Heterogeneous Crustal Structure of the Hikurangi Plateau Revealed by SHIRE Seismic Data: Origin and Implications for Plate Boundary Tectonics
Autor: Dan Bassett, Gou Fujie, Shuichi Kodaira, Ryuta Arai, Yojiro Yamamoto, Stuart Henrys, Dan Barker, Andrew Gase, Harm vanAvendonk, Nathan Bangs, Hannu Seebeck, Brook Tozer, Katie Jacobs, Thomas Luckie, David Okaya, Kimi Mochizuki
Publikováno v: Geophysical Research Letters, Vol 50, Iss 22, Pp n/a-n/a (2023)
Abstract Marine multichannel and wide‐angle seismic data constrain the distribution of seamounts, sediment cover sequence and crustal structure along a 460 km margin‐parallel transect of the Hikurangi Plateau. Seismic reflection data reveals five

Abstract Controlled and natural source seismic data are used to build a 3‐D P wave model for southern North Island, New Zealand, where the Pacific Plate subducts beneath the Australian Plate at a rate of ~41 mm/year. Our analysis reveals an abrupt

High mantle seismic P-wave speeds as a signature for gravitational spreading of superplumes
Autor: Tim Stern, Simon Lamb, Katharina Hochmuth, David Okaya, James D P Moore
Publikováno v: Science Advances
High mantle P-wave speeds beneath oceanic plateaus define a new strain fabric indicative of flow in the head of a superplume.
New passive- and active-source seismic experiments reveal unusually high mantle P-wave speeds that extend beneath the r

Resolving depth-dependent subduction zone viscosity and afterslip from postseismic displacements following the 2011 Tohoku-oki, Japan earthquake
Autor: Hiroshi Sato, Yuki Hatanaka, Andrew M. Freed, David Okaya, Akinori Hashima, Thorsten W. Becker
Publikováno v: Earth and Planetary Science Letters. 459:279-290
We developed a 3-D, viscoelastic finite element model of the M9 2011 Tohoku-oki, Japan earthquake capable of predicting postseismic displacements due to viscoelastic relaxation and afterslip. We consider seismically inferred slab geometries associate

Dense network, intense seismicity and tectonics of Taiwan
Autor: Wen-Tzong Liang, Chien Ying Wang, David Okaya, Yehuda Ben-Zion, Hao Kuo-Chen, Francis T. Wu, Zachary E. Ross
Publikováno v: Tectonophysics. 692:152-163
A temporary seismic network consisting of 295 land stations was deployed in 2009 in Taiwan to monitor airgun sources during an onshore-offshore experiment in Taiwan. We exploit the continuously recorded dataset to detect and map seismicity in the sei
