Spatiotemporal Variations in the Interplate Slip Rate Around Kodiak Island, Alaska

open access: yesGeophysical Research Letters
Monitoring spatiotemporal variations in the interplate slip rate during the interseismic period, such as transient strain release by slow slip events (SSEs), is crucial for characterizing the physical properties of faults.

Sumatran Megathrust Earthquakes: From Science to Saving Lives [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006
Most of the loss of life, property and well-being stemming from the great Sumatran earthquake and tsunami of 2004 could have been avoided and losses from similar future events can be largely prevented.

Megathrust Shear Modulated by Albite Metasomatism in Subduction Mélanges [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Aseismic megathrust slip downdip of the seismogenic zone is accommodated by either steady creep or episodic slow slip events (SSEs). However, the geological conditions defining the rheology of megathrust slip remain elusive.

Near-field propagation of tsunamis from megathrust earthquakes [PDF]

open access: yesGeophysical Research Letters, 2007
We investigate controls on tsunami generation and propagation in the near-field of great megathrust earthquakes using a series of numerical simulations of subduction and tsunamigenesis on the Sumatran forearc. The Sunda megathrust here is advanced in its

The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data

open access: yesGeophysical Research Letters
The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes.

Feedback between megathrust earthquake cycle and plate convergence. [PDF]

open access: yesSci Rep, 2023
AbstractOver million years, convergence between the Nazca and South America tectonic plates results in Andean orogeny. Over decades/centuries, it fuels the earthquake cycle of the Andean megathrust. It is well recognised that, over the geologically-long term of million years, Andean orogeny feeds back onto plate convergence rates, generating temporal ...

Unraveling Megathrust Seismicity [PDF]

open access: yesEos, Transactions American Geophysical Union, 2013
The majority of global seismicity originates at subduction zones, either within the converging plates or along the plate interface. In particular, events with Mw ≥ 8.0 usually occur at the subduction megathrust, which is the frictional interface between subducting and overriding plates.

Megathrust locking encoded in subduction landscapes. [PDF]

open access: yesSci Adv
Locked areas of subduction megathrusts are increasingly found to coincide with landscape features sculpted over hundreds of thousand years, yet the mechanisms that underlie such correlations remain elusive. We show that interseismic locking gradients induce increments of irreversible strain across the overriding plate manifested predominantly as ...

Cascading rupture of a megathrust

open access: yesScience Advances, 2022
Understanding variability in the size and location of large earthquakes along subduction margins is crucial for evaluating seismic and tsunami hazards. We present a coseismic slip model for the 2021 M 8.2 Chignik earthquake and investigate the relationship of this earthquake to previous major events in the Alaska ...

Nankai Forearc Structural and Seismogenic Segmentation Caused by a Magmatic Intrusion off the Kii Peninsula

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The causes for forearc basin and megathrust rupture zone segmentation are controversial. The Nankai forearc, Japan, is separated into five domains based on topography: Enshu, Kumano, Muroto, Tosa, and Hyuga.
