Heterogeneous rheology of Japan subduction zone revealed by postseismic deformation of the 2011 Tohoku-oki earthquake

Sambuddha Dhar et al.

Summary: The 2011 Tohoku-oki earthquake provided valuable data for studying postseismic deformation and the rheological heterogeneities of the viscoelastic earth. Researchers used a dense network of GNSS stations to investigate the different mechanisms responsible for the observed crustal deformation. However, the contribution of rheological heterogeneities to postseismic deformation is still poorly understood.

Along-arc heterogeneous rheology inferred from post-seismic deformation of the 2011 Tohoku-oki earthquake

Sambuddha Dhar et al.

Summary: The Japan forearc is important in understanding post-seismic deformation, and recent studies have shown heterogeneity in the rheology of the forearc mantle. This study investigates the variation of the stagnant part of the mantle wedge across Japan and finds along-arc heterogeneity in the forearc mantle rheology.

Spatiotemporal functional modeling of postseismic deformations after the 2011 Tohoku-Oki earthquake

Satoshi Fujiwara et al.

Summary: Postseismic deformations continue for a long period after major earthquakes and can be approximated using simple functions. Statistical data processing on postseismic deformations due to the 2011 Tohoku-Oki earthquake revealed their spatiotemporal distribution. A combined functional model of three functions was used to approximate the postseismic deformations over a wide area for approximately 10 years, but the residuals from the model deviated significantly since 2015.

Heat flow data and thermal structure in northeastern Japan

Takumi Matsumoto et al.

Summary: New heat flow data over Northeastern Japan, corrected for climate change, were obtained using the temperature profile of the borehole of the High Sensitivity Seismograph Network (Hi-net). The spatial distribution of heat flow reveals low heat flow on the forearc side, high heat flow along the Ou Backbone Range, and low heat flow in the plains on the back-arc side. However, the distribution along the VF front is not clearly divided into high and low heat flow.

Finding Simplicity in the Complexity of Postseismic Coastal Uplift and Subsidence Following Great Subduction Earthquakes

Haipeng Luo et al.

Summary: This study investigates the complexities of vertical deformation following subduction earthquakes. The results show that most megathrust earthquakes exhibit a three-segment, long-wavelength pattern of uplift and subsidence, controlled by coseismic fault slip. Afterslip, on the other hand, leads to site-specific and heterogeneous vertical deformation, but can be adequately modeled using a simple elastic model. This research has important implications for understanding the mechanism of afterslip and interpreting coastal paleoseismic records.

Postseismic geodetic signature of cold forearc mantle in subduction zones

Haipeng Luo et al.

Summary: The sharp thermal contrast between the cold forearc and the hot arc and backarc is considered crucial for various subduction zone processes, but direct observational evidence is limited. This contrast likely causes a rheological difference in the mantle wedge, impacting postseismic deformation following large subduction earthquakes. Overall, the link between long-term thermal processes and short-term earthquake cycle deformation is important for understanding subduction zone dynamics.

Postseismic Deformation due to the 2012 Mw 7.8 Haida Gwaii and 2013 Mw 7.5 Craig Earthquakes and its Implications for Regional Rheological Structure

Zhen Tian et al.

Summary: Observations of approximately 7 years of postseismic deformation following the 2012 M-w 7.8 Haida Gwaii and 2013 M-w 7.5 Craig earthquakes in western British Columbia and southeastern Alaska provide insight into regional rheologic structure and seismic hazards. A stress-driven afterslip-only model is insufficient to explain the rates and spatial patterns of the far-field postseismic deformation, leading to the development of an integrated model combining afterslip and distributed viscous flow. The integrated model suggests a 60-km thick lithosphere overlying a Burgers body asthenosphere with a Maxwell viscosity of 2 x 10(19) Pa s, in good agreement with glacial isostatic adjustment data.

N. Uchida et al.

Summary: Research has shown that there were indications of a potential great megathrust earthquake in NE Japan before the 2011 Tohoku earthquake, but a consensus assessment of the hazard was lacking. Since the earthquake, studies have made significant progress in revealing aspects such as coseismic rupture, aftershocks, and slow earthquakes.

Presence of interplate channel layer controls of slip during and after the 2011 Tohoku-Oki earthquake through the frictional characteristics

Ryoko Nakata et al.

Summary: Significant differences were found between the middle and southern segments of the Japan Trench in terms of seismic and aseismic slips, with the presence of a thick channel layer in the south causing residual gravity anomalies and impacting slip behaviors. The study suggests that this layer makes the megathrust less compliant to seismic slip but promotes aseismic slips following seismic slips in an adjacent region.

Bayesian Inversion for a Stress-Driven Model of Afterslip and Viscoelastic Relaxation: Method and Application to Postseismic Deformation Following the 2011 MW 9.0 Tohoku-Oki Earthquake

Junichi Fukuda et al.

Summary: A method for estimating the parameters of postseismic deformation models following great subduction earthquakes was developed, incorporating afterslip and viscoelastic relaxation mechanisms. Bayesian formulation and algorithm were used to estimate the posterior probability density function, allowing for quantification of uncertainties in the model parameters. Application to the 2011 Tohoku-Oki earthquake showed tight constraints on the model parameters, effectively reproducing spatial and temporal patterns of postseismic deformation.
