habitat on the Southern Hikurangi margin, New Zealand. Vasostoma hexodontium n. sp. is characterized by having an amphideal fovea with three turns, buccal cavity with six teeth and gubernaculum with long and straight caudal apophyses. Sabatieria dispunctata n. sp. is characterized ...
