A decade of lessons learned from the 2011 Tohoku‐Oki earthquake
N Uchida, R Bürgmann - Reviews of Geophysics, 2021 - Wiley Online Library
Abstract The 2011 Mw 9.0 Tohoku‐oki earthquake is one of the world's best‐recorded
ruptures. In the aftermath of this devastating event, it is important to learn from the complete …

Stable forearc stressed by a weak megathrust: Mechanical and geodynamic implications of stress changes caused by the M= 9 Tohoku‐oki earthquake
Rupture‐zone averaged static stress drop in the 2011 M= 9 Tohoku‐Oki earthquake was
less than 5 MPa, but it caused a stress reversal in most of the offshore forearc, although the …

Seismic evidence of fluid migration in northeastern Japan after the 2011 Tohoku-Oki earthquake
We use ambient-noise-based seismic monitoring to detect an anomalous seismic velocity
decrease (∼ 0.01%) widely distributed in Honshu that arose about 1 year after the 2011 M w …

Megathrust stress drop as trigger of aftershock seismicity: Insights from the 2011 Tohoku earthquake, Japan
Numerous normal‐faulting aftershocks in subduction forearcs commonly follow large
megathrust earthquakes. Postseismic normal faulting has been explained by stress changes …

Spatial clustering of aftershocks impacts the performance of physics‐based earthquake forecasting models
JL Hardebeck - Journal of Geophysical Research: Solid Earth, 2021 - Wiley Online Library
I explore why physics‐based models of earthquake triggering rarely outperform statistical
models in prospective testing, outside of limited spatial‐temporal windows. Pseudo …

Physical properties of the crust influence aftershock locations
JL Hardebeck - Journal of Geophysical Research: Solid Earth, 2022 - Wiley Online Library
Aftershocks do not uniformly surround a mainshock, and instead occur in spatial clusters.
Spatially variable physical properties of the crust may influence the spatial distribution of …
