Do Coupled Megathrusts Rupture?

Megathrust earthquakes are among the most destructive and least predictable natural hazards. Kinematic geodetic coupling models, which identify regions of the plate interface where interseismic strain accumulates, are essential for seismic and tsunami hazard assessment.

Seismic‐afterslip characterization of the 2010 MW 8.8 Maule, Chile, earthquake based on moment tensor inversion

Geophysical Research Letters, 2012
On February 27th 2010, a MW8.8 earthquake struck the coast of south‐central Chile, rupturing ∼500 km along the subduction interface. Here we estimate the amount of seismically‐released afterslip (SRA) and the mechanisms underlying the distribution of ...

Depth-varying rupture properties of subduction zone megathrust faults [PDF]

, 2012
Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (M_w 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (M_w 9.0) great earthquakes had similar depth variations

Implications for megathrust earthquakes and tsunamis from seismic gaps south of Java Indonesia [PDF]

Relocation of earthquakes recorded by the agency for meteorology, climatology and geophysics (BMKG) in Indonesia and inversions of global positioning system (GPS) data reveal clear seismic gaps to the south of the island of Java.

Deformation and Slip Along the Sunda Megathrust in the Great 2005 Nias-Simeulue Earthquake [PDF]

, 2006
Seismic rupture produced spectacular tectonic deformation above a 400-kilometer strip of the Sunda megathrust, offshore northern Sumatra, in March 2005.

Seismic Evidence for Active Underplating Below the Megathrust Earthquake Zone in Japan

, 2010
Quake Control Large earthquakes occur at the margins of two colliding plates, where one plate subducts beneath the other at a shallow angle. These megathrust earthquakes often cause destructive tsunamis owing to the displacement of

On Dislocation Modeling of Megathrust Tsunami Sources

Journal of Geophysical Research: Solid Earth
AbstractModeling tsunamis due to subduction earthquakes for scientific research and hazard assessment requires accurate quantification of coseismic seafloor deformation. Although the widely used analytical model of shear dislocation in a uniform elastic half space can accommodate complex fault geometry and slip distribution, it fails to capture the ...
